Evaluation model of ecological economic benefits based on discrete mathematical algorithm

In this this paper, an evaluation index system was constructed to standardize the evaluation index of ecological economic benefit considering the principles of scientific, concise, systematic, dynamic, consistent, and calculable. According to the objective and fuzzy practical judgment of the evaluation object, the hierarchy structure of the index system was constructed. Principal component analysis was used to calculate the weight value of the first-level index. Analytic hierarchy process (AHP) was incorporated to calculate the weight value of the second-level index. The nonlinear coupling was qualitatively analyzed between social economic benefits and ecological environmental benefits using Lyapunov first-party method. The influence coefficient of each subsystem was introduced into each subsystem by discrete data algorithm to evaluate the ecological economic benefit, and the ecological economic benefit evaluation model based on discrete mathematical algorithm was constructed. The experimental results showed that the cost evaluation results based on the benefit evaluation model designed in this paper have a slight error, and the ecological economic benefit evaluation results have high accuracy.
