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

doi:10.13474/j.cnki.11-2246.2021.331

Abstract

Abstract: 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.

Key words: high-resolution remote sensing images, urban ecology, remote sensing monitoring model, information construction
