| 摘 要： | 结合ArcGIS软件和县域耕地资源管理系统,通过原有参评因素的选取与分析,在不具备固镇县全域数据情况下,采用以局部代替全域的方法进行耕地地力等级评价,并对其方法实施的可信性进行了初步分析.结果表明:2015年固镇县耕地地力等级总体上是提升的;用局部代替全域来进行耕地地力评价的方法是科学合理的,具有可信性和可操作性.

Evaluation of Local Land Quality Change in County Area by Portion Instead of Whole Region——Took Guzhen County as an Example |
| |
| Abstract: | Combining ArcGIS software and the county cultivated land resources management system, through the original selection and analy-sis of these factors, in the absence of the whole domain data of Guzhen County, the evaluation of cultivated land quality grade was carried out by local substitution of whole-region method, and the creditability of the method implementation was analyzed preliminarily. The results showed that:In 2015, the grade of Guzhen County cultivated land was promoted in general;the method of evaluating cultivated land quality by local substitution was scientific and reasonable, and could be implemented and operable. |
