陕西省商州区地质灾害成因及防治研究

Causes of Geologic Hazards and Control in Shangzhou Region of Shaanxi Province

地处陕西省东南部的商州区是一个群山连绵,沟壑纵横,以中低山为主的土石山区,属于地质灾害易发地区,由于自然和人类工程——经济活动的诱发,水土流失比较严重,崩塌、滑坡、泥石流、地面塌陷等地质灾害时有发生。在调查分析该区地质地貌、土壤、植被、水源条件、人类活动等地质灾害成因的基础上,针对商州区实际提出了统筹规划,建立科学的防治预案,提高环境意识,加强植被保护,建设生态商州,加强土地资源的管理和可持续利用,加强矿区综合治理等防灾减灾的对策建议。

Shangzhou is located in the southeast of Shaanxi Province and characterized by widespread gullies and low mountains. It is a place where geologic hazards easily take place. Due to natural and human-induced events or processes, it is suffering from serious soil and water loss. Debris flow and ground collapse happen frequently. By investigating and analyzing the causes of geologic hazards such as landforms, soil, vegetation, water resources, and human activities, the paper gives some advices on hazard control. They are establishing a scientific prevention plan by integrated planning; strengthening vegetation protection and building an eco- logical Shangzhou by enhancing environment sense; enhancing management and sustainable use of lands; enhancing comprehensive rehabilitation of mining area.
