摘　　要：以厦漳泉地区17个典型乡村为研究对象,采用尖点突变模型测算出其生态安全突变值,根据其突变值对乡村生态安全状态进行识别,并进行归类、分析。研究结果表明,研究对象生态安全状态可分为上叶稳定状态、下叶稳定状态、中叶状态3种类型;一直处于上叶状态的乡村有5个,处于下叶状态的乡村有4个,处于中叶状态的乡村有8个。在此基础上,对其原因进行分析,并提出管控措施。Taking 17 typical villages in Xia-Zhang-Quan area as the research object,the cusp mutation model is used to calculate their abrupt values of ecological security,and the state of rural ecological security according to their abrupt values is identified.The results are as follows.The ecological security state of the research object can be divided into three types:upper leaf stable state,lower leaf stable state and middle leaf stable state.Five villages are in the upper leaf state,four are in the lower leaf state,and eight are in the middle leaf state.Finally,the measures of zoning control are put forward to improve ecological security.
