Due to the disturbance of human activities and the influence of climate change, the water area of Mudong Lake, the core area of Huixian Wetland, the largest karst landform original wetland in the Lijiang River Basin, has shrunk and faced severe ecological and environmental risks. Using the Sentinel remote sensing image data of 65 scenes from 2017 to 2021, the water area of Mudong Lake was extracted by random forest classification. The temporal and spatial changes of the water area of Mudong Lake in the past five years were analyzed to explore the correlation between the water level and area of Mudong Lake. The results show that the water area of Mudong Lake has been relatively stable in the past five years, but the changes in the wet and dry periods are obvious; The area changes are mainly distributed in the northern part of the lake area; The correlation between water level and area is relatively good, and the correlation coefficients of different water periods are different; The correlation coefficients of the wet periods and dry season are 0.90 and 0.60, respectively.

由于人类活动扰动和气候变化的影响,漓江流域最大的岩溶地貌原生态湿地———会仙湿地的核心区域睦洞湖水域面积萎缩,面临严峻的生态环境风险。利用2017~2021年的65景Sentinel遥感影像数据,运用随机森林分类法提取睦洞湖水域面积,分析近5年睦洞湖水域面积的时空变化,结合睦洞湖水位实测数据和周边水位站数据,探讨了睦洞湖水位—面积之间的相关关系。结果表明,近5年睦洞湖水域面积相对稳定,但丰枯水期变化明显;面积变化区域主要分布在湖区北部;水位—面积关系相关性较好,不同水期的相关系数存在差异,丰水期、枯水期相关性分别为0.90、0.60。

由于人类活动扰动和气候变化的影响,漓江流域最大的岩溶地貌原生态湿地———会仙湿地的核心区域睦洞湖水域面积萎缩,面临严峻的生态环境风险。利用2017~2021年的65景Sentinel遥感影像数据,运用随机森林分类法提取睦洞湖水域面积,分析近5年睦洞湖水域面积的时空变化,结合睦洞湖水位实测数据和周边水位站数据,探讨了睦洞湖水位—面积之间的相关关系。结果表明,近5年睦洞湖水域面积相对稳定,但丰枯水期变化明显;面积变化区域主要分布在湖区北部;水位—面积关系相关性较好,不同水期的相关系数存在差异,丰水期、枯水期相关性分别为0.90、0.60。

Due to the disturbance of human activities and the influence of climate change, the water area of Mudong Lake, the core area of Huixian Wetland, the largest karst landform original wetland in the Lijiang River Basin, has shrunk and faced severe ecological and environmental risks. Using the Sentinel remote sensing image data of 65 scenes from 2017 to 2021, the water area of Mudong Lake was extracted by random forest classification. The temporal and spatial changes of the water area of Mudong Lake in the past five years were analyzed to explore the correlation between the water level and area of Mudong Lake. The results show that the water area of Mudong Lake has been relatively stable in the past five years, but the changes in the wet and dry periods are obvious; The area changes are mainly distributed in the northern part of the lake area; The correlation between water level and area is relatively good, and the correlation coefficients of different water periods are different; The correlation coefficients of the wet periods and dry season are 0.90 and 0.60, respectively.
