摘要
摘要 根据水资源承载能力内涵，提出水资源承载能力定义，构造了水资源承载能力双指针计算模型，提出了超载度及宽松度概念。对山西省大同市的水资源现状承载状态分析表明，大同市已处于轻度超载状态，超载度为1.08～1.15；在未来水平年，若大同市在本地（永定河流域区）水资源基础上仍采用常规发展模式，水资源超载程度将加剧。最后讨论了提高大同市水资源承载能力的途径。
According to the connotation of the water resources carrying capacity （WRCC）, the paper gives the definition of the water resources carrying capacity and constructs the dual indices calculation model of the water resources carrying capacity, proposes the concept of the surcharge degree and the flexible degree of WRCC. Analyzing the WRCC of Datong shows that its water resources carrying condition is mildly beyond its carrying capacity, and the surcharge degree is 1.08-1.15. The city＇s future WRCC indicates that if Datong still uses conventional development pattern on the local water resources, its water resources carrying condition will be worse. Finally, the paper discuss how to improve the city＇s WRCC.
