摘要: 西北干旱内陆河流域水资源是联系生态系统和经济系统的纽带,从生态经济的角度,给出了水资源承载力的概念.在总结水资源承载力的特点和研究方法的基础上,将水资源承载力的研究纳入了生态经济系统的背景下进行综合集成研究.以黑河流域中游为例,提出了研究水资源承载力的多目标模型和纳入生态价值模块的途径和方法,从价值量的角度对流域生态系统和经济系统进行了初步的耦合研究,并根据模型的优化分析结果分析了未来20a黑河流域张掖地区的水资源承载力。

Abstract: Based on former research, the concept of carrying capacity is defined from the view of ecological economics. New concept’s characteristic has been investigated to provide an improved understanding about its contribution to solve environmental and resources problems.The carrying capacity of regional water resources is embedded in the macro-economic system, and multiple objective analysis technique is developed in the basis of integration of economy, society, environment, population and water resources systems. The carrying capacity model of water resources in Heihe River watershed consists of seven sub-model, i.e., macro-economic model, population model, land resources subject model, water resources development and utilization model, water environment model, water project investment model and ecological value model. In the integrated process of ecological and economic system, the comprehensive framework of development of environmental capacity during planning period is introduced. Based on previous research, the environmental capacity lost due to current and previous human activity is calculated, and then environmental adjusted GDP (EDP) is gotten by deducting environmental cost from GDP and taking the EDP as an objective of multiple objective models instead of former GDP.Through operation of the multi-objective model, the carrying capacity of water resources in Zhangye Prefecture is analysis in detail.Finally, the calculated results of the model show that: water resources development and utilization situation is worse and worse as economy grows and population pressure increases. The main thing in future is to save water resources by economical use with a view to accelerating economic growth. At the same time, the current model’s disadvantages are identified. Without a systematic, quantitative, structured relationship between the environment and the economy, it is hard to know what are the various economic contributions to environmental damage, and how the damage might be remedied. In methodology, integrated environmental and economic accounting can be regarded as a necessity in the further research.

Key words: carrying capacity of water resources, multi-objective analysis, Heihe River watershed, ecological valuation.
