Aquatic plant diversity in relation to lake morphology in the middle and lower reaches of the Yangtze River
-
摘要: 通过野外调查、资料收集并结合GIS方法对长江中下游9个湖泊岸线形态演变和水生植物多样性现状及变化进行了研究。结果显示，近几十年来长江中下游一些湖泊岸线长度和计盒维数均显著降低；水生植物物种多样性总体呈下降趋势。相关性分析表明，湖泊岸线发育系数和湖泊计盒维数均与水生植物多样性呈显著相关；湖泊岸线形态特征显著影响沉水、漂浮植物物种多样性。本研究表明湖泊岸线形态对水生植物的生长及分布影响显著，保护湖泊岸线形态对维持水生植物多样性及湖泊生态系统功能具有重要作用。Abstract: Based on field investigation, data collection, and GIS, changes in nine lake shorelines and aquatic macrophyte diversity, as well as the relationship between aquatic plant diversity and lake morphology, were investigated in the middle and lower reaches of the Yangtze River, China. Results showed that aquatic plant species diversity, coastline length, and the box-dimension in the study area decreased markedly. Correlation analysis showed that the development coefficient and the box-dimension of the lake shorelines significantly affected aquatic plant species diversity. Shoreline morphology also significantly influenced submerged, free-floating aquatic plant diversity. These results demonstrate that lake shoreline protection plays an important role in maintaining the biodiversity of aquatic plants and lake ecosystem function.
