基于GIS的耕地整理潜力分析——以江西省宜春市袁州区为例

Based on GIS to Analyse the Potence of Cultivated Land Arrangement——Take Example for Yuanzhou of Yichun City in Jiangxi Province

本文探讨利用 GIS 空间分析功能对袁州区耕地整理潜力进行分析。首先利用 GIS 对袁州区的待整理耕地作坡度分析,然后在此基础上结合不同坡度级别的抽样调查结果来测算各个乡镇的耕地整理潜力与新增耕地系数,并依据新增耕系数划分潜力级别。此方法具有现实的可行性。

This paper talks about how to use spacial analysis of GIS to analyse the potence of cultivated land arrangement of Yuanzhou county. First, use GIS to analyse the distribution of the cultivated land to be arranged in separate slope grades, based on the result, and then with the results of spot survey in different slope grades, to calculate the potence and the coefficients of the potence of separate towns. The potence can be separated into different grades according to the coefficients.This method is feasible in practical applications.
