Abstract:: Terrain gradient effect on geo-spectrum of land use change is one of the important research topics of land use/cover change (LUCC). Based on the remote sensing data of TM images in 2000, 2007 and Landsat8 OLI image in 2014, we took the Dianchi Basin as study area and analyzed the general trend of land use structure and geo-information spectrum, the effect and cause of terrain gradient on geo-spectrum of land use change by using method of geo-spectrum of land use change and distribution index from the perspective of the structure and geo-spectrum. The results showed that:(1) the main land use types of the study region were cultivated land, woodland, grassland and construction land, and types were transferred from cultivated land, woodland and grassland in 2000 to cultivated land, woodland and construction land in 2014; (2) geo-spectrum of land use change gave priority to stable type of the largest geo-spectrum ‘woodland-woodland-woodland’ and prophase change type of the largest geo-spectrum of ‘grassland-woodland-woodland’, both accounting for 62.59% of the total area, mainly distributed in Dianchi Lake and the north and east of Dianchi Lake; (3) geo-spectrum of land use change was clear hierarchy at terrain gradient, stable type mainly distributed at low and high terrain gradients, prophase changes type was at mid-high and high terrain gradients, the other three types of geo-spectrum land use change mainly distributed at low and mid-low terrain gradients and moved forward to mid-high terrain gradients; (4) the terrain gradient effect of geo-spectrum of land use change was mainly affected by mutual effect of basic the terrain niche, urbanization and population density, regulatory forestry resources transformation and soil and water conservation policy. This study can provided the basis for realization of reasonable allocation and sustainable development of land resources in Dianchi Basin.
