目前,我国生产建设项目较多,对地表的扰动面积较大,若不实施好水土流失防治措施,对生态环境的影响相当大.因此,我们在从事水保监测工作的过程中,应该注意总结,根据项目区所在地理位置特性、气候特点及研究项目区土壤侵蚀特性,有针对性地提出防治措施及建议,尽可能地降低项目建设所引起的水土流失量.本文主要以云南省镇雄县朱家湾煤矿建设项目为例,根据本工程项目在建设过程中的水土保持监测数据,对该项目各监测时段内的土壤侵蚀量的变化情况进行分析,总结风化破碎带地区在冻融侵蚀影响下的土壤侵蚀量变化特性.
At present, there are many production and construction projects in our country, which have a large disturbance to the surface. If we do not implement the prevention and control measures for soil and water loss, the impact on the ecological environment is quite large. Therefore, we should pay attention to the summary in the process of monitoring the soil and water conservation , According to the characteristics of the geographical location where the project area is, the climate characteristics and the soil erosion characteristics of the research project area, put forward the prevention and control measures and suggestions pertinently to reduce the amount of soil and water loss caused by the project construction as much as possible.This paper mainly takes Zhenxiong County Taking Zhujiawan coal mine construction project as an example, according to the monitoring data of soil and water conservation during the construction of this project, the change of soil erosion in each monitoring period of the project is analyzed, and the influence of freeze-thaw erosion on weathering and crushing zone is summarized Soil erosion under the changing characteristics.
