摘要
Based on the remote sensing data and monitoring data,GIS,RS and some other advanced technologies were adopted to analyze the temporal and spatial regularities of distribution of the coastal wetlands of Yellow River Delta.The results show that: healthy,sub-healthy and morbid area accounts for 14.2%,61.9% and 23.9% in the coastal wetlands health structure of the Yellow River Delta,respectively.The main influencing factors of coastal wetlands health in the Yellow River Delta are the major regional water cycle process and its spatial and temporal variations under global climate change background,wetlands exploitation and other negative disturbances and the ecological operation in the lower reach of Yellow River.
