摘要
快速城镇化对地区生态环境质量产生重要影响,及时评估生态环境质量变化对城市生态管理和规划具有重要意义。文章基于Google Earth Engine(GEE)云平台优势,利用MODIS数据对洞庭湖生态经济区的生态指数进行计算,评估了该区域20多年生态环境质量的时空变化。结果显示,近20年来洞庭湖生态经济区的生态环境质量表现出缓慢下降的趋势,下降区域主要集中于城镇周边及平原地区,其中益阳市生态环境质量最好,荆州市最差,尤其是荆州市的荆州区,在未来发展规划中需要优先引起重视。本研究成果可为环洞庭湖地区可持续发展提供重要的理论依据。
Rapid urbanization has an important impact on the quality of the regional ecological environment,and timely assessment of changes in the quality of the ecological environment is of great significance to urban ecological management and planning.Based on the advantages of the Google Earth Engine cloud platform(GEE),this paper used MODIS data to calculate the ecological index of Dongting Lake Ecological Economic Zone,and evaluated the temporal and spatial changes of the ecological environment quality in the region over the past 20 years.The results show that the ecological environment quality of Dongting Lake Ecological Economic Zone has shown a slow decline trend in the past 20 years.The declined areas are mainly concentrated in the surrounding towns and plain areas.Among them,the ecological environment quality of Yiyang City was the best,and Jingzhou City was the worst,especially Jingzhou,which need to be given priority attention in the future development planning.The research results can provide an important theoretical basis for the sustainable development of the area around Dongting Lake.
