Analysis of Wetland Ecosystem Response of Poyang Lake with Water Level Evolution Base on TM Images

Abstract:

The response of wetland ecosystem of Poyang Lake influenced by hydrological process changes was addressed. The spatial distribution and area of water, water-land transition zone and exposed grass continent were obtained by classification and extraction of wetland based on Landsat-TM images and analysis of observed hydrologic data. The results indicated that wetland ecological system of Poyang Lake was characteristic of complexity,sensitivity,mutability and fragility, and the optimum water level of wetland in Poyang Lake was 10-14m.
