中文摘要: |
在总结分析前人研究工作的基础上,首次提出了界定生态用水须遵循的基本原则。据此,对生态用水、生态需水和生态缺水的概念进行了科学界定,并讨论分析了他们之间的相互关系;提出一套完整的生态用水的分类系统;提出水土保持、植被、城市等河道外生态用水的计算方法;以位于黄土高原地区的延安市为例,对其2001年水土保持生态用水和城市绿地生态用水进行了计算。 |
英文摘要: |
The basic principle for defining the ecological water use is proposed. On this basis the definitions of ecological water use, ecological water requirement and ecological water deficiency are defined and the relationships among them are analyzed. An integrated set of classification system for ecological water use is suggested. The method for calculating the off-stream ecological water use including the water consumptions for soil and water conservation, vegetation and urban green land is developed. The calculation of ecological water use for different purposes in Yanan City, located at the loess plateau area, is taken as a case study to demonstrate the proposed method. |
