| 针对喀斯特地区水资源系统存在的问题，运用熵权因子分析方法分析了喀斯特地区水资源系统的主要影响因子，并通过综合得分结果对喀斯特地区水资源系统进行诊断分析。结果表明：喀斯特地区的主要影响因子有人类活动影响因子、水量因子和水资源脆弱性因子；从年际变化来看，喀斯特地区水资源系统整体状态在波动中表现出良好的发展趋势，其中2001、2003和2006年水资源系统状态较低，2014和2015年得分较高，水资源系统状态明显好转；可见，人类活动下的经济发展模式和环境生态的保护、基础水利设施的完善是保证喀斯特地区水资源安全利用的前提，而且能够有利于积极应对异常气候变化下对水资源量的影响。 |

| Abstract: |
| In view of the problems existing in the water resources system in the Karst region,the entropy weight factor analysis method is used to analyze the main influencing factors of the water resources system in the Karst region,and the diagnosis and analysis of the water resources system in the Karst region are carried out through the comprehensive score results. The results show that the main influencing factors in Karst area are human activities,water quantity and water resources vulnerability. From the perspective of inter-annual changes,the whole state of water resources system in Karst region expresses good development trend in the fluchuation as a whole, among which the water resources system state in 2001,2003 and 2006 was relatively low,and the water resources system state in 2014 and 2015 was relatively high,and the water resources system state was obviously improved. It can be seen that the economic development mode under human activities,the protection of environment and ecology,and the improvement of basic water conservancy facilities are the premise to ensure the safe utilization of water resources in Karst areas,and can be conducive to actively coping with the impact of abnormal climate change on the amount of water resources. |
