[Objective] Landscape forest is synthetically evaluated in order to provide scientific basis for alteration and construction in northern mountain of Meilie district, Sanming city. [Method] According to the indexes of landscape effect, ecological efficiency and healthcare function, the comprehensive evaluation for landscape forest on both scenic beauty and ecological quality is put forward based on questionnaires and sample-plot survey, combined with analytical hierarchy process （AHP）. [Result] The scores for scenic beauty in Area A,B and C are respectively 13.35,10.30 and 10. 80,ecological quality 0.67,0.33 and 0.38. Accordingly they are all low in the two aspects,and the order is Area A〉 Area C〉 Area B. [Conclusion] The total quality of landscape forest is poor in northern mountain, revealing that the landscape forest should be reconstructed urgently, due to the single forest phase, the few broadleaf and color-leaved species,the lack of ground covers under trees,the confusion of tree stratum structure and the poor community stability,etc.
