长江流域的湿地资源及其恢复保护

Wetland Resource in the Yangtze Basin and Its Protection and Restoration

该文根据湿地的自然地理特征及空间分布,将长江流域的湿地大致划分为长江河口地区滨海湿地,长江中下游地区河流、湖泊湿地,长江上游云贵高原湖泊群湿地三种类型。长江流域的湿地资源在被开发利用的同时,没有得到充分的保护;加之自然环境的变迁,这些湿地面临着退化或丧失的威胁。在分析湿地的利用现状和退化原因的基础上,提出了相应的湿地恢复保护对策。

According to the physical geography characteristics and spatial distribution,wetland in the Yangtze Basin can be divided into three groups mainly: estuarial and coastal wetland, river-lake wetland in middle and lower reaches of the Yangtze River and Yunnan-Guizhou plateau lakes wetland. Due to the effects of population growth and economic development, wetlands in the Yangtze Basin could not get enough protection but were utilized fully in the mean time. So, all of these wetlands are confronted with the threats of degradation and loss. On the base of analysis to the reasons of wetland degradation, countermeasures of wetland restoration and protection are suggested in this paper. 
