Study on the Influence of Land Use on Water Environment Quality in Riverside Zone Based on GIS

The development of the urban Binjiang belt has influenced the water environment quality. Taking the Chongqing section of the Yangtze River basin and the Binjiang section of the urban center as examples, representative water intake points were selected to extract the urban layout pattern of the Binjiang belt, and the distribution characteristics of its influence on water environment quality were studied using a geographic information system. A structural equation model was used to establish a model of the influence of urban layout on water environment quality, and the water quality test results were added to the model to calculate the contribution rates of different land types to water environment quality. The research results and methods can be used for reference for urban water environment quality and for evaluating the influence of urban design on water environment quality.
