印度地埂技术理论与实践——等高地埂Theory and practice of Indian bunding technology: contour bunds
宋春雨
摘要(Abstract)：
地埂是相比于梯田建造成本更低,作业更简单的防止水土流失的工程措施。地埂技术大范围、大规模的应用主要集中在非洲、印度和中国。与中国、非洲相比,印度在地埂技术设计原理、实践应用方面做了更多的工作。通过对文献资料、视频讲座及网页宣传资料等的整理,本文详细介绍了印度的地埂技术应用现状和设计原理,重点阐述了等高地埂垂直/水平间距、地埂埂高和截面积等重要参数的计算,实例分析了田间施工操作,以期对中国今后在地埂技术的设计、推广应用方面有所启发和推动。
