Urban renewal design based on analysis of remote sensing images and texture characteristics

Abstract

Cities are organic organisms, and urban regeneration is accompanied by urban development, which promotes the continuous regeneration and transformation of cities. In order to pursue rapid urban development, the original intention of urban development has been ignored, leading to various urban diseases in the city, and eventually, it will lead to urban road congestion. Remote sensing information can reflect the role and influence of the urban ecological change process. Based on remote sensing image technology, with various stages of urbanization as the background, the survey was conducted based on the comprehensive response characteristics of urban elements and urban thermal environment, the relationship characteristics of the impact, and the adaptability of spatial analysis. From the perspective of urban texture, analyze the reasons for the breakage of the texture, and put forward corresponding definition methods and stitching strategies. The results show that with the advancement of urbanization, there is a large gap in the surface energy levels between urban and natural elements, and a large gap in energy between physical space and open space. Therefore, it is necessary to explore measures to solve ecological problems in terms of urban element structure combination and space allocation, and to stitch together a vibrant city with delicate urban texture from the three levels of space, function and culture.
