采用层次分析法和耦合理论分析森林景观类型间耦合程度,以西洞庭湖区为例,计算不同景观类型不同龄组的耦合度,结果表明:景观类型之间相似程度越大,耦合度越小,从龄组来看,幼龄林耦合度最小,中龄林耦合度最大,成熟林达到稳定状态,说明耦合是一个动态过程. Using the analytic hierarchy process and the coupling theory to analyze the coupling degree of forest landscape types. Taking the Dongting Lake area in the west as an example, the coupling degree of different landscape types in different age groups was calculated. The results showed that the greater the degree of similarity and the smaller the coupling degree, In terms of age group, young couple had the least coupling degree, middle-aged couple had the highest degree of coupling, and mature branch had reached a steady state, indicating that coupling was a dynamic process.
