The Land Consolidation And The Quality Of Cultivated Land Evaluation Research

With the further deepening of reform and opening up, China’s pace of urbanization continues to accelerate the development of the non-agricultural industries, the demand for land for the swelling, a rapid decline in arable land, the people to become increasingly acute contradictions of the protection of arable land has become China’s sustainable economic and social development of global strategic issues. To this end, the country has taken a variety of ways and means to strengthen the protection of farmland, has introduced a series of laws to ensure that the total arable land occupation and retrieval, established a highly value the rational use of land and to protect arable land, "the basic national policy.To achieve dynamic balance of the total arable land in two ways:First, the development of reserve resources to increase the arable land, the second is the internal potential to improve the degree of land use through land remediation measures on the existing land. However, due to the lack of reserve resources of China’s arable land, developed land has little potential, so only through the internal potential to achieve dynamic balance of the total arable land. In the process of urbanization, the urban construction land increased demand for more and more prominent with the contradictions of arable land in need of protection. The land consolidation as the balance of arable land, one of the main complement of arable land, on the realization of the arable land occupation and retrieval plays a very important role. Land consolidation can increase the cultivated area, improve the quality of arable land, improve the quality of cultivated land is equivalent to the increase in cultivated area, in the dynamic equilibrium of the total arable land in the practice can be both as the overall balance of factors.In recent years, to the rational organization and adjustment of status of land use, land utilization and yield, improve the living conditions of agricultural production and rationalize the relationship to the land, the country vigorously carry out land development work. Practice has proved that the land consolidation to increase the arable land, increase the use of intensive land. However, in the land development process, often focus only on the amount of cultivated land increased the quality of cultivated land, while ignoring the new, easy to cause the amount of cultivated land balance and cause serious degradation of the quality of arable land. Therefore, the land is the added land quality assessment is necessary before final acceptance of land development projects, the results have an important role in the project after the implementation of land ownership adjustments, but also for the valuation of agricultural land and other land management to provide a scientific basis. Land consolidation engineering measures to supplement the amount of cultivated land, to improve conditions for agricultural production, improve comprehensive agricultural production capacity, project area of cultivated land. In the acceptance process of the actual project, the amount of cultivated land indicators are easy to identify, and also facilitate the acceptance and quality of arable land is difficult to define and measure project completion and acceptance of difficulty.On the basis of summing up the research and progress, and field surveys, qualitative analysis and quantitative analysis of the combination of theoretical discussion and case study of a combination of around Qianjiang District Rural Land Consolidation study the issue. Explore the land consolidation project area land quality evaluation index system and method, and follow the program the scientific, economic rationality, the practical feasibility of the principle of the various technical aspects of research quality evaluation methods, develop procedures for the application of the evaluation. In accordance with the requirements of the proposed land quality assessment method, study how to organize the actual assessment of the project area the project areas around land-level analysis of land consolidation that land quality and efficiency, and promote the use of the land consolidation project.The first part describes the basic concept and content of land consolidation and land quality, as well as the relationship between land consolidation and land quality, land quality indicators of the status quo analysis of the land consolidation of arable land quality evaluation method, described This paper aims, contents and methods. The second part focuses on the theoretical basis of the quality of arable land evaluation of land consolidation. Land consolidation, the theoretical basis of land evaluation and the evaluation of the quality of cultivated land are described.The third part on the basis of the foregoing study focuses on arable land quality evaluation of land consolidation. Described the purpose of the evaluation of land consolidation of farmland quality, evaluation of the principle of selection for the index factor, combined with research index factor screening. Finalized the land consolidation of arable land evaluation method of quality assessment and evaluation process.Qianjiang District Land Consolidation Project quality of arable land were evaluated in Part IV. On the basis of existing research, and the characteristics of the area of Qianjiang District, selected for local evaluation factor, the initial establishment of land consolidation, land quality indicators, and multi-factor comprehensive evaluation method The quality of arable land in the project area before and after finishing evaluation. The evaluation results show that the number of arable land in the project area after finishing than before finishing has improved greatly, but the project area land to improve the quality of the effect is not very significant. The example showed that the land consolidation, land quality indicators should not only consider the regional differences, but also to consider the characteristics of the project itself. System of quality indicators should focus on selection due to construction projects due to relatively large changes in indicators before and after land consolidation, little change in indicators before and after land consolidation may from time to evaluation. This study can provide a basis for acceptance of the quality of the land for land access management project, but also provide a reference standard for the Chongqing area of land consolidation policy and ownership of adjustment programs.Conclusions and outlook of the fifth part of this article. Land consolidation, land quality indicators should not only consider the regional differences, but also consider the characteristics of the project itself; the application of mathematical methods and GIS technology to build a land consolidation of arable land quality evaluation system and the establishment of a mathematical model. Land consolidation, land quality evaluation process should be combined with the characteristics of the project, to avoid subjectivity, it is necessary to, combined with socio-economic factors and national policies in the system of land quality indicators for home and abroad on the basis of the system, summed up the establishment of the Land Consolidation different types of multi-scale land quality indicators.
