Coupling Relationship Between Land Consolidation And New Countryside Construction And Its Pattern Innovation

During the past ten years since land consolidation was again put forward by our nation, land consolidation has made a great achievement in realizing the dynamic equilibrium of the gross cultivated land, improving production conditions, increasing agricultural land comprehensive productive capacity, and ensuring grain safety. However, due to the overemphasis on the aim of increasing cultivated land area, and the neglect of the integrated function in promoting countryside construction, the coordinate development of land consolidation and countryside construction was limited. Therefore, under the new socialist countryside construction strategy of our country, studying the theory and method of the coupling relationship between land consolidation and new countryside construction and its pattern innovation, clarifying their coupling relationship, so as to adjust the aim, to optimize the function and to innovate the pattern of land consolidation, have been an important and urgent task for the purpose of revising the programming, reconstructing the layout, improving the measures of land consolidation, and promoting the healthy development of land consolidation and ensuring the implementation of new socialist countryside construction.Supported by GIS techniques and mathematic quantitative evaluation models, this dissertation systematically studied the theory and the method of the coupling relationship between land consolidation and new countryside construction and its pattern innovation. The main study contents and conclusions are as follows:1. By analyzing and summarizing the land consolidation and countryside construction researches at home and abroad, the dissertation proposed the essence of the coupling relationship between land consolidation and new countryside construction, analyzed its theory foundation, and considered that coupling relationship included content coupling, pattern coupling, and management coupling.2. The coupling relationship between land consolidation and new countryside construction is not only that of means and objectives: land consolidation is an important means of new countryside construction, and new countryside construction is the aim of land consolidation. The determination of the content, the design of the pattern and the management of land consolidation should be based on new countryside construction. In addition, they are also supplementing, promoting each other and harmoniously developeing together: Land consolidation has the function of promoting new countryside construction, and its effectiveness depends on the aim, content, pattern and management of land consolidation; only when land consolidation promotes new countryside construction, will new countryside construction provide greater space for land consolidation development.The content coupling, pattern coupling, and management coupling between land consolidation and new countryside construction are systematically analyzed, and a framework of the coupling relationship was put forward. The content coupling can be quantificationally studied by analyzing land consolidation intensity and efficiency. The security mechanism was brought forward to ensure the coordination of the coupling relationship between land consolidation and new countryside construction.3. The theory and method of level evaluation and its dynamic monitoring of new countryside construction was studied. According to the aim of new countryside construction, the evaluation index system was set up, which included 54 indexes in 11 categories of 3 aspects, namely, constraints, development and sustainability. Weight of index was reckoned on the index's effect on new countryside construction, integrated evaluation model was set up, and the gradation and classification criterion was determined. The dynamic process monitoring method of new countryside construction was put forward, and GIS technique was introduced to acquire data and to express the results.4. The concept of land consolidation intensity was put forward, which was regarded the degree of land consolidatoin activities influence on the land. The study method of land consolidation intensity and its coupling relationship with new countryside construction were proposed. Indexes were set up based on the affecting factors. The mathematical models of land consolidation project intensity and regional land consolidation intensity were set up. The spatial analysis of land consolidation intensity actual types and dynamic types were carried out with the GIS techniques. Coupling relationship was explored in the latter ways: coupling law was analyzed by setting up regression model, spatial analysis of actual type coupling and dynamic type coupling were carried out with the GIS techniques, and coupling coefficient model of land consolidation intensity and new countryside construction was established.5. The concept of land consolidation efficiency was put forward, which was a comprehensive manifestation of function and the effect of land consolidation. The meaning and the affecting factors of land consolidation efficiency were identified. Evaluation index system of land consolidation efficiency was set up, composed of 32 indexes in 5 aspects. Research method of land consolidation efficiency and its coupling relationship with new countryside construction were studied. The affecting factors of land consolidation efficiency were analyzed, and the evaluation index system was set up. The index's weight was reckoned. The integrated evaluation model and coupling coefficient model of land consolidation efficiency and new countryside construction were set up. The coupling coefficient of land consolidation efficiency and new countryside construction was calculated. Change coefficient situation of new countryside construction in different efficiency and different project types was analyzed with analysis of variance.6. Based on the pattern coupling relationship between land consolidation and new countryside construction, 6 new countryside construction oriented land consolidation patterns and their applicability were proposed, including the modern agricultural development pattern, the eco-environment improvement pattern, infrastructure improvement pattern, adapting to town construction pattern, adapting to industry construction pattern and harmonizing men-land relationship pattern. Study method of land consolidation pattern innovation was explored. Demand of new countryside construction for land consolidation pattern was discussed, and