云南小型露天采石场水土保持措施设计新思路

New Ideas on Design of Soil and Water Conservation Measures for Small Open Quarry in Yunnan Province

摘要: 云南省的小型露天采石场数量多、水土流失严重、水土保持难度大，传统的以功能分区进行防治措施设计容易出现重复和遗漏，措施体系复杂使得建设单位难以掌握落实。本文提出以土壤侵蚀原理为基本出发点，以防治水土流失为首要目标，按照“消除侵蚀营力、稳固地表物质、保护水土资源、恢复生态、加强管理”的设计思路，以排水设计为首要重点，逐项设计水土保持措施。设计思路和设计措施供同类项目参考使用。

Abstract: Small open quarry is very common in Yunnan Province with serious soil erosion and hardly soil & water conservation control. Duplication and omission often are found in control measures by using the traditional functional zoning, and complex measures system makes the construction units hard to implement. The basic starting point on the principle of soil erosion is proposed in this article with the primary goal of soil erosion control. According to the design idea of “erosion force eliminated, soil surface material fixed, soil and water resources protected and ecological restoration, and management strengthen”, drainage design was taken as the primary focus, then the other soil & water conservation measures was designed item by item. Design ideas and measures could be reference for similar projects.
