黄河三角洲土地覆盖与生态质量时空变化研究

Study on Spatial-Temporal Variation of Land Cover and Ecological Quality in the Yellow River Delta

摘要: 黄河三角洲是我国重要的生态资源。为了保护这一宝贵的生态系统，加强监测和管理工作、保障水资源和生态环境、加强科学研究和技术支持、加强环境治理和教育宣传工作等方面的措施是必要的，以促进其可持续发展和提高生物多样性。本文利用土地栅格数据产品、植被归一化(NDVI)数据与植被高度数据来判断黄河三角洲土地覆盖与生态质量的时空变化，以此得到近年来黄河三角洲生态环境质量有略微下降的趋势，即耕地面积增加，草本面积减少。本研究旨在深入探究黄河三角洲地区的土地利用和生态环境变化情况，为该地区的可持续发展提出相关政策建议，从而促进经济持续发展和生态环境的长期改善。

Abstract: The Yellow River Delta is an important ecological resource in China. To protect this valuable ecosystem, it is necessary to strengthen monitoring and management, guarantee water resources and ecological environment, enhance scientific research and technical support, and strengthen environmental governance and education and publicity efforts to promote its sustainable development and improve biodiversity. This article uses land grid data products, normalized vegetation difference vegetation index (NDVI) data, and vegetation height data to assess the spatial and temporal changes in land cover and ecological quality in the Yellow River Delta. It has been found that in recent years, there has been a slight decline in the ecological environment quality of the Yellow River Delta, with an increase in cultivated land area and a decrease in grassland area. This research aims to deeply explore the land use and ecological environment changes in the Yellow River Delta region, and provide relevant policy recommendations for sustainable development in the region, thereby promoting long-term improvement in economic development and ecological environment.
