嘉陵江水资源分析
|
摘要
人类活动和气候变化对径流的影响日益加剧,进而影响流域水资源量。流域水资源是工业生产和居民生活的重要资源,因此对变化环境下流域水资源进行分析具有重要意义。本文对嘉陵江流域进行水资源分析。结果表明,略阳水文站水资源量呈减少趋势,武侯水文站水资源量趋于平稳。略阳水文站径流演变存在3～8年、15～30年尺度的周期变化规律;武侯水文站径流演变存在3～8年、20～30年尺度的周期变化规律。
The effects of human activities and climate change for streamflow are increasing aggravation, which further affects water resource quantity in the basin. Watershed water resources are an important resource for industrial production and residents' lives. Therefore, it is of great significance to analyze water resources in a basin under changing circumstances.This paper will analyze the water resource in Jialing River Basin. The results show that water resource at Lueyang station has decrease trend and water resource at Wuhou station tend to be stable. The runoff evolution of Lueyang hydrological station has periods of 3 ～ 8 years and 15 ～ 30 years.The runoff evolution of Wuhou hydrological station has cycles of 3 ～ 8 years and 20 ～ 30 years.
