基于地形梯度的典型绿洲城市土地利用时空演变及其驱动因素
Spatio-temporal evolution of land use and its driving factors based on terrain gradient in typical oasis city
摘要
Abstract
Based on high-precision land use data,the terrain gradient change of land use are analyed by using terrain factors,Geodetector and PLUS model,and the driving factors of spatial differentiation and change are revealed.Results show that:from 1990 to 2020,grassland and unused land were the main land use in Urumqi,accounting for more than 83.49%,land use showed a trend of grassland and cultivated land decreasing and other types expanding.Cultivated land,water area,construction land and unused land were concentrated in low and flat areas,where altitude<1 563 m,graidient<9.61° and terrain relief<181 m.Forest land was concentrated in the undulating mountains with an elevation of 192 8~272 1 m,a slope of 15.70~47.42° and a terrain relief of 297~940 m;grassland widely distributed in the piedmont with altitude<3 176 m,slope<39.41° and terrain relief<647 m.The area change of various types of land use mainly distributed in their concentrated areas.NDVI was the dominant factor of land use spatial differentiation.关键词
