      摘要: 運用中國科學(xué)院農業(yè)政策研究中心開(kāi)發(fā)的中國水資源模型,模擬分析了氣候變化條件下海河流域的水資源短缺狀況及相應的適應性措施的有效性。結果表明:隨著(zhù)社會(huì )經(jīng)濟的發(fā)展,到2030年海河流域的水資源短缺比例將提高25%,氣候變化將使水資源短缺比例進(jìn)一步提高2%~4%。無(wú)論是供給管理還是需求管理的適應性措施,在緩解水資源短缺方面都具有一定的有效性。但是,多標準的評估結果表明,所分析的幾種需求管理的適應性措施比供給管理的適應性措施的可行性更高。在需求管理中,采用既提高灌溉水價(jià)又提高工業(yè)水價(jià)的混合水價(jià)政策可能是最優(yōu)的策略選擇,采用農業(yè)節水技術(shù)為次優(yōu)策略選擇。

      Abstract: Water shortage under climate change in the Haihe River basin and the effectiveness of adaptation measures were simulated and analyzed using China's Water Simulation Model. It shows that, with socio-economic development, water shortage in the Haihe River basin will increase by 25% in 2030, and climate change will further increase the shortage in water resources by 2%-4%. Both supply management measures and demand management measures can play important roles in mitigating water shortage. However, based on the multi-criteria assessment results, it is more feasible to implement demand management measures than supply management measures. For demand managements, the best policy is the mix water price policy through increasing both irrigation and industry water prices, and the next is adopting agricultural water-saving technology.

      Key words: climate change, water shortage, adaptation measures, Haihe River basin
