| 摘 要： | 在灾害链定义的基础上提出了灾害地貌链的定义 (即由地貌灾害所构成的灾害链 ) ,基于不同的标准将其划分为不同的种类 ,运用苏姆的地貌临界理论对地貌灾害中的两种临界进行浅析 ,最后运用耗散结构理论来探讨灾害地貌链中的临界过程。

| Abstract: | In view of the definition of disaster chain, this paper postulates the definition of disaster geomorphologic chain, a disaster chain made of series of geomorphologic disasters The disaster geomorphologic chain can be divided into different types on the basis of the different criteria Two kinds of thresholds in geomorphic disasters are analyzed according to Schumm's geomorphic theory Finally, the critical process in the disaster geomorphologic chain is discussed by using the theory of dissipation theory |

| Keywords: | disaster geomorphologic chain theory of dissipation structure critical process |
