松嫩平原西北部扎兰屯地区土地利用适宜性评价
EVALUATION OF LAND SUITABILITY IN ZHALANTUN AREA,NORTHWESTERN SONGNEN PLAIN
摘要
Abstract
Based on the current situation of natural resources in Zhalantun area of northwestern Songnen Plain,the land use suitability in the area is evaluated with logistic regression model and GIS technology.The results show that soil thickness,rainfall,slope aspect,slope gradient and elevation are the main indexes affecting the distribution of forest land;soil thickness,distance from roads and slope aspect for the distribution grassland;while slope gradient,soil thickness,slope aspect,population density and elevation,for the distribution of cultivated land.The AUC values of forest land,cultivated land and grassland are 0.961,0.938 and 0.755,respectively,with good fitting degree.The highly suitable area in the grassland,cultivated land and forest land suitability zoning is 3 375.85 km2,3 566.36 km2 and 5 449.91 km2,accounting for 20.11％,21.25％,and 32.47％of the total area,respectively.关键词
