滁州市江淮分水岭区域土地适宜性评价
|
摘要
以滁州市江淮分水岭区为研究对象,运用GIS和RS相结合的方法,依据评价因子选取的原则和分水岭区实际情况,选取土壤质地、土壤侵蚀、降水、坡度、海拔5个评价因子,采用特尔菲法确定各因子的权重,并运用加权指数和与极限条件相结合的方法得到研究区耕、林、草地的适宜性评价结果。研究结果表明:最适宜作为耕地、林地、草地的面积分别为174731.77公顷、283359.19公顷和188134.55公顷,分别占研究区总面积比例为25.26%、39.30%和27.20%。根据具体不同地区分别有不同最适宜类型,为土地利用规划和退耕还林还草的地域分布提供依据,更好的实现可持续发展。
The combination of the GIS and RS technologies was applied to study the land in Jianghuai watershed area of Chuzhou.Based on the selection of evaluation factors and the actual situation of watershed area,five evaluation factors as soil texture,soil erosion,precipitation,slope and elevation are selected and determine the weight of each factor by using the Delphi method.At last this paper evaluates the suitability of cultivated land,forestry land and grass land,and to determine the best land-use programs for providing a scientific basis.
