摘　　要：水体和植被是生态空间的主要表现,其动态研究是区域生态建设和生态空间规划的必要前提和基础。基于2010年和2020年德州市遥感数据,以归一化植被指数(NDVI)和归一化水体指数(NDWI)为主要指标探究其生态空间的变化趋势,旨在为德州市生态建设和生态空间规划提供科学依据。结果表明,德州市的NDVI有所下降,NDWI有所上升,区域生态空间有所改善。其中,生态状况明显改善的有德城区以及平原县,分布于德州市的西北部和中西部;区域生态空间状况有所下降的是齐河县,分布于德州市东南部;其他区县保持不变。本文对于德州市的生态保护、环境管理和可持续发展具有重要的科学和实践意义。Water bodies and vegetation are the main manifestations of ecological space, and their dynamic research is a necessary prerequisite and foundation for regional ecological construction and ecological space planning. Based on the remote sensing data of Dezhou City in 2010 and 2020, the Normalized Vegetation Index (NDVI) and Normalized Water Index (NDWI) were used as the main indicators to explore the change trend of ecological space, aiming to provide a scientific basis for ecological construction and ecological space planning in Dezhou City. The results showed that the NDVI decreased and the NDWI increased, and the regional ecological space improved. Among them, the ecological status has been significantly improved in Decheng District and Pingyuan County, which are distributed in the northwest and central and western parts of Dezhou City. The decline in regional ecological space was in Qihe County, which was distributed in the southeast of Dezhou City. The rest of the districts and counties remain unchanged. This paper has important scientific and practical significance for ecological protection, environmental management and sustainable development of Dezhou City.
