Analysis of forest landscape edge effect intensity based on analytic hierarchy process

From two aspects of productivity and species diversity,t he the edge effect intensity of forest landscape plaques and edge area were comparatively analyzed,and the total edge effect intensity was calculated according to AHP general ranking.The results show that a majority of the forest landscape patches in different community structure had a positive effect,from the age group analysis the strength of mature forest edge effects was more than that of middle-aged forest's,and the young forest's edge effect was not obvious;analyzing from forest landscape type,the ranking of the forest landscape patch edge effect was as follows:China fir and pine forest pine and broadleaf forest ,pine and broadleaf forest China fir and broadleaf forest;China fir and pine belong to coniferous forest,they are similar to each other to a large extent,this confirms the same-sex repulsion.
