| 摘 要： | 流域水空间是与径流密切相关、直接受洪水波及的地表以及此范围内地下含水层系统所共同占据的空间。恢复和保护土地水文功能,实现流域水和土的联合管理已成为流域管理的重要内容。在水空间研究的基础上,结合流域特征,提出流域水空间概念,对流域水空间内涵、分类、边界、度量、结构和特征进行探讨,并建立流域水空间研究框架,包括流域水空间功能识别、流域水空间特征分析、流域水空间安全预警、流域水空间规划以及流域水空间维护和管理等内容。

| Abstract: | The catchment space for water,used as an expedient to apply water space theory at catchment scale,is one kind of space that encompasses river and its branches,linked lakes,wetlands and other kinds of water bodies,floodplains and partial slops that directly affected by flood,as well as the corresponding aquifer systems within these areas.Modification of catchment areas by human activity has led to dramatic changes in the flow of water.The overuse of land has destroyed lateral and vertical pathways taken by water draining to a stream,and disturbed runoff process and redistribution of rainfall,which has lowered water readjustment ability of lands within the catchment areas.As a result of human impact,hydrological function of water storage,water detention and groundwater recharge through lands within catchment area have been decreased,but meanwhile flood and drought disasters have been increased.These problems have been paid much more attention by hydrologists and ecologists recently.How to restore and protect hydrological functions of lands along river has become one of important aims in catchment management.Space for water,provided as one of solutions to achieve sustainable water resource use,puts emphasis on these spaces like wetlands,forests,lakes and floodplains and their important hydrological role of water cycle and their influence on sustainable utility of water resource.Through these analyses,the concept of the catchment space for water is provided,based on the concept of space for water,and the connotation,classification,boundary,measurement,structure and characteristics of catchment space for water are discussed.Framework of the study is then proposed,aiming at setting up theory frame of catchment space for water and providing theoretical instruction and technical support for integrated water and land management at catchment scale. |
