| 摘 要： | 以往县级柑桔土地适宜性评价多采用定性和单要素的方法，致使评价结果中存在着主观性、片面性以及空间定位精义低等缺点。本文以江西省泰和县为研究区域，引入土地适宜度的概念，满足应用计算机进行定量评价的因子量化要求，并运用GIS技术，实现了对县级柑桔土地自然、社会经济属性适宜性进行综合评价的数量化方法，也为其他类型的单作物（广义）土地适宜性评价提供了一个可行的模式。

| Abstract: | A number of qualitative and single evaluations had been applied to the suitability of citrus land resources in the past, as a result it was hard to avoid one sidedness, subjectiveness and poor spatial location. The present paper, by taking Taihe County of Jiangxi Province as a study area, introduces the concept of land suitability degree to meet the demands of factor quantification with the aid of computer in carrying out quantitative evaluation. Meanwhile, the application of GIS technique also facilitated the integrated evaluation of natural and socio-economic attribute suitability of citrus land in quantitative method, which provides a feasible land suitability evaluation mode for other types of individual crop. |
