摘要:
[目的] 明确不同山丘区输变电线路工程水土流失特征,为山丘区水土保持设计、监测和防治提供理论参考。[方法] 以全国不同山丘区(东北黑土低山丘陵和漫岗丘陵区、西北黄土丘陵区、南方红壤丘陵区、青藏高原区、新疆山地区)输电线路工程为研究对象,通过文献查阅、野外调查并结合工程实例,对山丘区输变电线路工程水土流失来源、影响因素及措施体系配置进行归纳和总结。[结果] 输变电线路工程主要水土流失来源分区可分为站区、道路区、临时堆置区、塔基区、牵张场区和弃土弃渣堆置区;输变电线性工程水土流失具有不均衡性,其中站区占水土流失量的比例最高,达总水土流失量的48%~62%,其次为塔基区,其主要来源时段为施工期。[结论] 不同山丘区水土流失影响因素和防治重点差异显著,水土保持设计时须考虑土壤侵蚀形式的差异,并因地制宜地配置水土保持措施。

Abstract:
[Objective] The characteristics of soil and water loss of different types of power transmission line projects (PTLPs) in hilly and mountainous regions were explored to provide a theoretical reference for the design, monitoring, and prevention of soil and water loss. [Methods] PTLPs in hilly and mountainous regions (low-elevation mountains and hills of Northeastern China, hilly loess region of Northwestern China, hilly region of Southern China, the Qinghai-Tibet Plateau, and the Xinjiang hilly region) in China were taken as the study object. Based on literature review, field investigations and engineering examples, the sources, influencing factors, and controlling measure configurations of soil and water loss in PTLPs of hilly and mountainous regions were studied. [Results] The main sources of soil and water loss in PTLPs could be divided into station area, road area, temporary stacking area, tower area, stretch field area and slag stacking area. The soil and water loss of the PTLPs was spatially variable. The station area accounted for the highest proportion of soil and water loss, which was up to 48%~62% of the total soil and water loss, followed by the tower area. The main source period was the construction period. The influencing factors of soil and water loss and the key points of prevention in the hilly and mountainous regions were significantly different. [Conclusion] There are significant differences in influencing factors and key points of prevention and control of soil and water loss in different hilly areas. Different forms of soil erosion should be considered in the design of soil and water conservation, and the allocation of controlling measures should be adapted to the local conditions.
