摘要

[目的] 对甘肃省水安全状况进行评价，为该区相关部门制定相应的区域水安全措施提供科学依据。[方法] 通过构建DPSIR评价指标体系，运用熵值法和单指标量化—多指标综合—多准则综合的方法对甘肃省2000，2005，2010，2015和2018年水安全进行评价。[结果] 甘肃省水安全健康指标由2000年的不安全上升至2018年的较不安全，总体呈上升趋势，但幅度较小，处于基本安全线以下。对于准则层而言，驱动力上升缓慢，压力依然较大，而响应水平有限，是甘肃省水安全健康指标向更好状态发展的主要限制因素。该省水安全状态和影响虽处于较不安全状态，但逐年稳步上升，是推动甘肃省水安全健康指标向更高水平发展的重要动力。[结论] 甘肃省水安全现状不容乐观，处于不安全状态。需要从水资源、生态环境和社会经济3方面入手改变水安全现状。

Abstract

[Purpose] The water safety in Gansu Province was evaluated

in order to provide scientific basis for local departments to formulate corresponding regional water safety measures.[Methods] By constructing DPSIR evaluation index system

water safety of Gansu Province in 2000

2005

2010

2015 and 2018 was evaluated by using the method of entropy value and single index quantification

multi-index synthesis and multi-criteria synthesis.[Results] The water safety and health of Gansu Province had increased from unsafe in 2000 to less unsafe in 2018

showing an upward trend on the whole but to a lesser extent

it was still below the basic safety line. As for the criterion level

the driving force rose slowly and the pressure was still high

while the response level was limited

which was the main limiting factor for the development of water safety and health to a better state. Although the state and influence were in a less safe state

they increased steadily year by year

which was an important driving force for the development of water safety and health to a higher level.[Conclusion] The current situation of water safety in Gansu Province is not optimistic and unsafe. It is necessary to change the current situation of water safety from three aspects:water resources

ecological environment and social economy.
