GIS支持的县级区域柑桔土地适宜性综合评价

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.
