摘　　要：在城市化快速发展的过程中,陆地用地性质发生了巨大的变化,大量自然状态下具有截留、储存、涵养水资源等功能的绿地系统被不透水地面所代替,引发了景观格局的剧烈变化,导致了地表径流增大、降雨径流水质恶化、水资源短缺等一系列水环境问题,造成了生态系统破坏。论文以景观格局视角研究城市建设用地海绵化程度对地表径流水质的影响,分析了径流水质变化规律,得出了景观格局指数和地表径流水质之间的相关关系,为后面海绵化城市建设和保护好水生态提供新的思路。In the process of rapid urbanization,great changes have taken place in the nature of land use.A large number of green space systems with functions of retaining,storing and conserving water resources under natural conditions have been replaced by impervious ground,which has triggered drastic changes in landscape pattern and led to a series of water environment problems such as increased surface runoff,deterioration of rainfall runoff water quality and shortage of water resources.Causing ecosystem damage.From the perspective of landscape pattern,this paper studied the influence of sponginess degree of urban construction land on surface runoff and water quality,analyzed the variation law of runoff and water quality,and obtained the correlation between landscape pattern index and surface runoff and water quality,which provided a new idea for the construction of sponge city and the protection of water ecology.
