| Land is the mother of wealth, is also the carrier of all production and business operation activities in agricultural park. After nearly 30 years of rapid development, agricultural park in the process of concrete construction and operation, has exposed some problems, Including the needs of sustainable development and the contradiction of land supply co., LTD is especially outstanding, In hilly regions,which areas'resources endowment, social and ecological environment,and human resources are all lack of advantages, to develop modern agriculture production is particularly difficult, Based on the current situation, agricultural park healthy sustainable development of land resources reasonable use and management must be considered. Therefore, the research of land use status, intensive management, implementation agriculture parks of rural resources, social, economic and ecological sustainable development is of great significance.Based on the location theory, land rent theory, land scale reward theory and the sustainable development theory as the foundation, the system combed the theory and method of modern agricultural park and land intensive,Peng Xi county agricultural park were analyzed in 2011-2015 land use situation and problems, constructing agricultural park land intensive utilization evaluation index system, By determining the evaluation index standard, and with the aid of the BP neural network model to carry out the quantitative evaluation, based on the comprehensive analysis of the results of the proposed Suggestions for the improvement of modern agricultural park land use intensive degree.First, define the agricultural park the connotation of intensive utilization of land. Based on theoretical analysis, this study thought connotation is the rationalization of land use structure, is to optimize the size of the space layout and; Is the moderate scale of agricultural production land, through the industry cluster play a larger radiation and demonstration impetus effect; Is full of land use, minimize the number of abandoned; Is a land of output efficiency, so as to realize the unification of the "three benefits".Second, agricultural park land intensive utilization evaluation model is constructed. Based on the situation of the agricultural park land use present situation, this study set out to use benefit, performance management from three aspects, Select 23 specific indicators, respectively, based on the BP neural network is constructed of modern agricultural park land intensive utilization evaluation model. Calculate the 2011-2015 Peng Xi county agricultural park land use intensive degree of modern agriculture is respectively:0.3921?0.5152?0.5331?0.5627?0.6320, The results show that:Since the construction, Output efficiency and utilization of land in the area of has reached the level of intensive, And growth is relatively stable, But there are still worth to improve and improve.Third, find out the loose creek county land use existing problems and the countermeasures and Suggestions. Qualitative and quantitative analysis results showed that the park there is land use demand, lack of effective supply; Weak concept of intensive land use, ecological protection consciousness is not strong; Lack of overall planning execution and quantitative appraisal mechanism is lax, Demonstration ability is weak, in driving the industry layout is not scientific problems. It is concluded that the need to strengthen the idea, and improve the resources and economic coordination degree; Revision of science, strict enforcement of land use general rules; Revitalize the stock, the mining land intensive utilization potential; Strengthen management, to establish incentive and constraint mechanism suggestion. |
