洪泽湖大型水生植物群落结构和时空格局的GIS模拟

MAPPING SPATIOTEMPORAL TRENDS IN THE ABUNDANCE AND DISTRIBUTION OF MACROPHYTES IN HONGZE LAKE

  • 摘要: 2010—2011年对洪泽湖大型水生植物进行了4个季度全面的调查和研究, 共发现大型水生植物8科12种, 其中沉水植物9种, 挺水植物1种, 浮叶植物2种。马来眼子菜(Potamogeton malaianus)、微齿眼子菜(P. maackianu)、篦齿眼子菜(P. pectinatus)和菹草(P. crispus)为全年优势度较高的水生植物, 但4个季节大型水生植物的优势种类组成差异明显。秋季的水草生物量最高, 其次为夏季和冬季, 春季最低。结合GPS (Global Position System)和GIS (Geographic Information System), 利用GIS的Kring插值法对洪泽湖大型水生植物总生物量及主要优势物种的时空分布进行了可视化模拟。结果发现洪泽湖现阶段大型水生植物分布区域主要集中在湖区北部水质较好、透明度较高且相对封闭的成子湖区。文章也分析了洪泽湖大型水生植物变迁的潜在影响因子, 为水生植物保护和生态系统健康提供了基础依据。

     

    Abstract: A comprehensive investigation on macrophyte community in Hongze Lake was conducted seasonally from May 2010 to February 2011. Overall, twelve species representing eight families of macrophytes were identified in Hongze Lake, including nine species of submerged plants, two species of floating-leaved plants, and one species of emerging plant. In general, Potamogeton malaianus, P. maackianu, P. pectinatus and P. crispus were the four dominant species throughout the whole year, the highest biomass of macrophytes was presented in autumn, followed by summer and winter, while spring had the lowest biomass of macrophytes. Based on field data, we used kriging interpolation in ArcGis to map the spatiotemporal distribution of the entire macrophyte community as well as each of the four dominant species. From the GIS maps we observed that the northern area of the lake, namely the Chengzihu region, had the highest biomass of macrophytes potentially as a result of better water quality and greater transparency. Potential factors that affected the community structure, biomass, and distribution patterns of macrophytes considerably were then discussed. The results of this study illuminate the need for more information on the role and importance of aquatic macrophytes in shallow lake ecosystems. Conservation of macrophytes should be taken to maintain the lake ecosystem health.
