摘要
梯田断面的设计保证了梯田功能的实现和运行,学界对于梯田断面各要素之间的关系和约束条件观点不一,加上各地需要和客观条件差异,在梯田断面设计和优化思路上缺乏统一的认识,为梯田的科学化修筑,坡改梯政策施行的效果埋下了隐患。本文综合分析各学者在梯田断面设计上的参考因素和计算方法,在分析优劣得失的基础上为梯田断面设计的优化思路建立科学、统一的认识。
The proper cross section design ensures the function of terrace. Scholars have different viewpoints for designing cross section of terrace, because of local needs and individual considerations. There are no unified viewpoints and standardized design methods for terrace cross section which may cause hidden problems. This paper compares and analyzes differrent methods and tries to build up an optimal method to design cross section of terrace.
