Research On County Territory Agricultural Land Grade And Appraise In Hetao Region

Agricultural lands,especially farm land, is the basic of survive and development for human. The quality of agricultural lands has direct significance to how to use agricultural lands. This article make a slight discuss to the Hetao plain in Agricultural land's grade and evaluation. It has abandoned the agricultural land classification achievement influence. It utilizes the multi-factor synthesis evaluation law, and use the advanced computer technology to carry on the grade. In the process of grading agricultural lands, it exert total area and the whole number of classical unite to decide the size of grid in agricultural lands, and check the size of grid, if the number of exotic grid as small as five percent of total grid, we acknowledge the size of grid is proper. When get the figure of grading, It has introduced the agricultural land classification thought, which utilize the economical coefficient to modify land using figure, in the agricultural land grade, use"input– output"coefficient revision grid total score value as the agricultural land to take the grade index. Through grading to the county of Wuyuan, we obtain that:1. In little differences of natural conditions in Hetao plain areas, uses the multi-factor synthesis evaluation law is the agricultural land grade most superior choice. When the social economy factor becomes the major effect factor of the agricultural land rank, the agricultural land rank's distribution assumes"Tu neng's ring"the shape distribution. The farming land level center on the government of Wuyuan, Longxingchang, and the level decrease as the distance go larger from the Longxingchang. At the same time, the degree of intensivism fall gradually. However, in the southwest of Wuyuan, this district are affected by senior city, the farming land level are higher than normal. In the land utilization way is similar to the Tu neng's "sole country" description the land utilization way.2. The grade factor's choice and the weight determination and the grade factor - nature weighing out relations table's establishment is big to the agricultural land grade result influence. The nature condition of Hetao plain has nearly different, the result of grading influence largely by social situation, therefore, through several enquiry for expert, it last decide that the weight of social affection larger than natural affection. It can promise the result of grading are much more actual and easy.On the ground of grade, it makes use of various methods to evaluate price of agricultural lands. it exert the mathematical and statistical method to procedure lots of plant's output in order to get venture rate of agricultural land. Furthermore this article detailedly elaborate that how to found,option and check the mode of formulation which make use in evaluate agricultural land's price. Through evaluating to the county of Wuyuan, we obtain that:1.The curve of agricultural land price in Wuyuan is up-inclined and scotia curve, the price upgrade as the level enlarge. The variety of price are much obvious near the Longxingchang, the elasticity of price to level close to the infinite, with the distance enlarger, the gap of price incline to the smooth, and the elasticity of price to level close to the zero. The price of agricultural land are nearly to the sell price near the urban, however, the price of agricultural land are far away the sell price at the remote area.2. It is reasonable that use the different crops sampling point the output to get the risk interest rate of agricultural land. Because agricultural land using way is diverse, so different crops'(tomato and corn) on identical land net-income existence certain difference. Therefore, it must use the average yield of three years to appraise the agricultural land price.
