摘要: 调查了湖北赤龙湖国家湿地公园濒危水生植物粗梗水蕨的分布,分析了其分布与水质的关系;赤龙湖国家湿地公园粗梗水蕨种群的基本特征用布朗-布朗喀提出的6个多度级别以及目视方法进行了研究。结果表明粗梗水蕨主要分布在该湿地公园的沙径村、施家塘、下庙村和苏圩村4 个区域的湖汊、池塘和水沟中。4个粗梗水蕨种群面积、数量及盖度均呈现差异,但多度均较小。与粗梗水蕨相伴生的物种主要有12科11属13种。赤龙湖主要湖泊(恒丰湖)水中的硝酸盐氮(NO3--N)和总磷(P)分别为0. 4 mg/L 和0. 2 mg/L,表明赤龙湖的主要湖泊富营养化。

Abstract: The distribution of the endangered aquatic fern Ceratopteris pteridoides at Hubei Chilong Lake National Wetland Park in China was investigated. The relationship between its distribution and water quality was analyzed. We studied the population characteristics of Ceratopteris pteridoides using Braun- Blanquet′ s method and visual method. The results showed that Ceratopteris pteridoides was mainly found in lake branches,ponds and ditches at Shajing village,Shijiatang,Xiamiao village and Suwei village of the Wetland Park. The population area,number and coverage of four Ceratopteris pteridoides populations were significant different,and their abundance were smaller. It was found that 13 aquatic plant species belonging to 12 families and 11 genera in the community. Nitrate nitrogen(NO3--N)and total phosphorus(P)in the main lake(Hengfeng Lake)of Chilong Lake was 0. 4 mg/L and 0. 2 mg/L,indicating the main lake is eutrophication. Human activity such as excessive breeding and the deterioration of water quality might be the main factor responsible for the extinction of the species.
