Taking Ugan-Kuqa River Delta Oasis as the research site, basing on the theory of ecological security assessment, the system with 32 ecological safety evaluation indexes from natural ecosystems, ecomomic systems and social ecosystems was established, and by using the principal component analysis quantitative method in evaluating the trend of oasis ecological security in 17 years (from 1995 to 2011), economic development level factors, agricultural development potential factor, social development potential factor and water resources factor had been extracted. Results of the study have shown that the oasis developed from insecurity to security between 1995 and 2011. From 1995 to 2001, the system was in unsafety level, from 2002 to 2003, the system was criticality safe, from 2004 to 2007, the system was relatively safe, after 2008, the system was safety. The BP neural network was used to predict the oasis in the years from 2012 to 2016, the integrated evaluation of ecological security was 1.477 1, 1.519 3, 1.604 4, 1.657 3, 1.692 9, respectively. Ecological security evaluation and prediction can be used to ensure that oasis ecological security, coordinate regional economic development and ecological environment.
