Research on Extraction and Evaluation of Ecological Corridor Based on Remote Sensing and GIS

With the acceleration of urbanization, the impact of human activities on the ecological landscape pattern has become more and more serious. The contradiction between population, resources and ecological environment become more noticeable. The monitoring and evaluation of urban ecological pattern is of great significance for sustainable development, and provides decision-making basis for urban construction department on ecological construction and urban and rural planning.The ecological corridor between the ecological control lines is a region with relatively severe changes. The establishment of an ecological corridor is important for landscape ecological planning, and it is an important measure to solve the landscape fragmentation caused by the current human activities and the numerous environmental problems.In this paper, we use high-resolution remote sensing satellite data, combined with the ecological community classification method of projection pursuit, taking Shenzhen as an example, effectively construct the ecological corridor landscape index, analyze the corridor function, and evaluate the importance of various ecological corridors. The research results provide a scientific guide for urban planning and ecological protection.
