Abstract

The coverage, scope and regional change of urban impervious layer have an important impact on the urban ecological environment, thermal environment and hydrology. The analysis of impervious layer distribution is the premise of urbanization, which can assess the urban development planning and ecological assessment. In this paper, Landsat 8 satellite image data of 2010, 2015 and 2020 are used as the information source, the NDISI index and linear spectral decomposition algorithm are used to derive the results of urban impervious layer, and the spatio-temporal analysis and research are carried out, including the discussion of impervious layer density in the same area, and the change trend of impervious layer range. Through the analysis of the results of impervious layer, the development of impervious layer coverage rate is obtained, and the proportion of impervious layer in Zhengzhou city is obtained, so as to analyze the impervious layer in Zhengzhou city. On the whole, the impermeable layer of Zhengzhou City has an obvious trend of diffusion to the surrounding area. Through the understanding and analysis of the results, we can provide some directions for the future urban development of Zhengzhou City: to formulate scientific land use norms, to establish a scientific land use system, to establish a scientific land use system, improve the land utilization ratio, reasonable planning of urban infrastructure construction.
