The eco-zoning of Huaihe River Basin based on multi-source data and spatial analysis

Abstract

Using spatial analysis, multi-source data, an on-site investigation, this study carried out an integrated eco-zoning in the Huaihe River Basin (HRB) based on the spatial heterogeneity of geographical environment and ecosystem as well as human impacts. The HRB was divided into 4 eco-zones and 8 sub-eco-zones, each zone with its main ecosystem services, eco-vulnerability or eco-sensitivity. Spatial analysis techniques were used to generate zoning maps. Suggestions on the future economic development and eco-environment protection were also put forward. The result of this study can provide a scientific basis for regional ecosystem management and development planning.
