摘要
研究区位于西宁甘河滩工业园区上游.随着经济的快速发展,区内河砂乱采、乱挖问题日益严重,采砂活动对整个甘河沟地质环境的破坏程度十分严重,对地形地貌造成破坏、对土地资源造成损毁,引发河道堵塞、排水不通畅、河水向两侧侵蚀冲刷等地质环境问题.本文通过调查、对比与研究地质环境现状,将研究区划分为 13个治理区,根据 13处治理区不同的损毁程度和地质环境问题等因素,对整个甘河沟从上游至下游排水条件进行统筹考虑,提出"覆坑平整+疏浚河道+加固岸墙+覆土绿化"的治理方案.通过对甘河沟采砂区的生态恢复治理,缓解因采砂而产生的一系列生态环境及地质灾害问题,逐步达到人与自然的和谐发展.
Abstract
The study area is located in the upstream of the Ganhetan Industrial Park in Xining.With the rapid development of economy,the problem of indiscriminate mining and dredging of river sand in the area has become increasingly serious.he damage of sand mining activities to the geological environment of Ganhegou is very serious,which causes damage to landforms and land resources,and causes the geological environment problems such as blocked river channel,unsmooth drainage,erosion and scouring of river water to both sides.Through investigation,comparison and study of the current status of the geological environment,the study area is divided into 13 treatment areas in this paper,and according to the different degree of damage and geological environmental problems in the 13 treatment areas,the drainage conditions of the entire Ganhegou from upstream to downstream are considered in an integrated manner,and a treatment plan of"Pit leveling+river dredging+shore wall reinforcement+soil greening"is proposed.Through the ecological restoration of sand mining area in Ganhegou,a series of ecological environment and geological disaster problems caused by sand mining are alleviated,and the harmonious development between human and nature is gradually achieved.
