【摘要】：水土流失灾害是我国严重的地质灾害之一,严重威胁经济建设与人民生命财产安全,急需治理。金堆城北部排土场由于接受矿区弃土弃渣,加上人为活动剧烈,给原地貌造成了严重的破坏和扰动,为此本文进行分析研究,通过分析金堆城北部排土场水土流失灾害现状,研究其分布和侵蚀规律,为科学合理的治理措施提供依据。本文主要得到以下结论:1、根据现场调查和勘察综合分析,北部排土场地表植被受到严重破坏,水土流失灾害状况相当严重。2、通过对岩性、冲刷量和覆盖率的分析,得出覆盖率对防治水土流失灾害起主要作用。3、排土场水土流失灾害主要发生在坡面,岩性较破碎且风化程度越高的部位侵蚀沟越明显。4、侵蚀规律的时间、空间分布明显,主要发生在多雨季节,且侵蚀沟中部一般比较深,上部比较细小,整个形态交叉又合并,在坡面下部形成扇状堆积物。
[Abstract]:Soil erosion disaster is one of the serious geological disasters in China, which seriously threatens the economic construction and the safety of people's life and property, and is in urgent need of management. The dump in the northern part of Jinduicheng has been seriously damaged and disturbed by the acceptance of the abandoned soil and the waste residue of the mining area and the intense human activities. Therefore, this paper analyzes and studies the present situation of the soil and water loss disaster in the northern dump of Jinduicheng, through the analysis of the current situation of soil and water loss. The study of its distribution and erosion law provides the basis for scientific and reasonable control measures. The main conclusions of this paper are as follows: 1. According to the field investigation and comprehensive investigation and analysis, the vegetation on the surface of the northern dump has been seriously damaged, and the situation of soil and water loss disaster is quite serious. 2. Through the analysis of lithology, scour amount and coverage, The results show that coverage rate plays a major role in the prevention and control of soil erosion disasters. 3, soil erosion disasters in dump mainly occur on the slope, and the erosion trenches in the areas where the lithology is relatively broken and the degree of weathering is higher are more obvious. 4, the time of erosion law, The spatial distribution is obvious, mainly occurred in rainy season, and the erosion ditch is generally deep in the middle, the upper part is smaller, the whole form is crossed and merged, and the fan-shaped deposits are formed in the lower part of the slope.
