摘要:
[目的] 总结分析当前崩岗治理技术措施研究现状,为制定更为合理的崩岗防治策略提供参考。[方法] 通过文献查阅,根据崩岗的空间结构特征,分别从集水坡面、崩壁、崩积堆、沟谷和冲积扇等方面系统性地总结了针对不同部位的崩岗治理技术措施。[结果] 总结探讨了不同技术的特点、适用性以及存在的问题,对崩岗的不同治理模式进行了归纳,并对未来崩岗治理技术的研究方向进行了展望。[结论] 工程与生物技术相结合的修复方式是目前采用最广泛的治理措施。今后的崩岗治理工作的开展应注重修复效果评价指标体系构建、水土保持作用机制、创新修复技术应用、修复技术与农业生产相结合以及预防措施等方面的研究。

Abstract:
[Objective] This paper aimed to review existed collapsing gully control techniques in order to provide some theoretic references for making more reasonable collapsing gully restoration strategy.[Methods] By reviewing related literatures, and based on the spatial structure characteristics of collapsing gully, this paper reviewed the presently practiced collapsing gully control techniques, systematically summarized the control techniques for different parts of collapsing gully from the aspects of catchment slope, collapsing gully wall, collapsing gully pile, flow channel and alluvial, as well.[Results] The characteristics, applicability as well as the problems of these techniques were discussed. In addition, treatment models of collapsing gully were also summarized. The prospects of some directions for future collapsing gully control technique research were aslo pointed out.[Conclusion] The combination of engineering and biological technologies is the most widely used treatment measure. Future researches on collapsing gully control technique should focus on establishing assessment indicators system, exploring soil and water conservation mechanism, combining restoration tehcnology and agricultural production, developing innovative restoration technology, and prevention treatments, etc.
