Impact of Landscape Pattern Changes on Water Quality

The problem of water pollution in Changjiang River Delta region has become increasingly prominent. This chapter outlines the causes of non-point source pollution and water body deterioration in Taihu Lake Basin and analyzes the effects of landscape pattern changes on non-point source pollution, water quality, restoration of water bodies by watershed vegetation building, and various research methods to determine the impact of current landscape patterns on water quality changes. The qualitative and quantitative analysis methods of landscape pattern response to water quality are discussed. The application of landscape pattern index and “source” and “sink” landscape space load comparison index in non-point source pollution research are introduced. The research trends and research hotspots of landscape pattern are analyzed to improve water quality.
