长江上游珍稀特有鱼类国家级自然保护区(宜宾段)水生植物多样性研究
Research on Plant Diversity in the National Nature Reserve of Rare and Unique Fish Species in the Upper Reaches of the Yangtze River(Yibin Section)
摘要
Abstract
This study conducted a survey and analysis of aquatic plant diversity in the national nature reserve of rare and endemic fish species in the upper reaches of the Yangtze River(hereinafter referred to as the"reserve")(Yibin section)by combining the spline method and sam-pling method.The results show that there are 229 species of plants belonging to 159 genera and 63 families in the reserve(Yibin section).The main representative plants include Persicaria chinensis,Myricaria laxiflora,Daucus carota,etc.It can be divided into"Miscanthus floridulus-Phragmites australis association","Daucus carota-Erigeron canadensis association","Salix variegata-Myricaria laxiflora association"and"Persicaria chinensis-Polypogon fugax-Vicia cracca association".The species diversity in the"Daucus carota-Erigeron canadensis association"is significantly lower than that in other associationps,indicating that invasive plants have a serious impact on local plant diversity.This study provides the first comprehensive report on the aquatic plant diversity in the reserve(Yibin section),revealing the severe impact of invasive plants on native species.It underscores the need to prioritize preventing the loss of plant diversity in the Yangtze River ecosystem and control-ling invasive species in the management of the Yibin section.关键词
