SWAT与GIS耦合的流域多要素水环境管控单元划分
Division of multi-factor water environmental control units in watersheds based on the SWAT and GIS coupled models
摘要
Abstract
This study developed a methodology for the multi-factorial control unit division and risk level assessment in a watershed,aimed at providing technical support and a decision-making basis for the refined watershed management.By integrating the SWAT model with ArcGIS technology and combining the entropy weight TOPSIS method and the Jenks natural fracture method,we have successfully delineated multi-factorial water environment control units and evaluated risk levels in the Minjiang River basin.The results indicated that the Minjiang River basin was divided into 12 control units and four control levels,including two units with a very high risk,two units with a high risk,three units with a medium risk,and five units with a low risk.The fit between the integrated attributes of each control unit and the measured element showed R2 values reaching 0.63,indicating that the delineation results can be used to reflect the spatial distribution characteristics and change trends of each element.关键词
