Based on pressure-state-response (PSR) model which was used to assess the landscape ecological risk and projection pursuit method, a landscape ecological risk assessment model was established for Jingzhou City, Hubei Province. The results showed that, Jingzhou City suffered increasing risk from 1995 to 2013 with landscape ecological risk index (LERI) from level I to level IV. Pressure index (PI) increased continuously, state index (SI) decreased, while response index (RI) increased gradually with the influence of economy and policy. The assessment results also showed that with the increasing pressure of society, the quality of landscape ecosystem decreased increasingly, but strengthening environmental protection measures could relieve the risk obviously, and made the risk to increase slowly.
