摘要

西北干旱內(nèi)陸河流域水資源是聯(lián)系生態(tài)系統(tǒng)和經(jīng)濟(jì)系統(tǒng)的紐帶,從生態(tài)經(jīng)濟(jì)的角度,給出了水資源承載力的概念.在總結(jié)水資源承載力的特點和研究方法的基礎(chǔ)上,將水資源承載力的研究納入了生態(tài)經(jīng)濟(jì)系統(tǒng)的背景下進(jìn)行綜合集成研究.以黑河流域中游為例,提出了研究水資源承載力的多目標(biāo)模型和納入生態(tài)價值模塊的途徑和方法,從價值量的角度對流域生態(tài)系統(tǒng)和經(jīng)濟(jì)系統(tǒng)進(jìn)行了初步的耦合研究,并根據(jù)模型的優(yōu)化分析結(jié)果分析了未來20a黑河流域張掖地區(qū)的水資源承載力。

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.
