摘要
该文主要探究低丘缓坡未利用地开发过程中农田水利工程的规划设计,并对开发方案的效益展开评价。首先介绍项目区的基本情况,以及农田水利工程的整体布局。随后分别从土地平整工程、灌溉与排水工程、农田防护与生态保持工程3个方面,概述低丘缓坡农田水利工程的规划设计要点。根据规划设计方案,运用德尔菲法构建土地适宜性评价体系,并选择田块平整度、有效土层厚度、灌溉保证度等评价指标,对项目区土地适宜性作出量化评价。结果表明,综合分值为80分,项目区土地适宜耕种,在提供配套水利工程的基础上能够产生良好的经济效益。
This paper mainly probes into the planning and design of farmland and water conservancy projects in the process of unused land development on gentle hills,and evaluates the benefits of the development scheme.First of all,the article introduces the basic situation of the project area and the overall layout of the farmland and water conservancy project.Then,the main points of planning and design of low hilly gentle slope farmland water conservancy project are summarized from three aspects:land leveling project;irrigation and drainage project;and farmland protection and ecological conservation project.According to the planning and design scheme,the land suitability evaluation system is constructed by Delphi method,and the evaluation indexes such as field smoothness,effective soil thickness and irrigation guarantee degree are selected to quantitatively evaluate the land suitability of the project area.The results show that the comprehensive score is 80,and the land in the project area is suitable for farming,which can produce good economic benefits on the basis of providing supporting water conservancy projects.
