摘要:

为了实现城市水系统的健康循环及人类社会的可持续发展,从生态学的观念出发利用系统科学的分析方法,对自然资源的循环规律、人与自然关系的思想根源以及追求经济发展的传统生产方式的弊端进行了系统全面的论证,对水危机的根源进行了深刻的剖析.提出了传统排水系统功能、水资源利用模式的变革以及社会用水健康循环和水环境恢复的方略.指出只有把握和利用自然规律,将人类的生产与生活活动限定于自然生态平衡之中,才能维护生态系统的平衡实现可持续发展.

Abstract:

In order to achieve the healthy cycle of urban water system and the sustainable development of human society,the root of the crisis of water was analyzed. Starting from the concept of ecology with scientific analysis method,the cycle law of natural resources,the ideological roots of the relationship between human and nature,and the disadvantages in pursuiting economic development with traditional production modes were demonstrated. Strategies are put forward for the changes of the function of traditional drainage system as well as the patterns of water use,and for the healthy cycle of social water and the water environment recovery. By grasping and using the laws of nature,limiting human activities in a natural ecological balance,the balance of ecosystems can be maitained and sustainable development can be achieved.
