The Study Of Dynamic Changes And Drivers Of Farmland

The farmland resources is the most important constituent in the land resource, the quantity and quality of which is the grain production basic guarantee, the certain maintenance quantity and the quality of farmland is the humanity existence and the development foundation, also is the grain security key. Change of farmland is the regional land-use change core of the natural, social, economic, technical and historical factors such as the impact of the changes and the flow of farmland reflects the socio-economic development of the basic trend.Since the China reform and open policy, the farmland resources change overall tendency performance for a change in other ways, the total area has continued to reduce. "Supports China in who" the argument and background of under the global food security crisis, the farmland loss question has caused the government and the social from all walks of life widespread attention, how to handle development and the farmland protection relations is the question which at present urgently awaits to be solved. The farmland protection is an important matter which decides by China's national condition to found a nation brings peace and order to the nation, along with economic and social development, adjusting the agricultural structure, industrialization and urbanization, as well as the promotion of eco-environmental protection and development and so on has produced the huge demand to the farmland resources, and China's WTO accession also exacerbated by the demand, so that the protection of farmland a grim situation. Under this background, the process of change and the farmland on driving mechanism, will formulate policies and regulations to protect farmland and optimize the allocation of resources, improving the efficiency of resource use have a positive meaning. The article bases directly under after Chongqing, along with the Bishan County social economy unceasing development, the industrialization and the urbanized advancement unceasingly speeds up, but plants crops the actual situation which the resources actually suddenly reduces, unifies the Bishan County 1997-2005 land data and the social economy statistical data, uses Arcgis software and the mathematical statistic software Spss comprehensive analysis influence farmland change factors; Using the principal components analytic method and the regression analytic method analysis farmland change driving influence, promulgates the farming change the actuation mechanism; Plants crops the change in view of Bishan County the actuation mechanism, proposed the protection farmland countermeasure, uses and protects the farmland for the reasonable development, the promotion economic society continues the coordinated development to provide the basis.Taking the theory of farmland resources utilization and sustainable development as our guiding ideology, the use of statistical analysis, model prediction methods and quantitative analysis of the literature, field research, political economics, systematics, ecology and other multidisciplinary qualitative analysis methods, Bishan County land resource utilization status quo, change characteristics of study.It includes six parts:Part one is introduction ,includes the background of the article and the significance of study ,study process about the subject ,and the content, characteristic of study.Part two introduce the region natural conditions and socio-economic conditions.Part three is analyzing the farmland dynamic change for Bishan County, including the quantity change and the spatial variation characteristic of farmland.Part four is analyzing the driver type, mode of action, intensity of dynamic change which qualitative and quantitative analysis unifies on the basis of part three.Part five proposes protection farmland countermeasures, in view of the farmland dynamic change factors.Part six sums up study conclusions and productions, and puts forward further studies.
