- Abstract:
- Systematic and scientific evaluation of the ecological benefits of land remediation has a positive impact on agricultural ecological protection and agricultural landscape construction. From the perspective of ecological landscape, combining with the characteristics of land remediation and engineering practice, analytic hierarchy process is adopted to develop the ecological benefit evaluation system of land remediation from three aspects: basic function, ecological engineering energy and landscape function, and the weight coefficient of each level is determined. Taking the ten thousand mu paddy field in Qujiang and the land reclamation of Baihetan as examples, and based on the preliminary evaluation results obtained by AHP, a back propagation neural network model was designed and applied to the case by training and testing. The results show that the evaluation values of basic, ecological, landscape function and ecological benefits of Baihetan(Yunnan), Baihetan(Sichuan)and Qujiang are 57.73, 82.63 and 85.43; 61.62, 57.11 and 65.08; 40.83, 43.29 and 52.11; 52.92, 56.84 and 64.10, respectively. The analysis shows that Qujiang is superior to Baihetan in terms of overall ecological benefits and functions. The AHP-BP model combines the characteristics of subjective optimization and objective mapping to make a systematic and scientific evaluation of the ecological benefits of land remediation, and the evaluation results are consistent with the actual situation, indicating that the method is feasible and effective and can provide reference for the ecological benefit evaluation of land reclamation in different regions.
