Intelligent evaluation system and method for ecological function of soil

Abstract

The invention discloses an intelligent evaluation system and method for a soil ecological function, and particularly relates to the field of environmental science, and the system comprises a multi-source heterogeneous data collection layer, a multi-dimensional index resolving engine, a multi-cascade analysis controller and an intelligent evaluation module. According to the method, a nonlinear cascade analysis model is innovatively constructed, the ecological phase change critical point is accurately recognized through structure-biology-environment multi-dimensional coupling calculation, the ecological collapse early warning sensitivity is effectively improved, a dynamic checking mechanism is introduced to achieve chemical stress and structure degradation composite action analysis, the limitation of parameter isolation analysis of a traditional method is broken through, and the method is suitable for large-scale popularization and application. A progressive toughness diagnosis architecture is adopted to fuse real-time monitoring data, a space-time continuous evaluation system is established, the diagnosis universality under different environmental conditions is remarkably enhanced, and accurate decision support is provided for ecological restoration.
