Analysis Of Cultivated Land Reserve Resources In Hunan Province

Many people and little land, shortage of arable land reserve resources is China’s basic national conditions. In order to realize the dynamic equilibrium of the total cultivated land, to ensure national food security, we must rely on the reserve resources of cultivated land. But in the investigation ofthe existing cultivated land reserve resources and evaluation results, reserve resources in partand part of the quality of cultivated land has ecological risk and policy risk, some so need toreserve resources of cultivated land of reservoir to sort out, to clean out the effective exploitation arable land reserve resources quantity. This paper takes Hunan Province as the study area,selected Changsha County, Hengyang County, Xiangtan County, Xiangyin County, Yuanjiang City,Hanshou County, the county, Wugang city and Xintian County nine counties as samples, thereserve resources of cultivated land survey and evaluation of existing results as the basis, analyze the limiting factors of cultivated land reserve resources calculation of reserve resources, thereclaimed land, and on the basis of reserve cultivated land resources may be willing to study, study the equilibrium of supply and demand analysis of arable land reserve resources, put forward the corresponding suggestions and measures for the protection of arable land reserve resources,realize the sustainable utilization of cultivated land reserve resources. For the final determination of land reclamation fee standards, the implementation of the most stringent farmland protection system and provide protection from the economic.This paper is divided into six parts:The first part is an introduction. Mainly introduces the research background of this paper,discusses the progress of reserve resources of cultivated land of related research at home and abroad, this paper put forward the research purpose and significance, research object and content, research methods and ideas as well as the focus of this paper.The present situation of Hunan province reserve resources of cultivated land of second parts.From the quantity and distribution, quality and distribution of cultivated land reserve resources, the status quo of the reserve cultivated land resources in Hunan province.The third part analyzes restrictive factors of reserve cultivated land resources. Because of the difference of reserve resources of cultivated land reserve resources of cultivated land and the actual survey data can be reclaimed greatly, need to analyze the restrictive factors of the development and utilization of cultivated land resources in Hunan province.The fourth part analysis of supplementary cultivated land. Through calculating the sample County exploitation arable land reserve resources, measurement of county cultivated land reserve resources can be reclaimed cultivated land coefficient, which is the limiting factor of cultivated land reserve resources can be reclaimed landform area coefficient, and then draw the exploitation arable land reserve resources quantity and quality in Hunan Province, finally based on measured.Cultivated land coefficient, analysis on the quantity and quality of cultivated land.The fifth part analyses the balance of supply and demand of arable land reserve resources. The quantity and quality of cultivated land occupation by construction through the analysis of Hunan Province, carries on the forecast to the future of our province of cultivated land occupation by construction, so as to analyze the balance of supply and demand of reserve resources of cultivated land of Hunan Province in the restrictive factors in the quantity and quality of the.The sixth part is conclusions and suggestions. A summary of the full text, and put forward to realize the sustainable utilization of cultivated land reserve resources advice to finalize the land reclamation fee standards, the implementation of the most stringent farmland protection systemand provide protection from the economic.
