摘　　要：以2015年遥感分类数据为基础数据源,分析河南省生态系统类型与空间分布.结果表明:河南省一级生态系统类型以耕地、森林、人工表面生态系统为主,共占全省总面积的90.550%;二级生态系统类型以水浇地、旱地、有林地、工矿用地和水田5类生态系统为主,共占全省总面积的81.189%.其中,人工表面生态系统中工矿用地占比为65.469%,湿地生态系统中湖泊水面仅占0.350.Using the classified data of remote sensing in 2015 as the basic data source,the ecological system types and spatial distribution in Henan Province were analyzed.The results showed that the primary ecological system types in Henan Province were cultivated land,forest and artificial surface ecosystems,accounting for 90.550%of the total area of the province.The secondary ecosystem types mainly included irrigated land,dry land,forest land,industrial and mining land,and paddy land,accounting for 81.189%of the total area of the province.Among them,the proportion of industrial and mining land in the artificial surface ecosystem was 65.469%,and the lake surface in the wetland ecosystem was only 0.350%.
