城市水系统的可持续管理

The sustainable administration for urban water system

城市水系统是在一定地域空间内,以城市水资源为主体,以水资源的开发利用和保护为过程,并与自然和社会环境密切相关,且随时空变化的动态系统。从管理角度来看,城市水系统属于城市公用事业范畴,是受政府监管而非完全竞争的产业,具有自然垄断、产品不可替代、生产连续、社会服务、适度超前等特性。随着社会的发展,城市水系统面临着人口增长、水价上升、规则增强等方面的挑战。为提高管理水平,需要采用系统论方法,总体考虑社会、经济和健康因素,将可持续发展的概念融入到城市水系统的管理中。

Urban water system is defined as a dynamic system in which it takes the urban water resources as main body, takes the water utilization and protection as progress, and takes the nature and society as one unit. From the point of view of administration, the urban water system is one part of urban public facilities, and is supervised by government but is not completely competitive industry. It is characterized by natural monopoly, non -replacement, processes uninterrupted, etc. Now there are a number of key challenges to urban water system in all towns and cities, such as fast urbanization, population growth, water price rising, etc. So, it proposes that the concept of sustainability needs to be integrated into urban water system administration in order to improve level of administration.
