社会经济情景的设定是全球气候变化研究的基础,也是气候变化影响评估的关键环节.本文回顾了社会经济情景的发展过程,阐述了共享社会经济路径的主要特点和最新发展趋势,介绍了区域社会经济情景的构建及在灾害风险领域中的应用,最后对共享社会经济路径的发展进行了展望.  相似文献

The effects of Gracilaria verrucosa (Huds.) Papenf. remediated eutrophication in fish cage-farming areas were studied.at Xiangshan Harbor, Zhejiang Province in May 2007. The resuIts demonstrated that the effects of bioremediation of eutrophication of mariculture waters by G. verrucosa were obvious. The specific growth rate of G. verrucosa with single cultivation was higher than co-culture of G. verrucosa and fish, it could reach to as high sa 9.9% in 12 days. NH4-N removing efficiency of G. verrucosa could reach to as high as 86% in 10 days. DO in bioremediation area was significantly higher than that in non-bioremediation area (p<0.05), COD, NH4-N, NO3-N, NO2-N, PO4-P in bioremediation area were significantly lower than that in non-bioremediation area (p<0.05). The N, P concentration exceeded the 4th class of seawater specified before bioremediation, after 10 days the N, P concentration were greater than the 4th class of seawater specified by cultivation of G. verrucosa. The effect of G. verrucosa remediated eutrophication with co-cultivation was better than single cultivation of G. verrucosa. Large-scale cultivation of G. verrucosa could be a good solution to the problem of eutrophication due to their capability of removing nutrients.  相似文献
