Features of Wetland Changes in the Yellow Rivers Modern Delta During the Past 20 Years

摘要：

Wetland, as likened to a kidney of the earth, exerts irreplaceable and enormous ecological functions. However, in the late 20th century, wetland had shrunk and degraded sharply. Therefore, in order to obtain the maintenance of the healthy wetland ecosystem, the research on the evolution of wetland has been one of those imminent and momentous issues of wetland science. In this paper, on the basis of the autumn data of remote sensing in 1986, 1996 and 2004, the spatial and temporal changes of wetland landscape are investigated in the Yellow Rivers Modern Delta during the past 20 years, using the approach of landscape graph spectrum.
