Remote sensing big data-based regional ecological safety early warning and forecasting method

Abstract

The invention discloses a remote sensing big data-based regional ecological safety early warning and forecasting method. A remote sensing big data monitoring module obtains real-time monitoring data of a monitored region of a basin; an information preprocessing module obtains characterization data capable of characterizing a water ecological safety condition of the monitored region of the basin; an index system management module obtains a weight value of the real-time monitoring data; a model management module performs early warning management and analysis; a water ecological comprehensive evaluation module builds a water ecological risk probability index model, a water ecological loss degree index model and an evaluation unit-oriented water ecological risk comprehensive index model, and then performs simulation on a water ecological risk of the monitored region of the basin; and a risk pre-plan management module judges whether a risk source is a major risk source or not, and makes a processing decision. The water ecological risk early warning model is built; visual display of space distribution of easily waterlogged points is realized; and the method has very high social and economic benefits and high practical values.

Description

technical field [0001] The invention relates to an early warning method, in particular to a regional ecological security early warning and forecast method based on remote sensing big data. Background technique [0002] Watershed is a kind of complex natural geographical area, which is a comprehensive ecology that closely connects natural support systems such as water cycle, land cover, ecosystem, and socioeconomic systems such as population, economy, and society with surface water and groundwater as the main link. territory system. In the existing related technologies, water quality monitoring equipment is often used to monitor the water quality of a certain watershed monitoring area, specifically: a certain amount of water samples are taken out from the watershed monitoring area by the staff, and then water quality analysis equipment is used to analyze the water samples taken out. Analysis, so as to judge the water quality of the monitoring area. This method has the probl...

Problems solved by technology

The existing method of finding waterlogging spots is mainly manual field survey, which not only consumes a lot of manpower and material resources, but also has low efficiency, and it is impossible to quickly track the changes of waterlogging spots caused by urban construction, and it is also impossible to intuitively obtain the space of waterlogging spots Therefore, it is difficult to quickly release early warning information of water damage points, causing troubles and losses to urban residents' traffic travel and their lives and properties
