摘要
河道综合治理工程水土流失主要受自然因素影响,每年集中的降雨多以暴雨形式出现。疏松土壤结构,影响高垦指数,降低林草植被率等。从侵蚀外部营力和内在侵蚀源分析,都极易产生水土流失。随着经济社会发展,人为因素在诱发土壤侵蚀成因中比重越来越大,频繁的人类经济社会活动,包括不合理土地利用以及建厂、修路等活动,都在一定程度上破坏了原有地表植被,极易造成新的人为水土流失和危害。文章结合实际阐述了河道综合治理工程水土流失的具体预测时段及预测结果,值得类似工程的参考和借鉴。
Water and soil loss of comprehensive river control project is mainly affected by natural factors.The annual concentrated rainfall mostly occurs in the form of rainstorm.It will loosen soil structure,affect high reclamation index,reduce forest and grass vegetation rate,etc.From the analysis of external forces and internal sources of erosion,it is very easy to produce water and soil loss.With the economic and social development,the proportion of human factors in the causes of soil erosion is increasing.Frequent human economic and social activities,including unreasonable land use,plant construction,road construction and other activities,have destroyed the original surface vegetation to a certain extent,which is very easy to cause new man-made soil erosion and harm.Combined with practice,this paper expounds the specific prediction period and prediction results of water and soil loss in the comprehensive river control project,which is worthy of reference for similar projects.
