对气候变化背景下中欧易北河流域可用水的评估
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(GLObal WAter)-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.
