Abstract: In order to overcome the problem that the urban green landscape pattern construction effect is not ideal, this paper proposes the research method of spatio-temporal evolution of urban complex landscape pattern based on remote sensing technology. This method collects landscape pattern information. Landscape images are processed by radiometric correction and geometric correction, and spatial pattern indices are calculated. The experimental results show that: under the research method of spatiotemporal evolution of landscape pattern in this paper, the landscape area of dry land is reduced more, the transfer volume of residential, industrial and mining land and water area is less, and the stability is stronger. The density of landscape edge increased, indicating that the degree of landscape fragmentation in the city has a deepening trend. In terms of landscape spatial heterogeneity, the overall pattern tends to be coordinated, which indicates that the proposed method has good application performance.

Keywords: remote sensing technology; landscape pattern; temporal and spatial evolution.
