该文利用景观生态学的研究方法,将耕地视为一种特殊的景观斑块,结合 GIS 技术对空间数据分析处理,利用 AHP 层次分析法,选取地形、水源条件、交通便捷性、空间布局等6个指标,建立了基于空间位置分布和空间地物相关关系的耕地适宜性评价体系,并以衡阳市松柏镇这一小区域耕地的适宜性评价为研究对象,为该区域的耕地治理、保护和合理开发提供依据.研究结果显示：松柏镇耕地斑块密度7.89,平均斑块形状指数1.6,总体聚集度指数82.07,表明该区域耕地总体表现为较为集中,不过耕地形状不规则,这对于机械化耕种有一定的不适性.通过 GIS 地理环境分析,最适宜的耕地有838.02hm2,占总耕地面积的39.22％,其所占比例最大,中等适宜的耕地有890.33hm2,占耕地总面积的34.98％,松柏镇耕地质量总体一般,部分耕地距离矿区很近,受到矿区重金属污染和大气污染较重.

The paper makes use of the research methodology of landscape ecology by taking the cultivated land as a particular landscape patch.Combining the technology of GIS to handle the spatial data analysis with the method of Analytical Hierarchy Process,six indexes were selected,which are named terrain,the requirement of headwaters,the convenience of traffic and the spatial arrangement.It sets up evaluation system framework of cultivated land suitability on account of space position distribu-tion and spatial correlation.It takes the small region of Songbai town,Hengyang city agrarian suitability assessment as the ob-ject.It can give suggestion to the land governance of protection and rational exploitation,which protects the plough from blind expansion and unscientific usage.According to the survey results,the land patch density of Songbai town is 7.89,mean patch shape index is 1.6,the overall aggregation index is 82.07,which shows that the area of cultivated land as a whole is relatively concentrated,but the arable land is irregular in shape,the mechanized farming is not suitable in this field.The most suitable cultivated land is 12570.25 acres which is the largest proportion of parts,accounting for 39.22% of the total cultivated land ar-eas.The moderate suitable cultivated land is 13354.97 acres,accounting for 34.98% of the total cultivated land areas.The quality of the cultivated land shows middle suitable in general.Part of the land is very near to mine area,where with the heavy metal pollution and air pollution.
