摘要
研究生态环境质量的长时序变化特征对于协调生态环境保护战略与经济发展战略具有重要意义。本研究以宁波市为研究对象,基于Google Earth Engine(GEE)平台融合多源数据和结合遥感生态指数(RSEI)对2000—2020年间的生态环境质量进行评估。研究结果显示:宁波市的生态环境质量空间分布存在明显地区差异,高质量生态环境主要分布于宁波市南部植被茂盛地区,而低质量区域则主要位于建筑密集区或沿海地带。宁波市的生态环境质量整体呈现改善态势,南部改善程度明显优于北部,但市区及北部地区的生态环境质量呈现恶化趋势。本研究的核心创新在于利用Google Earth Engine(GEE)平台,结合RSEI,不仅精确捕捉了区域生态环境质量的变化趋势,而且为宁波市提供了规划指标量化指引和管理模式创新的启示,从而精准助力生态建设。这一成果不仅对宁波市,也对其他沿海城市在高质量发展与生态环境保护方面具有重要的指导意义,为区域生态监测和生态风险评估提供了新的视角和方法。
The long-term changes in ecological environment quality were studied to coordinate ecological environment protection strategies with economic development strategies.In this study,Ningbo City was taken as the research object,and multi-source data were integrated based on the Google Earth Engine(GEE)platform.The Remote Sensing Ecological Index(RSEI)was combined to assess the ecological environment quality(2000-2020).The spatial distribution of ecological environment quality in Ningbo City was found to have significant regional differences.High-quality ecological environments were mainly distributed in the southern areas with lush vegetation,while low-quality areas were mainly located in densely built-up areas or coastal zones.The overall ecological environment quality in Ningbo City was found to show an improving trend,with the southern area showing a more significant improvement than the northern area.However,the ecological environment quality in the urban area and the northern region was found to show a deteriorating trend.The core innovation of this study was seen in the use of the Google Earth Engine(GEE)platform combined with RSEI,which not only accurately captured the changing trends of regional ecological environment quality but also provided quantitative guidance for planning indicators and innovative insights for management models in Ningbo City,thereby accurately supporting ecological construction.This achievement was not only significant for Ningbo City but also had important guiding significance for other coastal cities in terms of high-quality development and ecological environment protection.It provided a new perspective and method for regional ecological monitoring and ecological risk assessment.
