According to the characteristics of complexity and importance of research on ecological security of river basin, this article chose heavy polluted tributary Zhaosutai River basin of Liaohe in Jilin Province as the study area. Based on catastrophe progression method, and combining with the Pressure-State-Response framework, the ecological security catastrophe progression model of Zhaosutai River basin was built, analysis on the ecological security situation of 8 townships in the river basin in the year of 2004, 2008 and 2010 was carried out. Results show that the ecological security of the study area in 2010 decreased compared with the year of 2008. Among them, ecological security of 3 townships is at a better level; 3 townships are at the early warning of ecological security level; the other is at the moderate level of alert. Attention should be paid to the decline of ecological security of basin.The relevant departments should take effective measures to improve the level of ecological security of Zhaosutai River basin in order to realize the sustainable development of the basin of the society, economy, environment such as increase of environmental protection investment, building township sewage treatment plant and so on.
