摘要
采用结构方程模型(structural equation modeling)方法,利用2019年水质监测数据,研究了苏州市太湖湖滨国家湿地公园、太湖国家湿地公园、同里国家湿地公园、金仓湖省级湿地公园、锦溪省级湿地公园、沙家浜国家湿地公园、太湖三山岛国家湿地公园、震泽省级湿地公园、七星揽月市级湿地公园和莲花岛-湿地生态岛屿中水体的透明度变化规律及其主要影响因素。研究结果表明,2019年,苏州市10处湿地中水体的透明度范围为50.78-128.00 cm;苏州市10处湿地中水体的透明度主要受水体中悬浮颗粒物和总有机碳含量的直接影响,藻类等内源性生产是悬浮颗粒物和总有机碳的重要来源;水温、氮磷比和风速主要通过调节水体中的总有机碳含量和叶绿素a含量对水体透明度产生间接影响。
Using the water quality monitoring data of the year of 2019, the transparency of the water bodies of Suzhou Taihu Lakeside National Wetland Park, Taihu National Wetland Park, Tongli National Wetland Park,Jincang Lake Provincial Wetland Park, Jinxi Provincial Wetland Park, Shajiabng National Wetland Park, Taihu Sanshan Island National Wetland Park, Zhenze Provincial Wetland Park, Qixing Lanyue Municipal Wetland Park, and Lianhua Island-Wetland Ecological Island in Suzhou city and its main influence factors were studied by the structural equation model. The results showed that the transparency of the water bodies in 10 wetlands in Suzhou in 2019, was in the range of 50.78-128.00 cm, which was mainly directly affected by the contents of suspended particulate matter and total organic carbon in the water bodies;the endogenous production was an important source of suspended particulate matter and total organic carbon;water temperature, ratio of total nitrogen and total phosphorus contents and wind speed mainly affect the transparency of the water bodies by adjusting the contents of total organic carbon and chlorophyll a in the water body.
