However, the technical scheme is to evaluate the ecological environment based on the existing data, so that the influence of engineering on the environment is difficult to evaluate simply and intuitively, and the situations that the single index exceeds the standard and the single index is not out of the standard but has larger overall influence are difficult to distinguish.
The Chinese patent with publication number of CN113592267A discloses a project environment influence evaluation auxiliary analysis system, and particularly discloses an environment influence evaluation analysis module which is used for realizing the current area environment influence evaluation analysis based on the environment influence evaluation auxiliary analysis model. However, the prior art fails to numerically evaluate the influence of the project on ecology, and is difficult to distinguish the situations that the single index exceeds the specification and the single index is not over-specified but has larger overall influence.
