Calculation of Emergy Transformity of Water Resource in Taihu Lake Watershed
摘要
Abstract
Water resource is regarded as a complex system and is quantitatively analyzed by using the theory and method of emergy.The water system in Taihu Lake watershed is taken as a research object.Emergy system dia-grams and emergy analytical tables were obtained and the emergy transformity of water supply resource of the water-shed from 2007 to 2011 was calculated.Result shows that the emergy transformity of the watershed’s water re-source has a tendency of increasing over years,which is consistent with the practice of intensifying regulation pro-jects to improve water environment.Besides,the emergy transformity of water resource under human disturbance increased by 24.3% on the average compared with the natural condition,and the increment displays a trend of in-creasing year by year as well,from 4.31% in 2007 to 36.4% in 2011,indicating that safe water supply takes more cost despite the rich water resource of the watershed,and that water shortage of water-quality type is a new chal-lenge of the century.关键词
