摘要
以江苏省邳州市为研究区域 ,在地理信息系统 (GIS)的支持下对耕地分等进行了研究。采用了评价模型 S =∑Sj×Wj 进行综合分值计算 ,根据综合分值的高低将评价单元分为 6个质量等别。通过地理信息系统技术的运用 ,实现了县域耕地分等的自动化 。
Taking Pizhou County of Jiangsu Province as a case,gradation of cultivated land is made with the support of GIS The evaluation model S=∑S j×W j is designed to calculate aggregated scores, all cultivated land units in Pizhou County are divided into 6 quality grades according to the aggregated scores An automatic gradation of cultivated land at county level is achieved and more accurate results are obtained with the application of GIS.
