The Environment Variation and Analysis of Wuliangsuhai Wetland in Inner Mongolia Autonomous Region
Abstract:
Wuliangsuhai wetland located in Inner Mongolia Autonomous Region (IMAR) is selected as the study area to analyze the wetland environment variation of Inner Mongolia plateau. According to the growing conditions of water plants and the differences of water depth, the Wuliangsuhai wetland is divided into six typical areas, i.e. open water area, dense water weed area, reed area, swamp area, shallow water area and artificial reed area. The evolution trends and reasons of the six typical areas in terms of the variation of wetland characteristics are analyzed by using the Landsat TM/ETM data, the historical data and in-situ survey data. In addition, through the optimization comparison of multiple wave-band reflection combination, the regression equation of the water depth and wave band reflection combination of TM3, TM2 and TM1 is established based on the remote sensing principles, and the biological materials filling process is studied in detail. The purpose of the study is to find out the eutrophication control theory and technique measures. Due to the similar geographical and climatic conditions, the study results of Wuliangsuhai wetland could be expanded to other wetlands of Inner Mongolia plateau.
