根据闽江河口湿地比较系统的调查资料,分析了生物多样性的状况及其受人为活动影响的原因,提出了湿地生物多样性保护的对策。研究表明,闽江河口区西自闽侯竹岐,东至连江川石岛,共划分10个湿地类型,总面积约459.2km2。闽江河口众多的湿地串珠状排列,有6块面积较大的湿地,是鸟类的主要栖息、繁殖和迁徙地。闽江河口湿地的维管束植物107科337属465种,被子植物89科317属438种,大型水生无脊椎动物61种,鸟类29科118种,植被类型4种类型、18个群系和22个群丛。文中分析了环境污染、不合理开发利用、盲目围垦等人为活动对闽江口湿地生物多样性的影响,最后提出了湿地生物多样性的保护对策。

The biodiversity of wetland and its prevention measures in Min River Estuary.

This paper analyzed the status of biodiversity and man-made activties threaten to the wetlands in the area of Min River Estuary,on the basic of relatively overall survey and data,putting forward countermeasures to wetland and its biodiversity.It concluded that wetland resource covers the area west from Zhuqi,Minhou County,east to Chuanshi Island,Lianjiang County,with tatal area of 459.2 square kilemeter and 10 wetland types.In the study region,6 blocks of wetlands with comparatively large area are collocated like a string of pearl naturally,which provide main inhabitants,feed sites and migration ways for immigrant birds.Wetland of Minjiang River Estuary have plenty biodiversity.There are 465 species vascular plants belonging to 337 genera and 107 families,438 species angiosperm plants belonging to 317 genera and 89 families,61 species of macroinvertebrate,and 118 species of bird with 29 families.4 types of vegetation style including 18 types of formations and 22 types of association are also founded.This paper analyzed the the human activities impacting on the biodiversity of wetland in Minjiang River Estuary,such as environmental pollution,irrationality development form and reclamation activity.Finally it concluded with some countermeasures to wetland and its biodiversity.
