基于ArcGIS的征地区片划分研究——以平邑县为例

Land Expropriation Division Based on ArcGIS—A Case Study of Pingyi County

如何快速、合理的对征地区片进行划分,进一步保障农民的合法权益,是当今政府关注的问题之一。该研究以平邑县区片划分为例,结合ArcGIS软件强大的空间分析和数据处理能力,运用Delphy法确定区片影响因素因子及权重,采用指数衰减及多因数综合评定法对各个影响因素进行赋值及综合总分值的计算。对确定后的单元综合分值采用频率直方图进行等级划分,得到平邑县区片划分等级图。

Nowadays,it is one of the concerns of our government to divide the confiscated lands into assessment units faster and reasonable,and this is of great importance to safeguard the legitimate rights and interests of farmers further.This paper takes Pingyi County of assessment units division as an example,combining powerful ArcGIS spatial analysis and data processing ability,using Delphy method to determine the influence factors of area and the weight assignment.The exponential decay and multi factor comprehensive evaluation method will be applied in assignment and comprehensive scores calculation on the factors.The unit comprehensive scores will be divided into different grades by the frequency histogram.As a result,the classification map of Pingyi County will be obtained.
