In this paper, the distribution area of limnology wetland in Yinchuan plain at different times was obtained through literature analysis and remote sensing techniques. This study analyzed the evolution process of limnology wetland in Yinchuan plain under environmental change and human socio-economic activities interference. In its long geological period, limnology wetland in Yinchuan plain has experienced the process of area reduction from lake to lake. In the history of mankind and as a result of poor irrigation and drainage water with formation of low-lying land, limnology wetland area has increased in a period of time. In the last 60 years, limnology wetland shrunk rapidly because of excessive exploration of agriculture and extraction of groundwater for industrial development. The results show that the temperature and precipitation changes in environmental factors play a decisive impact on the evolution of limnology wetland in Yinchuan plain. Human activities have accelerated the trend of limnology wetland area reduction. Currently, wetland ecosystems and wetland landscape pattern still develop in a deteriorate way, but the pace of deterioration is obviously slowing down.
Key words: Yinchuan plain, limnology wetland, change trends, impact analysis, arid environment.