new countryside construction oriented land consolidation patterns were designed accordingly. Spatial attribute database was built with GIS. The influencial factors and applicability of each pattern were analyzed. The spatial collocation of these new patterns was carried out with GIS techniques. The security mechanism was brought forward to ensure the realization of the new pattern.7. Taking Daiyue District as an example, new countryside construction level evaluation and its dynamic monitoring were demonstrated. The result indicated that the new countryside construction level of Daiyue District was on the intermediate level of development on the whole in 2006; 12 towns were on the intermediate level of development, 6 towns were on the primary level of development, all the towns could be classified into 5 types. The new countryside construction level in Daiyue District was on the rise from 2000 to 2006 overall, but the pace of development was slow; the towns in Daiyue District could be divided into 3 types of dynamic development: 4 belonged to the high-speed development type, 6 belonged to the medium-speed development type, 8 belonged to the low- speed development type.8. Taking Daiyue District as an example, regional land consolidation intensity and its coupling relationship with new countryside construction was demonstrated. The results showed that land consolidation in Daiyue District developed rapidly from 2000 to 2006, the emphasis was transiting from land exploitation to land consolidation; the spatial distribution in hill regions was far more than that in plain area. Coupling curve type between the realization additional cultivated land rate and the average annual growth rate of gross national products in agriculture, forestry, animal husbandry and fishery was compound curve. Coupling curve types among absolute land consolidation intensity, land consolidation intensity, and the average annual growth rate of the integrated index of new countryside construction were compound curve. Coupling curve type between land consolidation relative intensity and the average annual growth rate of the integrated index of new countryside construction was hyperbola curve. Coupling among the realization rate of land consolidation potential, the realization rate of additional cultivated land, the realization rate of investment potential, and new countryside construction indexes were fit by cubic equation.In Daiyue District, the actual land consolidation intensity of towns could be divided into 4 types: intensity consolidation, hypo-intensity consolidation, moderate consolidation, and feeble consolidation. There are 4 types of actual coupling: feeble effect coupling, moderate effect coupling, hypo-intensity effect coupling, and intensity effect coupling. There are 4 dynamic types of land consolidation intensity: exquisite change, slow change, relatively steady and steady. The coupling between land consolidation intensity and new countryside construction could be divided into 4 kinds: intensity effect coupling, hypo-intensity effect coupling, moderate effect coupling, and feeble effect coupling.9. Taking 23 villages of 5 land consolidation projects implemented and 5 non-project villages which were similar in infrastructure conditions in Daiyue District as examples, land consolidation efficiency and its coupling relationship with new countryside construction was demonstrated. The result showed that 23 villages could be divided into 3 land consolidation efficiency types: high efficiency, moderate efficiency and low efficiency. The order of land consolidation efficiency in different project types was: national > provincial > city (District). 28 villages could be divided into 4 new countryside construction change types: exquisite change, slow change, relatively steady and steady; the order of land consolidation efficiency in different change types was: exquisite change > slow change > relatively steady > steady. The greater land consolidation efficiency, the greater the change of new countryside construction. Analysis of variance result showed that the impact of the different efficiency type and different project type on new countryside construction change was of significant differences; the order of new countryside construction change rates in different efficiency types was: high efficiency > moderate efficiency > low efficiency; the order of new countryside construction change rates in different project types was: national > provincial > city (District). Coupling coefficient was of significant differences in different efficiency types and different project types, which could reflect the coupling relationship between land consolidation and new countryside construction.10. Taking Daiyue District as example, new countryside construction oriented land consolidation pattern innovation was demonstrated. The result indicated that modern agricultural development pattern mainly distributed in the regions with good land condation and agricultural basis, with a total area of 90861.13 hm2. The eco-environment improvement pattern mainly distributed in the regions of mountain Culai, along the bank of Dawen river, industry concentrated area and conserved water area, with a total area of 68309.94 hm2. The infrastructure improvement pattern mainly distributed in the hilly regions that with poor transport facilities and poor agricultural production, with a total area of 66817.76 hm2. The adapting to town construction pattern mainly distributed in most regions of Zhoudian, Tianping, and in the 16 townships, with a total area of 23551.55 hm2. The adapting to industry construction pattern mainly distributed in the industry concentrated area, with a total area of 23384.15hm2. The harmonizing men-land relationship pattern was mainly located in the economically underdeveloped regions of Liangzhuang, Culai, Xiajiang, Huangxian, Zhuyang, Daolang, etc, with a total area of 41349.64 hm2.With the study of the theory, method and application of the coupling relationship between land consolidation and new countryside construction and its pattern innovation, this dissertation proposed the theory frame of the coupling relationship between land consolidation and new countryside construction, suggested the research methods, and achieved ideal results of application in Daiyue District. The research achievements will have great theoretical value and practical significance in harmonizing the coupling relationship between land consolidation and new countryside construction, innovating land consolidation pattern, and promoting the new countryside construction.
