近30年黄河三角洲生态环境遥感评价
Evaluation on Ecological Environment in the Yellow River Delta Using Remote Sensing Data in Recent 30 Years
摘要
Abstract
Affected by natural and human factors,the ecological environment of the Yellow River Delta is increasingly fragile,which restricts the sustainable development of this region.Based on four phrases Landsat data as the remote sensing data sources,we calculated a remote sensing ecological index (RSEI) combining three indicators from remote-sensing components as greenness,wet and dryness,and determined their weights based on principal component analysis.Then the spatial and temporal pattern of ecological environment in the Yellow River Delta from 1987 to 2016 was evaluated according to the RSEI.It was found that the ecological environment of the Yellow River Delta had significant differences in spatial pattern,which showed gradually deteriorating from inland to coastal areas,and the ratio of the "general" degree occupied 47.20％ ～ 58.99％ of the total research area.In the past 30 years,the eco-environmental quality of the research area declined as a whole but fluctuated during different periods.The ecological environment quality was relatively the best in 1995.The conclusion of this paper was consistent with the existing results,and it could provide some references for the ecological protection and resource development of the Yellow River Delta.关键词
