| 摘要: |
| 流域是自然形成的水动力系统,流域管理是以水资源为中心的科学管理管理"是用法律、规范、条例、办法等来实现的,而流域是复杂的系统,具有整体性、动态性、耗散性, 同时它是人类赖以生存的资源环境.因此流域管理就应该顺应河流流水的动态变化.长江流域的管理是一项系统工程,应坚持以综合管理为根本、以科学预测为基础、以降低熵值为目标、以环境安全为核心.即在坚持整体综合全面统筹的前提下,其治理和开发必须以科学预测为基础,尤其是洪涝灾害的治理应该有中长期的灾害预测作为启动治理工程的根据;同时管理的目标是降低系统熵值以加大系统稳定性和有序性;还有长江流域管理的核心任务是流域环境安全,以保证流域经济、社会和生态的可持续发展. |

| Abstract: |
| Watershed management is scientific management focusing on water resource. Management is realized by means of laws, criterions, byelaws, means and so on. Watershed is a complicate system which has some characteristics such as integer, dynamic, dissipative etc., and it is important resources environment to human kind. So watershed management ought to pay attention to the variance of every component in watershed. The Yangtze River watershed management is a systems engineering. In the process of its management, we must persist in integrative management as root, scientific forecasting as base, reducing entropy value as object, environmental safety and security as kernel task. The preconditions on the synthesis analyzed of watershed components, repairing and exploitation watershed ought to base on scientific forecasting. Especially we should base on the mid-long-term disaster forecasting in start-upping floods impairment project. Reducing entropy value can increase system5s stability and ordering, and ensuring the environment safety and security can guarantee sustainable development of economy, society and ecology of watershed. |
