摘要
以云县为评价对象，基于ArcGIS软件的强大空间分析功能，采用层次分析法对耕地地力进行评价。评价结果显示：云县没有1级耕地分布，2~4级耕地有少量分布，占全县耕地8.23%；5~10级耕地分布较广，占全县耕地91.77%，云县耕地质量在国家标准地力等级体系中处于中等偏下水平。
Taking Yunxian County as an evaluation object, on the basis of the powerful spatial analysis function of ArcGIS software, stratifi-cation analysis method to evaluate the farmland fertility was adopted. The results showed：there was no 1st class farmland in Yunxian;there was a little distribution of 2nd to 4th class farmland, taking 8.23%of all the farmland in the county;5th to 10th class farmland was widely dis-tributed, taking 91.77%of all the farmland in the county;and the farmland quality of Yunxian County was at a lower middle level in the na-tional standard systems of soil fertility level.
