摘　　要：文章基于时相为2017年的国产高分卫星遥感数据,以ARCGIS、MAPGIS及ERDAS等软件为平台,在皖江经济带76000km^2区域范围内,全面、系统、精细、现势地提取了林地、草地、湿地、荒漠化自然生态地质环境因子现状信息,建立了皖江区域自然生态因子本底数据图库,统计分析了此4大类因子类型、面积、结构、分布特征等。研究表明,皖江经济带2017年林地总面积24078.09km^2,草地总面积572.79km^2,湿地总面积11452.32km^2,荒漠化总面积495.13km^2;区域内自然生态地质环境现状局地存在问题,但总体态势良好。Based on China's high-resolution satellite remote sensing data dated in 2017,with ARCGIS,MAPGIS and ERDAS software as platforms,within 76000 km^2 area of the Wanjiang economic belt,the present situation information on natural ecological geological environment factors of forest land,grassland,wetland and desertification was extracted systematically and accurately to establish the natural ecological factors background data gallery,make statistical analysis of the factor type,area,structure,distribution and so on.The study indicates that the forest land totals 24078.09 km^2,grassland 572.79km^2,wetland 11452.32km^2,and desertification 495.13km^2 in area in 2017.The current situation of the natural ecological geological environment in the region has local problems,but the overall situation is good.
