基于荷载均衡的喀斯特地区地表水资源可利用量研究——以六冲河流域为例

Study on available surface water resources in karst area based on load and resistance balance:Take Liuchong river basin as an example

以贵州省毕节市六冲河流域为主要研究对象,在分析该地区水资源承载状况的基础上,选用生态足迹法计算六冲河流域水资源承载力,采用扣损法计算流域水资源可利用量并考虑洪家渡电站运行对六冲河流域水资源可利用量的影响。结果表明,六冲河流域水资源承载状况良好,水资源可利用量为24.51亿m^(3),能为区域社会经济的发展提供较好的水资源条件。

Taking Liuchong river basin in Bijie city of Guizhou province,China as the main research object,on the basis of the analysis of the regional water resources carrying condition,using the ecological footprint approach,the water resources carrying capacity of the Liuchong river basin is calculated.Use buckle loss method,the river basin water resources availability is calculated,and the impact of the operation of Hongjiadu hydropower station on the available water resources of Liuchong river basin is considered.The results show that the water resources carrying capacity in Liuchong river basin is good,and the available water resources is 2.451 billion cubic meters,which can provide better water resources conditions for the development of regional social economy.
