In this study, the important city of Guanzhong Plain-Weinan, was studied and its ecological security index changed from the year of 2000 to 2012. The stress-state-response (PSR) model was used to establish an ecological security assessment system based on agricultural development cities. The method of quantitative research including 12 indicators based on the fuzzy analytic hierarchy process (FAHP) model was constructed, and the main aspects such as the natural environment, economic society, and human activities were designed. The results showed that from 2000 to 2012, the area of ecological security and stability is gradually increasing, and the stability of the ecological environment is enhanced. The ecological security level in the central region of the country has developed well in the past 10 years, but the ecological security level in some areas has gradually increased in edge area.
