摘要
生产建设活动导致生产建设项目区土壤侵蚀发生深刻变化,生产建设项目区土壤侵蚀的研究对于区域土壤侵蚀控制,改善项目区及其周边地区生态环境具有重大意义;因此,生产建设项目区土壤侵蚀的研究亦应形成其完善的理论体系,从而为生产建设项目区的土壤侵蚀控制提供科学指导。从生产建设项目土壤侵蚀的基本概念、影响因素、产流产沙规律等方面总结生产建设项目土壤侵蚀的研究现状,并对研究中存在的部分问题进行评述,以期为今后生产建设项目区土壤侵蚀的相关研究提供参考。
Production and construction activities have led to profound changes in occurrence of soil erosion newly arising in production and construction areas.Studies of basic issues in soil erosion are of great significance to sediment control and improvements of on-site and surrounding ecological environment.Therefore,theories and methodologies should be developed to provide scientific guidance for erosion control and soil ＆ water conservation planning in production and construction project areas.This paper summarizes the present research status of soil erosion in production and construction project areas from various aspects including basic concept,research methods,influencing factors,laws of runoff and sediment production; meanwhile,we analyze some of the problems in previous studies,looking forward to supplying reference for studies of related fields in the future.
