金马河流域滩涂湿地植物多样性特征

Characteristics of Wetland Plant Diversity in Jinma River Basin

【目的】了解金马河流域治理后的滩涂湿地植物的组成和多样性。【方法】在金马河流域设置10个样地、采用典型样方法(30个样方)研究了滩涂湿地的植物物种组成和物种多样性。【结果】在调查区域内出现植物78种,隶属38科74属,以禾本科(Gramineae)、菊科(Compositae)、伞形科(Umbelliferae)为主,优势植物为斑茅(Saccharum arundinaceum)、白茅(Imperata cylindrica)和芦苇(Phragmites australis);植物物种组成和多样性指数没有表现出明显的流域规律,但均随干扰强度增加而降低。【结论】目前金马河滩涂湿地已得到较好的恢复,但其恢复进程和方向仍需要针对性地精细管理。

【Objective】The aim of the study to explore the wetland plant composition and diversity of Jinma River Basin(JRB).【Method】Based on the field survey(30 plots of 10 stands),the wetland plant diversity of JRB had been studied.【Result】The plant composition was relatively rich.There weretotal 78 species,belonging to 38 families and 74 genera.The dominant families were Gramineae,Compositae and Umbelliferae;In addition,the dominant species were Saccharum arundinaceum,Imperata cylindrica and Phragmites australis.The plant species and diversity index had no obvious pattern in the JRB.However,both plant species and diversity index decreased with increasing magnitude of human disturbance.【Conclusion】The inland mudflat wetland of JRB had be well recovered,but the recovery process and direction still needs more scientific management.
