【摘要】 我国西北地区是资源型缺水地区,对水资源进行科学、有效的管理无疑是该地区可持续发展的核心问题之一。在分析了生态系统管理的概念、特点、对于自然资源管理的意义,以及影响西北地区水资源安全性的生态学原因之后,提出了西北地区确保水资源安全的生态系统途径。包括:建立以流域为单元的水资源生态系统管理模式;充分利用市场机制,完善水资源管理模式;以水资源承载力和水资源安全为基础,进行西北地区的生态环境建设;加强水生态环境管理,避免因水污染造成更加严重的水危机。更多还原

【Abstract】 Northwest China is short of water resources and sustainable development there depends on the rational and effective management of limited water resources. Based on the analysis of concept, features of ecological management and its significances to natural resources management together with water security in Northwest China viewing from ecological angle, some ecosystem approaches to assure water security in Northwest China were proposed which include: (1) to set up a new ecosystem management model of water resources taken the watershed as an unit; (2) to fully use market adjustment mechanism so as to perfect the water resources management; (3) to take the water resources capacity and water security as the base of ecological restoration and construction; and (4) to emphasize the water ecoenvironment so as to avoid more severe water crisis caused by water pollution.更多还原
