Research on the connotation and assessment of water security<br /> —— Take Wanzhou district of Three-gorge Reservoir as an illustration<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 7
Abstract
In this paper, connotation of water security is discussed and three dimention concept model is put forward on the basis of content, goal and time. On the precondition of determinate goal and time, water resource security, water environmental security and water ecology security are the main part of water security assessment, and this three elements of water security are also the core factors to determine the level of water security. Based on the connotation of water security, the assessment indicator system of water security, the assessment methed and standard are put forward. Further more, the present water security is assessmented, and future water security is assessmented by using scene analysis method. Integrated present assessment result showed that the water security is general, and future assessment result showed that the water security of general development scene is decline while the optimize development scene’s is well. In the future, restoring the loss of soil and water, controlling the pollution discharge and raising socioeconomic water use efficiency are the main approaches to improve water security level of Wanzhou district.
