摘要
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.
With West Dongting Lake region as an example,the paper analyzes the coupling degree of different forest landscape types based on AHP（analytic hierarchy process） and the coupling theory,calculates the coupling degree of different landscape types or different age groups.The results show that the greater the similarity between the landscape types,the smaller their coupling degree.Young forests have the least coupling degree,half-mature forests have the largest coupling degree,and the mature forests show a stable state,suggesting that coupling is a dynamic process.
