摘　　要：以2021年溧阳城区土地利用和骨干河道6个水质断面逐月监测数据为基础,以监测断面为中心建立缓冲区,采用缓冲区划分、景观格局指数计算和冗余分析方法(RDA),探讨4个不同空间尺度缓冲区的土地利用结构、景观格局指数与水质的关联关系。The study was based on the Liyang urban area land use and the monthly monitoring data of 6 water quality cross-sections of backbone rivers in 2021,and buffer zones were established with the monitoring cross sections as the center.Using buffer zone division,landscape index calculation and redundancy analysis method(RDA),the correlation between land use structure,landscape pattern index and water quality in four different spatial scale buffer zones were discussed.
