基于AHP与RAGA-PPC的田间灌排渠道工程优化研究

The optimization of the field irrigation channel project based on AHP and RAGA-PPC

为了从理论与实践两方面探讨灌排两用沟渠的优越性,文章以石佛寺灌区为研究对象,拟定三种不同渠系规划方案进行对比分析。利用RAGA-PPC模型对拟定的方案进行优选,结果显示灌、排流向同向的灌排两用渠道设计为最佳方案。RAGA-PPC模型为该领域研究提供了新思路,可以农田灌溉工程设计的理论依据。

In order to discuss the superiority of the dual-use irrigation and drainage ditches in both theoretical and practical way,this paper uses Stone Buddha Temple as the object of the research,and carries out the contrast analysis to three different canal system planning.RAGA-PPC model is used to optimize the drafted plan,the result shows that dual-use irrigation and drainage irrigation and drainage channel design flow in the same direction is the best solution.RAGA-PPC model provides a new idea for the research in this field,and it can be used as the theoretical basis of farmland irrigation engineering design.
