Abstract
Considering that the development of urbanization cannot be separated from the application of landscape pattern evolution, in order to improve the development level of ecocity, a modeling analysis of ecological urban landscape pattern evolution based on multisource remote sensing data is proposed. Taking ecotype city as the research object, the remote sensing images of ecological urban landscape pattern are screened by using multisource remote sensing data and nonremote sensing data as the basic data. CA-Markov model is constructed and the evolution of ecological urban landscape pattern is analyzed. The experimental results show that, from 2005 to 2020, the development level of urbanization process is higher and higher and the area of building land patches is increasing, which reduces the fragmentation of building land patches. However, the landscape of cultivated land and green space is less and less, and the distribution of the patches also causes uneven phenomenon, which leads to the gradual decline of ecological urban landscape diversity. In the ecological urban landscape pattern, the degree of fragmentation and diversity of urban landscape is reduced due to the high connection and coverage of the construction land.

Due to China’s vast territory and large population, energy consumption is increasing
A series of environmental pollution problems have become more and more serious. e destruction of the ecological environment has caused extreme weather such as drought and high temperature, leading to frequent occurrences of natural disasters. erefore, the protection of the ecological environment has become the primary issue to realize the sustainable development of mankind [1]
It can purify waste and regenerate the ecological environment. erefore, building an ecological urban landscape pattern is an inevitable way to achieve sustainable social development [2]. erefore, protecting the ecological environment and building an ecological city are the current focus of the Chinese government
Summary
Due to China’s vast territory and large population, energy consumption is increasing. The ecological environment in densely populated urban areas is seriously damaged, and urban green spaces, forests, and water play a decisive role in the entire ecological environment cycle. It can purify waste and regenerate the ecological environment. E urban landscape pattern is a witness to the evolution of urban development It records the traces of urban construction and reflects the overall style of the city. It is a unique perspective of urban development [5]. Based on the above analysis, this paper applies multisource remote sensing data to the modeling and analysis of the evolution of the ecological city landscape pattern, so as to improve the development level of the ecological city
