近几十年来，全球平均气温的持续上升对该区域气温、降水、径流等水循环要素产生重要的影响。
Global warming brings an important impact to the water cycle factors such as air temperature, precipitation and runoff and so on in the area in the recent decades years.
同时，将流域水循环系统概化为自然水循环系统和人工水循环系统，分别用供水单元和用水单元模拟其结构构成要素。
At the meantime, it generalizes the water circulation into natural and human water circulation system using water supply and water consumption unit to simulate their structure factors.
水循环主要要素的变化取决于气候条件的变化与人类活动的影响。
The changes of water cycle elements depend closely on climate variations and human activity impacts.
