小型现代农业园区的功能分区及其应用研究

In this paper, taking the city of modern agricultural science and technology demonstration base as an example, Application of analytic hierarchy process was used to study the functional partition with GIS technology. At present, the development of modern agriculture park planning theory has made a lot of results, but there are still many problems. For example, the key aspects of the lack of systematic theoretical guidance, the majority of conceptual theory, empirical research and the macro regional studies, specific to the planning and construction of modern agricultural demonstration zone is less. Basing on the conventional modern agricultural park land of suitability evaluation system，combining with the four factors of soil nutrient status, water resources, land use and traffic location to constitute the functional division of land suitability evaluation index system. Using the Analytic Hierarchy Process to determine the weight value of each index for the four functional zones of agricultural production, science and technology demonstration area, sightseeing and entertainment district and management service area, evaluating the suitability of four different functional zoning plan overall assessment, the spatial layout planning should be in line with the requirements of rationality. Four partitions of modern agricultural park is a whole, they are not separate, but interrelated functions figured, each partition also contains a number of specific partition. By using GIS technology to weight the sum of the operation, describing the function of land suitability evaluation plan to assess the application and technology, to determine the land use suitability evaluation the results of each functional area, and finally putting forward the optimum of modern agricultural park zoning plans. This paper will convert the examining ways of the functional area of land by traditional qualitative analysis to quantitative analysis .For more rational and comprehensive analysis of the factors affecting function of the land zoning, and then come to the best plan. The results showed that, the evaluation index system added the wind and noise making proper suitability assessment system more perfect, by means of analysising the indicators for each factor on the quantification software, to make the results more scientific. In each index to quantify the process using the process of analytic hierarchy and expert interviews, this method to some extent influenced by human factors. Therefore,the results of scientific research to be improved. Under actual conditions,the factors affecting on the land suitabilit is changing, So in the further study need more improve the indicator system. It can be better able to plan for adifferent comprehensive assessment,to arrive at the best available scientific plan. By results of this study indicate that this study demonstrated the feasibility of our method, offered a new approach for the evaluation of agricultural scientific park planning and provided basis and decision support for comprehensive urban-rural land planning.
