Abstract :
Based on MODIS data and Mann-Kendall test, our study put forward a method of combining EVI (enhanced vegetation index) and TCWI (Tasseled Cap wetness index) to monitor the ecological health of wetlands and adjacent uplands. In terms of the experimental district in Zoige Basin, a series of the ecological restoration projects implemented in recent years has not yet measurably improved the ecological health in wetlands and adjacent uplands, and the unfavorable affection from overgrazing is still obvious. The above conclusion is identical with several latest research results from other scholars based on both the post-classification change monitoring and landscape structure indices. This proves that our method is reliable; it will have great potential for popularization.
