摘要
探讨湿地公园生态缓冲区土地利用结构对园内水环境质量的影响,旨在为湿地公园水环境保护与土地优化利用提供参考。文章以苏州6个国家湿地公园及其外围缓冲区为研究区域,在2019年2—10月对园内水环境质量进行监测,对不同季节水体中总氮、总磷和叶绿素的浓度变化特征进行比较分析,采用综合营养状态指数对水环境质量进行富营养化评价,运用Spearman相关性分析法对水环境质量与缓冲区土地利用结构的相关性进行分析。结果表明:1)三山岛和湖滨湿地公园水质相对较好;沙家浜、天福和同里湿地公园水质较差。2)不同季节研究区水体富营养化程度为夏>冬>春>秋。3)水环境质量与土地利用结构的相关性表现为总氮、总磷和叶绿素浓度与建设用地和耕地占比呈正相关,与林地和水域占比呈负相关;不同季节土地利用结构对水环境质量影响也存在一定差异。
This paper studies the influence of the land use structure in Suzhou Wetland Park’s ecological buffer zone on the quality of water environment in the park, in order to provide reference for wetland park management as well as regional water environment protection and land use optimization. Taking 6 national wetland parks and their peripheral buffer zones in Suzhou as the research area, the paper monitors the water environment quality in the parks from February to October 2019, and makes comparative analysis of the changes in the concentrations of total nitrogen, total phosphorus and chlorophyll in the water in different seasons. The comprehensive nutrient state index is used to evaluate the eutrophication of the water environment quality, and the Spearman correlation analysis method is used to analyze the correlation between the water environment quality and the land use structure of the buffer zone. The results show that: 1) The water quality in Sanshan Island and Lakeside Wetland Park is relatively good, while Shajiabang, Tianfu and Tongli Wetland Parks have poor water quality;2) The eutrophication of water bodies in different seasons from high to low is summer>winter>spring>autumn;3) The correlation between water environment quality and land use structure is that the concentrations of total nitrogen, total phosphorus and chlorophyll are positively correlated with the proportion of construction land and cultivated land, and negatively correlated with the proportion of forest land and water bodies. It is also found that the land use structure has different impact on water environment quality in different seasons.
