摘要
随着当今科学技术日新月异的发展 ,不同学科的界限逐渐模糊 ,重叠交叉越来越明显 ,精确化与数量化方法与手段逐步完善 ,新的学科生长点不断出现。生态环境用水研究是当前生态学、水文学、土壤学、环境科学等的前沿领域与热点之一 ,尤其是联系生态过程与水文过程 ,描述生态演化与水资源相互关系的关键指标与中心问题。 2 1世纪全球问题 (人口 -资源 -环境-发展 )变得更加严峻 ,生态环境用水研究面临着如何满足社会的经济可持续发展对水资源日益增长需要的挑战。近 6年来有关生态用水研究在概念、重要性、理论计算方法、不同生态系统背景下水资源承载力等方面都有了共识并取得了有意义的发展 ,本文旨在有关工作基础上 ,对上述相关方面及存在的问题进行论述 ,为推动国家进行大规模的生态环境建设在理论和实践方面提供参考。
With the rapid development of sci-technology,the boundary among different disciplines is gradually unclear ,the overlapping and intersecting are more and more obvious,the means and methods of precision and quantitation become perfact with a continual occurrence of new-discipline .The study of ecoenvironmental use of water is one of the frontiers and popular problems of current ecology,hydrological science,pedology,environmental science and so on, especially the bridge connecting ecological course and hydrological course,the key index and the central question for descriping the interconnection of ecological succession and water resources.Because of the urgency of the global problems (Population-Resource-Environment-Development,PRED) ,This study will be confronted by the challenge in the 21 st century,which is how to meet the need that social and economic sustainable development deponds upon gradual increasing for water resources. In the past four years in this field, probes about the concepts ,significance,theorical computational methodology,water-resource.carrying capacity under different ecosystem backgrounds has seen many meaning progresses and shared a common genalization.The aim of the paper is that on the basis of related work of our state key laboratory, we reviewed these aspects and pointed out the existing problems and outlooked the future of the field for the reference of environmental construction on a large scale in China.
