      摘要: 歐洲中部的易北河流域是典型的濕潤半濕潤地區(qū)。夏季的水資源供給是限制農(nóng)業(yè)生產(chǎn)的因素之一,特別是在具有較高農(nóng)業(yè)生產(chǎn)力水平,而年降水量只有500 mm的黃土地區(qū)。通過總結(jié)氣候變化與水文循環(huán)(GLOWA-Elbe)項目第一階段的成果,根據(jù)氣候和土地利用變化的各種情景并考慮其不確定性,對未來50 a德國易北河流域水資源供給穩(wěn)定性作出綜合評估。研究表明,歐洲中部必須從自然和社會角度應(yīng)對未來氣候變化情景下產(chǎn)生水資源供給短缺的可能情況。

      Abstract: The Elbe region is representative of humid to semi-humid landscapes in Central Europe, where water availability during the summer season is the limiting factor for plant growth and crop yields, especially in the loess areas with high crop productivity having annual precipitation lower than 500 mm. This paper summarizes the results of the first phase of the GLOWA-Elbe project and tries to assess the reliability of water supply in the German part of the Elbe River basin for the next 50 years, a time scale relevant for the implementation of water and land use management plans. One focus of the study was developing scenarios which are consistent with climate and land use changes considering possible uncertainties. The concluding result of the study is that nature and communities in parts of Central Europe will have to deal with considerably lower water resources under scenario conditions.
