多源遥感数据支持下的城市生态状况评价

Assessment of the urban ecological status based on multi-source remote sensing data

城市生态环境监测具有数据来源广泛、监测要素复杂、服务对象多样等特点,整合可用的资源进行城市生态的综合监测成为目前关注的热点。本文利用高分辨率遥感影像,以及地表覆盖、城市边界等遥感产品,在现有遥感生态指数的基础上,结合黑臭水体指数,构建适合综合评估城市生态状况的集成遥感监测模型,实现对城市生态环境状态的多维度监测。该方法能够较准确客观地反映城市的生态环境质量,理论上补充了基于遥感数据的城市生态环境监测方法,可为城市生态环境监测的信息化建设提供技术支撑。

Urban ecological environment monitoring has the characteristics of multiple data sources, complex monitoring elements, and diverse service objects. How to integrate available data resources for comprehensive monitoring of urban ecology has become a research focus. This article attempts to use high-resolution remote sensing images combined with remote sensing products such as fine classified global land cover and urban boundaries. Based on the existing remote sensing ecological index(RSEI), combined with the black and odorous water index, an integrated remote sensing monitoring model suitable for comprehensive assessment of urban ecological conditions is constructed to realize the comprehensive monitoring of the state of the urban ecological environment. This method can more accurately and objectively reflect the quality of the city’s ecological environment, theoretically supplements the urban ecological environment monitoring method based on remote sensing data, and provides technical support for the information construction of urban and rural ecological environment monitoring.
