泉州湾河口湿地退化现状及人为影响因素

The Status and Man-made Influence Factors of Degradation of Quanzhou Estuary Wetlands

从自然湿地面积大幅减少、入侵物种互花米草(Spartina alterniflora)面积大幅增加、水环境质量恶化和生物质量下降等方面概述了泉州湾河口湿地的退化现状;认为生活污水和工业废水等污染物的排放、互花米草入侵、水利工程修建和大规模围塘养殖,是造成泉州湾河口湿地退化的主要人为影响因素。

The Quanzhou estuary wetlands are located in the southeast of Fujian province,on the west coast of Taiwan Strait,which are important wetlands of the southeast coast of China.However,in the recent several decades water quality and aquatic organism quality became worse,the invasion and proliferation spread of Spartina alterniflora happened,and aquiculture areas have been increasing.It was indicated that the ecological function of Quanzhou estury wetlands presented the degraded trend.The reasons of degradation of Quanzhou estuary wetlands included natural and man-made factors.The main man-made factors of wetland degradation in Quanzhou estuary were pollutant emission,invasion of Spartina alterniflora,the hydraulic engineering construction and extensive aquiculture area.
