【正文】 . Dissertation ? Ecological Land is a function of ecosystem services, landscape pattern and Spatial Heterogeneity. Affecting factors of EL Biome Total value per ha ($ ha1 yr1 ) Forest 969 Grass/rangelands 232 Wetlands 14,785 Lakes/rivers 8,498 Desert 0 Tundra 0 Ice/rock 0 Cropland 92 Urban 0 Average Global Value of Annual Terrestrial Ecosystem Services (from Constanza) WetlandWater surfaceForestGrasslandCropland . Dissertation ? Ecosystem services is related not only to landuse type, but also to landscape pattern. Affecting factors of EL ? Ecosystem function is heterogeneous spatially because of the spatial heterogeneity of physical and biological factors.. . Dissertation Spatial Model of EL EL=f (ES, LP, HE) ES: Ecosystem services。 LP: Landscape pattern。 EH: Ecological Heterogeneity ? Ecological Land should be determined by integrated significance of ecosystem services, landscape pattern and Spatial Heterogeneity. .
