基于GIS在耕地地力评价中的应用研究——以CLRMIS平台为例

Application Research of GIS in the Evaluation of Cultivated Land Fertility

县域耕地资源管理信息系统是国内开展耕地地力评价工作的基础性平台,为了进一步完善县域耕地资源管理信息系统的功能,扬州市土壤肥料站于2011年开发出4.0版本。这一版本与以往相比做了多方面改进与加强,但是在与3.2版本的兼容性上出现了问题。以安徽省耕地地力评价工作为例,对运用4.0版本县域耕地资源管理信息系统出现的问题进行总结,并针对问题提出解决办法,供广大用户参考。

CLRMIS（County Land Resources Management Information System） is the basic platform for the evaluation of cultivated land fertility in our country.In order to further perfect the function of the CLRMIS software,the soil fertilizer stand of Yangzhou County developed CLRMIS software version 4.0 in 2011.This version has been improved and strengthened in various aspects than the previous ones.However,there are some problems due to the incompatibility with version 3.2.Taking the cultivated land fertility evaluation of Anhui Province as the example,this paper summarizes the problems in using CLRMIS software version 4.0 and suggests the corresponding solutions for the users’ reference.
