摘要
以江西省抚州市广昌县为例,探讨了运用G IS软件SuperMap D eskpro进行土地适宜性评价的方法。在可持续发展理论的指导下,结合广昌县实际情况,选取了坡度、土壤养分、水利条件等九个评价因子,将这些因子在统一的地理坐标系统下,构造评价单元层,建立评价单元属性库。确定因子对土地适宜的权重,构建土地适宜性综合评价模型,利用此模型进行土地适宜性评价。利用SuperMap生成评价结果并统计各用地类型土地面积。
The method of GIS and SuperMap Deskpro application in land suitableness evaluation is researched, given example of Guangchang county, Fuzhou city, Jiangxi province. The evaluation unit layer is created and the evaluation unit attribute database is established under the same geographical coordinate system by guiding of sustainable development theory, combining with Guangchang county reality, selecting gradient, soil nutrient, water conservancy conditions, etc. as the nine assessment factors. The integrated land suitableness evaluation mold is formed and weight of each index is set up, and applies the mold to evaluate the land suitability. The evaluation result is produce by SuperMap and statistics the area of all kinds of lands.
