摘要
建立了一套适合矿区复垦土地评价的指标体系,提出了先对复垦土地的环境质量进行评价,当环境质量达标时再对其进行综合评价的思路。详细分析了各因子作用分值与作物产量的关系,根据因子的不同情况采取了不同的计算分值的方法,分别计算了当地正常农田的质量总分值以及复垦土地的总分值,并对两者进行了比较。
This article put forward an index system which was statable to evaluate the reclaimed land in mining area.Firstly,used this system to evaluate the environmental quality＇ s condition, if the quality was met the standard, then continued with the comprehensive evaluation of the reclaimed land in mine. This article analyzed the relations between marks of the factors and the output of the crops, and the marks of land was calculated with different ways according to the differences of factors. Finally, made a comparison between the normal farm land and the mining land, using the total marks of the two kinds of land which was calculated by the system.
