摘　　要：地表覆盖(Land cover)是地表空间中各种覆被组合,是理解与获取区域自然资源与环境变化的重要参数。随着经济发展深入与自然资源消耗加速,土地利用发生剧烈的变化。土地覆盖及区域生态环境变化信息的获取,已成为研究环境变化、管理资源与可持续发展规划等的必要条件。本数据集以Landsat无云(少云)数据为基础,采用监督分类和人工识别等方式,高精度地制作了1988~2014年约每隔5年的地表覆盖分类数据。该数据具有区域代表性,可以直观地反映赣州地区的主要地表类型的变化,特别是受人为影响较大的不透水层(城市)、受环境保护影响较大的森林等面积的变化情况。Land cover is a combination of different kinds of cover in the earth’s surface,which is an important parameter to understand and obtain the regional natural resources and environmental changes.Accessing the information of land cover and regional ecological environment changes,has become a necessary condition for the study of environmental changes and management resources and sustainable development planning,when the land use changes radically with the development of economy and the acceleration of natural resources consumption.This data set using cloudless landsat data as a basic data,with supervision and artificial recognition to the information of surface,then fine production mapping of land cover classification results in one period about every 5 years from 1988 to 2014,which can directly reflect changes in Ganzhou region of the main types of surface,especially impermeable layer(city)impacted larger by human,and the forest area changes impacted by environmental protection.
