Evaluation of urban ecological security model based on GIS sensing and MCR model

Urban ecological security is not only a basic safety requirement for human security and development, but also an important part of national security and other security and infrastructure carriers. Protecting the environment is an important factor in the construction of China's natural civilization. In recent years, with the deterioration of the environment, the region and its people have paid more and more attention to the safety of urban ecological environment, which has become one of the hottest issues in current research. Land use/cover rate change (LUCC) affects the environment, which will also affect environmental safety, and changes in its appearance will also affect nature and the environment, providing a positive impetus for the control of natural processes. In this paper, researches on the above problems in City K and Zhengzhou are carried out, using MSPA and visual image forms to better connect local resources, and through the MCR model based on ecological control, a weight-based multi-structure network model is established, which is conducive to the establishment of a multi-structure network model based on ecological control. Build a city of environmental science network. The GIS control line was explored, and the concept of the control line was filled to a certain extent. At the same time, taking City K and Zhengzhou as examples, determining the breadth of their layout and management, as well as the control strategy of their environmental control lines, provides a specific reference angle for the layout and research of other cities. Urban ecological security is very important to each of us living in cities. It is a difficult problem at this stage to establish an ecological security model to open a new security pattern.
