京津冀地区水资源承载力评价

以“水资源-经济社会-生态”为基本框架,构建了京津冀地区水资源承载力指标体系,并基于组合赋权法和分层模糊综合法评价了2000-2014年13个行政区水资源承载力状况.结果表明:京津冀地区水资源承载力偏低,其中北京、天津、邢台、邯郸等地承载力较弱,应加快经济重心转移和产业结构调整;张家口、承德、秦皇岛市水资源承载力较强,应保持可持续发展,实现其生态屏障功能. 

Evaluating water resources-carrying capacity in Beijing-Tianjin-Hebei region

Due to population explosion and extensive natural resources exploitation,China is facing an extreme water crisis,especially in the Beijing-Tianjin-Hebei region.Evaluating water resources-carrying capacity for Beijing-Tianjin-Hebei region is very important to ensure the sustainability of regional environment health and economy.A water resources-carrying capacity index framework was built based on the "watereconomy-ecology" system,an improved fuzzy comprehensive evaluation method was used to evaluate the carrying capacity of water resources in Beijing-Tianjin-Hebei region (13 districts),for 2010-2014.The carrying capacity of water resources for Jing-Jin-Ji region was found to be un-desirable.The water shortage problem was found to be severe particularly in Beijing,Tianjin,Xingtai,and Handan.On the other hand,the carrying capacity of water resources in Zhangjiakou,Chengde,and Zhangjiakou were found to be very high,and these areas should maintain sustainable development to complete their ecological protection mission.
