基于OWBEI的黄河三角洲生态环境质量时空评价
Spatial and Temporal Evaluation of Ecological Environment Quality in the Yellow River Delta Based on OWBEI
摘要
Abstract
The Yellow River Delta is characterized by significant ecological fragility and strong disturbance by human activities,resulting in serious damage to its ecological environment.Timely and accurate evaluation of ecological environment quality in the Yellow River Delta is very important for ecological protection and policy-making.In order to solve the issue of difficult vegetation monitoring in the evaluation of wetland ecological environment quality,the improved hyperspectral image-based vegetation index(IHSVI)was proposed and applied to multi-spectral satellites.Combined with the water benefit-based ecological index(WBEI)and IHSVI,an optimized water benefit-based eco-logical index(OWBEI)was proposed to improve the retrieval accuracy of wetland ecological environment quality.The Landsat images of 2000,2006,2012,2017 and 2020 were selected to evaluate the eco-environmental quality of the Yellow River Delta based on OWBEI.The results show that OWBEI effectively improves the evaluation results of wetland ecological environment quality and the inversion accuracy is improved to 90%.The quality of the ecological environment in the inland rural areas of the Yellow River Delta is better than that of in the coastal and coastal urban areas,with 2012 as the turning point,the overall ecological environment status shows a trend of first increasing and then decreasing.关键词
