西藏自治区公路建设水土流失特点及防治措施

摘要

The Tibet Autonomous Region is high altitude and poor climate, and the vegetation cycle in the Tibet Autonomous Region is long, the vegetation restoration is very difficult, so the vegetation coverage rate is low, which resulted in the water and soil loss in Tibet Plateau is serious, so the conservation implementation of water and soil loss in Tibet Plateau is difficult. The influence scope is wide and the surface disturbance is strong during the highway construction, so it is very important to improve water and soil conservation in the Tibet Autonomous Region.%西藏自治区海拔高，气候差，植被恢复难，西藏高原形成的植被，植物生产周期长，再生能力差，植被覆盖率较低，造成了西藏高原容易造成水土流失，不容易有效治理的特点。由于在公路建设过程中，具有影响面积广、地表扰动强等特点，因此，在西藏自治区作好水土保持工作尤为重要。
