- It's urgently needed to solve the "Engineering water shortage" problem cause of serious leakage of surface water, poor water resources availability and difficult water resources utilization in Karst area in Southwest China. To reasonable evaluate water resources security situation in karst area, this paper based on the conceptual model of Water demand pressure - Engineering water shortage - Carrying state - Ecological basis - Human response (PESBR) to build evaluation index system of water resources safety which covered condition of water conservancy engineering, then adopted the coupling model of Set pair analysis and Markov chain (SPA-MC) to dynamic evaluated water resources security situation in Guiyang city during 2002~2014. Research results shown that: the water resources security of Guiyang City in 2008, 2012, 2014 are belongs to "safe" level, the rest years are "general safe" level. And it is transiting from "general safe" to "safe" on the whole. The average safe grade contact f2 and f3 are 0.13 and 0.20, confidence level H2 and H3 are between 0.5 degrees. The prediction result of water resources security in Guiyang city during 2015 to 2050 shown that the future water resources security will remain "general safe" level for long time.
