Abstract

Wetlands are vulnerable and sensitive to climate change and human activities. Based on literature research, this paper analyzes the characteristics of wetland evolution in China. The results show that the current researches mainly focus on the wetlands of East China and North China, especially key river valleys and protected areas have attracted extensive attention. The main research methods include remote sensing, GIS, landscape index and mathematical model etc., which are still relatively simple. The area of China's natural wetland reduced by a mean of 0.19–1.67% per year, and some wetlands reach 5.56%. The constructed wetland area increased by a mean of 1.80–5.95% per year, with the increase of paddy field area. Meanwhile, the degree of fragmentation of natural wetlands in China increased by human factors. This paper analyzes China's natural wetlands generally show a trend of obvious degradation, and the relevant research results provide an important basis for wetland protection, and at the same time to provide reference for relevant policy making.
