Study On Multi-purpose Value Measure And Protection Of Cultivated Land In County-scale

The cultivated land resource is a very complicated nature, ecology, social economy compound body. It is the source that the human depends on for existence. For a long time, human society generally only recognizes the economic value of the arable land, while ignoring the social and ecological value of the arable land has. Along with speeding up of rapid economic development and urbanized process, arable land is inevitable with low economic efficiency relative to non-agricultural construction land conversion, which will threaten the long-term stability of the country, damaging the fundamental interests of the masses. Under this situation, it is the necessary thorough research farming value connotation and the quantification method, advocating farmland multi-function values. While full affirmation cultivated land economic value, Enhancing the level of awareness of the public social and ecological value of farmland, with development of multi-function value of cultivated land conservation strategies, for providing protection to achieve the sustainable development of the arable land.This study includes the following main sections:The first part, On the basis of the current results of the full study at home and abroad, a clear purpose and significance of this study, the main research contents, methods and technology roadmap, and pointed out the possible innovations and shortcomings;The second part, Defined the basic concepts, Take the human relations theory, exterior innate disposition discuss, theories and so on ecological environment value theory as the instructions, clear farmland multi-function value of content and build a quantitative model; The third part, According to cultivated land multipurpose value quantification model, take Ruicheng in Shanxi province as an example of multifunctional conducted empirical research on value of cultivated land, and proposed plants crops the multi-purpose value protection the countermeasure; The fourth part, conclusions and discussion.Main conclusions of the study are as follows:(1) Multi-purpose value includes not only the economic value of cultivated land, also including social and ecological value, and the magnitude of value of the social value and ecological value of planting crops is huge.(2) Ruicheng County multi-function value of arable land in2011a total of68.429billion yuan, and Social values and ecological value of the sum of arable land were5.58times times the economic value of arable land; Plants crops the multipurpose value levels is1,086,800Yuan/hectare, the economic value is165,100Yuan/hectare, the even social value is839,500Yuan/hectare, the even ecological value is82,200Yuan/hectare.(3)2005-2011, Ruicheng County farmland function value has increased to21.953billion yuan, representing a47.23%; The multi-purpose values increase237,000Yuan/The hectare, the growth scope is27.89%, the year growth scope has achieved4.65%;2006-2011, Ruicheng County farmland multi-function value the average ring than the growth rate of6.81%。(4) Proposed plants crops the multi-purpose value protection countermeasure:a) Promote arable function values, to improve the level of public awareness, promotion of arable sustainable use; b) Arable multi-function value evaluation system, in particular to explore an effective way to achieve the farmland social and ecological value monetization metrics; c) Social and ecological value of the arable land into arable land requisition compensation standards, efforts to increase agricultural compensation, to further improve the arable land compensation mechanism; d) Implement the policy of multi-function value of the arable land protection measures, building a green national economic accounting system to achieve the coordinated development of the relationship between people and land.
