Evaluation Of Cultivated Value Land Resource Assets Under The Leading Function Of Grain

Arable land is the lifeblood of food production,and arable land resources can not only bring farmers certain economic income and provide basic livelihood security,but also have ecological service functions such as water and soil conservation and climate regulation,etc.However,the per capita arable land area in China continues to approach the red line of arable land,and the phenomenon of non-agriculturalization and non-foodization of arable land occurs from time to time,for which China has introduced a series of arable land protection measures.Considering the serious shortage of arable land reserve resources nationwide and other problems,China has carried out arable land resource asset assessment and inventory in various places.As an important work of arable land resource asset inventory,it is crucial to reasonably define the purpose,content and method of arable land resource asset value assessment for the sustainable management and protection of arable land resource assets.Therefore,this paper constructs the theoretical basis and value assessment system of arable land resource assets based on the connotation of food dominant function and the connotation of arable land resource asset value,determines the economic value of arable land resource assets,and in view of this applies its assessment results to assist in the accurate arable land resource balance sheet,optimizes the compensation system for land acquisition,and is essential for conducting local natural resource asset management audits,effectively protecting farmers’ livelihoods and ensure the stable and sustainable development of the national economy is very important.On the basis of a systematic review and summary of relevant domestic and international literature,the research progress on natural resource asset value assessment,as well as the connotation of arable land resource asset value and assessment methods are clarified.After combing through the literature,it is found that the use of a single assessment method has certain limitations,and because traditional assessment methods do not take into account the impact of soil quality on the value of farmland resource assets.Therefore,this paper assesses the economic value of farmland resource assets based on a method that takes the characteristics and natural quality of farmland as the background conditions,combines soil potential to determine economic returns,starts from the quality of farmland itself,creates capacity through the quality of farmland and thus reflects value Next,the ecological value of arable land assets is assessed on the basis of ecosystem assessment,then the social value of arable land is assessed according to the market substitution method,and finally the total value of arable land assets under the food-dominant function is assessed by summation.Based on this,this paper selects Jinghong City,which is rich in arable land resources and is also a dual pilot site for natural resource inventory in the Ministry of Natural Resources and Yunnan Province,as a case study to assess the value of arable land resource assets as at 31 December 2021:First,the economic value of arable land resource assets is influenced by natural drivers such as organic matter content and soil texture,in addition to market supply and demand;the food production function of arable land resource assets has the strongest effect on the ecological value of arable land,while the aesthetic landscape function has the weakest effect on the ecological value of arable land;the high or low social stability value of arable land resources is related to the yield of food crops,market prices and the sowable The social security value of arable land assets is directly affected by the social insurance of rural residents,as well as the minimum living and employment security.Secondly,Jinghong City is dominated by fourth-class land,with an area of79,629.91 mu,accounting for 36.91% of the grain cultivation area in 2021,followed by third-class land accounting for 26.19% of the grain cultivation area,and the least area is fifth-class land,with an area of 25,327.12 mu,accounting for only 8.33% of the grain cultivation area.Third,the three types of values in the value structure of arable land resource assets are economic value,social value and ecological value in descending order,of which,economic value accounts for 53.45% of the total value,totalling 5.754 billion yuan;social value accounts for 28.39% of the total value,totalling 3.057 billion yuan;the ecological value generated by the ecological service function of arable land resource assets is only 1.955 billion yuan,accounting for 18.16% of the total value.
