基于遥感数据的黄河口湿地变化研究
Research of Wetland Change in the Yellow River Estuary Region Based on Remote Sensing Data
摘要
Abstract
Based on the Landsat TM/ETM data in the Yellow River estuary region from 1992 to 2015, the changes of the Yellow River estuary wetlands were analyzed so as to further identify the reasons of wetland change and provide scientific theories for the wetland restoration.The results indicated that the Yellow River estuary wetland evolution showed significant spatial heterogeneity in recent 24 years.The total wetland area in the Yellow River estuary region decreased.Under this background,some types of wetland area increased and the others decreased,and some wetlands demonstrated a trend of fragmentation.Natural wetland was the main wetland type in the Yellow River estuary region.In recent 24 years,the natural wetland area showed a shrink-ing trend while the constructed wetland area showed an expanding trend.The total area of the Yellow River es-tuary wetland showed a trend of wetland degradation and artificialization.In the natural wetlands,the tidal wetland area was the largest;the decreasing trend of meadow wetland area was the most evident;apart from the river and lake wetland area which gently rose,other kinds of natural wetland area showed downward trends.In the constructed wetlands,the areas of reservoir and pond wetlands,salt ponds and culture ponds showed an upward trend,especially the salt ponds and culture ponds showed a strong expanding trend.The Yellow River estuary wetland change was the results of climate change,the Yellow River water and sediment and human activities for years.The assessment of relative contributions of the driving factors still needs further discussion.关键词
