Construction of Urban Ecological Environment Detection System Based on GIS and RS Image Processing Algorithm

The essence of environmental problems is the imbalance of ecosystem caused by improper human intervention in the surrounding environment. Urban ecosystem effect embodies the accumulation of various environmental effects and is the comprehensive effect of the changes of various environmental factors. The significance of urban ecological environment evaluation lies in understanding the present situation and evolution law of regional ecological environment, discussing the fragile factors of urban ecosystem, establishing the index system and evaluation method of ecological environment evaluation, evaluating the quality and development trend of regional ecological environment, and providing theoretical basis for the protection and restoration of urban ecosystem. Therefore, this paper studies the urban ecological environment based on GIS and RS (Remote Sensing) image processing algorithm, and establishes a detection system in this paper. The functions of urban ecological environment monitoring and evaluation involved in the system can be completed under the same interface, with complete functions and convenient operation. Through GIS and RS image processing algorithms, we can also predict the source of pollutants, predict the change of water quality, calculate water level and flow, calculate water quality and nutrients, etc. These are logical attribute calculations. It is of practical significance to strengthen the protection of ecological environment and the sustainable development and ecological construction in this area.
