摘　　要：以1970—2005年新疆土地利用、新疆植被类型图、新疆草地资源图、地形、遥感影像等时空数据为基础,根据新疆土地覆盖与土地利用遥感制图的分类要求与分类含义,分析各类型的对应转换关系,通过对分类图斑的进一步划分、合并、修正等步骤,完成了1970—2005年新疆土地覆盖及其动态图的制作,实现了基于土地利用、植被分布、地形以及遥感影像等时空数据的同区域、同尺度土地覆盖的遥感制图。由此表明:土地利用数据库的一些地类可以根据分类的对应关系,直接转换为土地覆盖的相应类型;对于类型及含义有差异而无法直接转换的部分,借助植被、地形及遥感影像多源数据,对土地覆盖类型进一步判读、划分和修正,实现了快速有效的新疆土地覆盖遥感制图,同时,实现了土地利用与土地覆盖数据空间的一致性。There is rich land resource and sufficient sunlight in Xinjiang,but the problems such as water resource deficient,zoology fragile,land salinization and desertization and grass-land degeneration,artificial wetlands or wetland degradation existed ubiquity. The research of land covers problem in Xinjiang is of practical significance to the reasonable use of land resource,scientific layout of industrial structure and sustainable development of human society and economy. Basing on the land use spatio-temporal data from1970 to 2005 and other multi-source database,including Xinjiang vegetation type map,Xinjiang grassland resource map,Xinjiang topography map and remote sensing image data,the authors analyzed the relationship between various type of correspondence conversion and improving the grading of forest and grassland,according to the classification requirements and meaning of the land cover and land use remote sensing mapping of Xinjiang. This study accomplished Xinjiang land cover and land dynamic map through merging,subdivision,modifying,and achieve the same region and some scale remote sensing mapping based on multi-source database from 1970 to 2005. The study also showed that the consistent types in land use database can be converted directly,while others need to modify combining multiple vegetation,topography and remote sensing data. It is an effective method to accomplish land cover remote sensing mapping,and make sure the consistent of land use and land cover spatial distribution.
