Aquatic ecosystem function zoning in Jinan
摘要
Abstract
Aquatic ecosystem function regionalization is a new zoning approach based on regional differences in aquatic ecosystem. Regional heterogeneity mainly resulted from variations in geographical conditions and human activities.Aquatic ecosystem functional regionalization is an indispensable condition to realize sustainable development.By identifying spatial characteristics of terrestrial and fluvial landscapes, dividing system and criteria for regionalizing aquatic ecosystems have been established. A delineation framework was proposed to classify three-level eco-regions with geographic information system (ArcGIS).The first level eco-regions were mainly divided on the basis of three river watersheds (Yellow River,Xiaoqing River,Tuhai maj ia River)and city administrative region.Classification of the second level eco-region primarily considers spatial patterns of land use and soil factors.The third level zoning for aquatic ecosystem function regions reflects functional differences in freshwater ecosystems in the second level region.Index evaluation was used to evaluate ecological functions of aquatic biodiversity maintenance,habitat maintenance,water quality sustainment,and water resources support of the ecosystem.Dominant ecological functions were determined. Finally,classification at the third level was obtained by dominant ecological function overlay analysis with support of GIS techniques.关键词
