摘要
探讨了干扰、干扰状况、缀块及缀块动态等相关概念，并在已有的研究和认识基础上，给出了干扰的一般性定义，即干扰是阻断原有生物系统生态过程的非连续性事件，它改变或破坏生态系统、群落或种群的组成和结构，改变生物系统的资源基础和环境状况．
The disturbance theory of ecology and its study advance were briefly introduced and the concepts of dusturbance,disturbance regime,patch,patch dynamics were discussed.Based on the researches and knowledge we have obtained,we suggest a general definition of disturbance as follows:disturbance is the events that break the ecological process of the original biological system,it changes or destroys the composition and structure of the ecosystem,community or population,and changes the resource basis and environmental state of the biological system.
