Abstract

Urbanization and the ecological environment have a long-standing, mutually constraining relationship. A healthy ecological environment is the natural basis for human society's survival and an important indicator of urbanization. Therefore, an accurate assessment of urban ecology is of vital significance. Remote sensing technology has natural advantages over traditional urban ecological quality assessment methods, such as high efficiency, timeliness, and comprehensive coverage. This paper aims to introduce the application of remote sensing technology in urban ecological evaluation, focusing on both single and comprehensive indices. The method for processing remote sensing indices involves combining captured electromagnetic waves with specific bands to form remote sensing indices. These indices are then analyzed to evaluate urban ecological conditions, including monitoring urban vegetation and evaluating urban development. The research trend of optimizing data sources and improving index construction is also discussed. This paper demonstrates the feasibility of using processing method of remote sensing index for urban ecological evaluation. It provides decision makers with valuable information and offers technical support for promoting sustainable urban development.
