中文摘要：

以衡阳盆地为研究对象，应用GIS进行农业土地利用适宜性评价，应用RS获取土地利用信息，通过对比适宜农业土地利用区域和现实土地利用区域的空间分布差异，获得农业土地利用潜力区空间分布。结果表明：优先开发呈明显的沿湘江河谷的条带状分布．同时具有明显的团块特征，除了在衡山县和衡东县分布较为分散，其他县市分布皆较为集中；谨慎开发潜力区分布呈现北部较为分散、中部较为集中的态势，且沿河谷分布的条带特征较为明显；限制开发潜力区空间分布相对最为分散。

英文摘要：

A new method used to analyze spatial distribution of agriculture land use potential was proposed. Taking Hengyang basin as study area, it analyzed land use suitability first, then got land use information from RS data, finally, got spatial distribution of agriculture land use potential by comparing distribution of suitability with distribution realistic land use. The results showed that ：（1） distribution of priority to the development showed clear banded-structure along valley of Xiangjiang river, and it had clearly lumpish feature, its distribution of every county except Hengshan county and Hengdong county is concentrated. （2）Area of carefully developed region was 2 142.93 km2, and north area of study area had more scattered distribution, and south area of study area had more concentrated distribution. （3） There was large area of limited developed region, and its distribution showed most scattered. Based on the distributions of suitability and potential area, some land use strategy were propose, such as investigating the agriculture land use potential, developing planning to mine agriculture land use potential and returning more farmland to forests.
