我国生活水循环系统的分析与调控策略

在对生活用水的基本内涵、特性以及影响因子进行分析的基础上，对三大典型生活用水单元即农村、城镇与发达城市生活用水单元的水循环结构进行了解析。通过对国内外生活用水系统的调研，从通量、结构、质量等方面归纳了生活水循环的发展规律。在此基础上，提出了我国生活水循环的调控目标，并对基于水质水量耦合的多元优化调控途径进行了探索。

Domestic water cycle system and its regulatory strategies in China

The connotation, characteristics and influencing factors of domestic water use are analyzed. On this basis, the structures of water cycle for three typical patterns of domestic water use including the rural domestic water use, urban domestic water use and metropolitan domestic water use are discussed. According to the investigation on the existing domestic water cycles both in China and in abroad, the principles of development are concluded from the view points of both quantity and quality. The objectives of regulation on domestic cycle system and the corresponding regulatory stategies based on multiple regulation approaches aiming at the target of establishing a healthy domestic water cycle system in China are suggested.
