| 摘 要： | 水资源的用水结构和承载力的计算是当前人们普遍关注的问题,探讨县域水资源承载力是维持县域经济社会健康发展的重要环节.从长武县2007年水资源现状出发对县域范围内的用水结构及水资源承载力平衡指数进行计算与分析.结果表明:长武县用水结构中,农业、工业、生活、养殖业用水量比例分别为0.65:0.29:0.04 :0.01,农业用水占总用水量的1/2以上;长武县可利用水资源量大于总用水量,水资源承载力供需平衡指数大于0,说明长武县水资源供给充足,具备当前规模的经济社会系统的支撑能力. |

| Abstract: | The issues about water resource usage structure and carrying capacity are being paid more attentions nowadays due to the water resources carrying capacity (WRCC) plays an important role in county's economic and social sustainable development. In this paper, the water resources of Changwu County in the year of 2007 is taken as the example, the water resources usage structure and carrying capacity balance index are calculated separately. The results show that the water resources usage structure of Changwu County mainly include 4 parts: agriculture, industry, life and farming, and their consumption rates are 0.65:0.29 : 0.04 : 0.01, while the agricultural usage accounts for more than half of the total water consumption. According to the calculation of the WRCC balance index, the available water resources volumes is greater than the total water usage volumes, and the WRCC balance index is greater than 0, which notes that the water supply of Changwu County is adequate, and the water resources can meet current usage demand of current economic and social systems. |
