摘要：
Study on land ecological safety can help people acquire the states and changes of land ecosystem. It is of great significance to realize the reasonable utilization of land resource. The paper constructed an evaluation index system of land ecological safety based on Pressure-State-Response model. Then the paper combined fuzzy mathematics and matterelement theory to establish an evaluation model of land ecological safety. Finally the paper developed a case study on the nine cities along the Changjiang River in Anhui Province. The sequence of land ecological safety of the nine cities is: Xuancheng > Hefei > Maanshan > Tongling > Wuhu > Chuzhou > Chi zhou > Chaohu > Anqing. Conditions of the nine cities all belong to critically safe grade. In addition, the paper analyzes ecological safety conditions of the three elements, the evaluation indexes of the nine cities. The model evaluates the conditions of land ecosystem more comprehensively and accurately and provides a new way to evaluate ecological safety.
