摘要:
黄土高原多沙粗沙区高强度产沙是自然因素和人文因素综合作用的结果.该产沙过程对其影响要素存在着多个维度的临界响应.在对多沙粗沙区侵蚀产沙影响要素进行识别的基础上，比较系统地阐述了该地区侵蚀产沙存在的自然临界和社会经济临界问题及其产生的内在机理，以便为该地区的水土流失治理和生态环境建设提供一定的理论和调控依据.
Abstract:
The high intensive sediment yield in the area with abundant and coarse sediment of the Loess Plateau results from the joint action of natural and human factors,and there are multi-dimensional threshold in the process of sediment yield.From the threshold perspective,the authors systematically analyzed the natural and socio-economic threshold problems existing in the sediment yield process and their intrinsic mechanisms in order to lay some theoretical foundation for the harness of water and soil conservation and improvement of ecological environment in this area.
