黄土高原的综合治理,必须坚持林草措施与工程措施相结合。而坡面田间工程措施主要是修梯田。作者从对甘肃省黄土高原的综合考察和典型分析中表明,梯田不仅具有明显的增产、增收效应,而且具有显著的蓄水、拦泥、促使土壤生态系统逐渐向良性循环转化的生态效益,在抓种树种草的同时,必须加强梯田建设,才能逐步调整农业生产内部结构,发展多种经营,建立高效能水土保持综合防护体系。
The comprehensive management of the Loess Plateau must adhere to the combination of forest and grass measures and engineering measures. The slope field engineering measures are mainly to repair terraces. The comprehensive investigation and typical analysis of the loess plateau in Gansu Province show that the terraces not only have obvious effects of increasing production and increasing income, but also have remarkable ecological benefits of impounding, While grasping trees and grasses, we must strengthen the construction of terraces in order to gradually adjust the internal structure of agricultural production, develop diversified operations and establish a comprehensive high-performance water and soil conservation system.
