摘要：湿地水文连通性是湿地生态系统功能和健康状况的重要体现。以三江源国家公园为研究区,在整个公园、分园区和各园区的核心保育区3种尺度上,利用不同类型湿地单元之间的距离及其景观指数,来评估湿地生态系统的水文连通性。研究结果表明,长江源园区、澜沧江源园区和黄河源园区中的沼泽与河流或者湖泊之间的平均距离分别为370.7 m、408.7 m和869.9 m,索加—曲麻河、可可西里、莫云和扎陵湖—鄂陵湖核心保育区中的沼泽与河流或者湖泊之间的平均距离分别为267.1 m、294.3 m、405.8 m和673.3 m;澜沧江源园区、长江源园区和黄河源园区中的湖泊与河流之间的平均距离分别为1 736.8 m、2 933.8 m和3 868.7 m,扎陵湖—鄂陵湖、可可西里、索加—曲麻和莫云核心保育区中的湖泊与河流之间的平均距离分别为5 586.4 m、3 259.0 m、1 898.2 m和2 373.9 m;在3处园区中,长江源园区内的沼泽平均斑块面积最大,黄河源园区的湖泊最多、湖泊的斑块密度最大;在4处核心保育区中,索加—曲麻河核心保育区的沼泽平均斑块面积最大,扎陵湖—鄂陵湖核心保育区的湖泊平均斑面积最大,不同尺度下距离和景观特征呈现的湿地生态系统水文连通性非常相似。
In this paper, the study area is Three-River-Source National Park;and the research was carried out at three kinds of scales, including entire park, three sub-parks and the core conservation areas of the sub-parks.By calculating the distances between the different types of wetland units and landscape index, the hydrological connectivity of the wetlands was evaluated. The results showed that the average distances between marches and rivers or lakes in Yangtze, Lancang and Yellow River source regions were 370.7 m,408.7 m and 869.9 m, respectively, and the average distances between marches and rivers or lakes in the core conservation areas of Soja-Trama River, Kekexili, Moyun and Zaling Lake-Eling Lake were 267.1 m, 294.3 m, 405.8 m and 673.3 m, respectively. The average distances between lakes and rivers in Lancang River source, Yangtze River source and Yellow River source regions were 1 736.8 m, 2 933.8 m and 3 868.7 m,respectively, and the average distances between lakes and rivers in the Zanling Lake-Eling Lake, Kekexili,Soja-Trama River and Moyun core conservation areas were 5 586.4 m, 3 259.0 m, 1 898.2 m and 2 373.9 m,respectively. Among the three sub-parks, the Yangtze River source region had the largest average patch area of marsh wetlands, and the Yellow River source region had the largest number of lakes and the largest patch density of the lakes. For the four core conservation areas, the Soja-Trama River core conservation area had the largest average patch area of marsh wetlands, and the Zaling Lake-Eling Lake core conservation areas had the largest average patch area of the lakes. The distance and landscape features presented the results of the hydrological connectivity of the wetlands had high similarity under different scales.
