Evaluation Of The Effectiveness Of The Use Of Arable Land

The arable land Characteristics of natural and economic characteristics determine the value of the multi-dimensional nature of arable land, including the value of goods in kind, social carrying value of the comfort value of the services, the value of resources, ecological value, and so on. The use of arable land to complete the conversion value of the land will be cultivated land into arable land and the output value, we have had effectiveness of the use of arable land. This article attempts to land-use evaluation of the effectiveness of the analysis, the analytical framework is that the theoretical value of the land from farmland to build effective use of evaluation index system, using principal component analysis, cluster analysis and related analysis, the effective index of arable land So that it will have comparable time and space; Take Chongqing as an example in order to carry out evaluation of the empirical analysis to analyze the results as the basis, to improve the use of arable land in Chongqing effective policy recommendations.The main conclusion is: (l)The use of arable land ecological benefits depends primarily on environmental quality index of arable land, energy production value of￥10,000 and the multiple crop index. Empirical analysis found that the use of arable land in Chongqing ecological efficiency, high power output million; (2)The use of arable land depends largely on the social benefits to meet the needs of society, support agriculture and per capita arable land. The use of arable land in Chongqing social benefits of low per capita arable land continued to decline in arable land in the social security function to weaken. (3)The use of arable land depends largely on the economic benefits of grain production area, producing more than vote, and labor productivity, efficiency and technical level of mechanization. Chongqing City, the economic benefits of better use of arable land, but the anti-risk ability of lower natural disasters such as the economic benefits of a significant negative effect. (4) Overall efficiency of the use of arable land is eco-efficiency, social and economic benefits of organic unity, the effectiveness of any decline in overall efficiency will lead to decline in the use of arable land to achieve maximum benefit, we must achieve balance in advance of the three major benefits. The low efficiency comprehensive arable land use in Chongqing, mainly by the ecological and social benefits.For the low efficiency comprehensive arable land use in Chongqing the following policy recommendations were made in this paper: the establishment and improvement of the circulation system of agricultural land, cultivated land steadily scale operation; adjusting the agricultural structure, characteristics and the development of agriculture; to promote the application of agricultural technology and promote agricultural technology Progress; to increase agricultural development and building a high and stable yield farmland, to speed up agricultural infrastructure construction, improve the basic conditions for agricultural production.
