Study On The Calculating Method And Proceeds Evaluation Of Cultivated Land Requisition-compensation Balance

With the fast growth of the continuous development of social economy, the problems brought out by the reduction of the arable land are serious day and day. In order to resolve the problems of food safety, the government put forward the goal of dynamic equilibrium of total arable land. Cultivated land requisition-compensation balance was accounted for the basic measure for the dynamic equilibrium of total arable land. By the further understanding of the cultivated land requisition-compensation balance resent years, it has been developed from simplex quantity balance to quantity-quality integrated balance now, and will be developed to, further more, quantity-quality-income balance and toquantity-quality-income-ecology balance in future. On the basis of further consideration definition of classification of agricultural land and cultivated land requisition-compensation balance, the article, selecting the cultivated land quality as the research object from many contents which in great need of studying, studied the theories and methods of classification of land of agricultural land graft on the cultivated land requisition-compensation, and it offer new method to utilizing the data of the classification in the calculation of the cultivated land income in the cultivated land requisition-compensation balance, and promoting the process from quantity-quality balance to quantity-quality-income balance.The article amply expounded the meaning of cultivated land quantity-quality-income balance and analyzed the inherent logical relationship between classification of agricultural land and cultivated land requisition-compensation balance. To fulfill the need of cultivated land requisition-compensation balance in the new period, aiming at special request of quantity-quality integrated balance of cultivated land requisition-compensation balance, the article putted forward the graft between economic income evaluation module of the production of classification of agricultural land and land coefficient, and forward the grafting route way of the standard grain and the function model of economic income in the same land economic index unit. Also, with balance of cultivated land economic productivity as the basis, the article brought forward a calculation method of the equivalent coefficient of cultivated land requisition-compensation balance according to the economic income of the unit area land. This method system is a suit of scientific logical and operated easily technology supportingsystem.The article took Taihangshan piedmont region in Hebei Province as an example, launched the research of the income evaluation of cultivated land requisition-compensation balance, set up a index collection of evaluation, according to the facts of the area, and selected 121 element association. At the same time, the area was divided into five classifications of cultivated land requisition- compensation income, based on the economic income. The sampling error was made feeble though the slide average method. By the way of mathematic statistic analyses, the function medal of cultivated land income and standard grains in the same area of uniform land economic index districts was got. According to the function, the conversion of different cultivated lands of cultivated land requisition- compensation in the area could be got. The unit of which the economic index less than 0.152 should not be considered in the land compensation for its economic income is negative. The land of which the economic index is high should be supplied, so that the agricultural income is improved increasingly, and that's better to solve the problems.
