Abstract: In this study, we constructed the habitat evaluation models of larch plantation grown at the Mengjiagang Forest Farm of Jiamusi City, Heilongjiang Province of northeastern China by using fuzzy analytic hierarchy process ( FAHP), and calculated the weights of various indicators based on the identified hierarchical structures of the models. First, criterion layer was used to determine the evaluation indicators related to site conditions and habitat management factors, and the corresponding weights were 70% and 30%, respectively. Second, the weights of secondary evaluation indexes in the constructed models were slope(I1) 0.1901, aspect(I2) 0.1633, slope position(I3) 0.170 1, agrotype (I4) 0.163 3, soil thickness(I5) 0.180 1, canopy density(I6 ) 0.133 3, infrastructure(I7 ) 0.399 7, construction of laws and regulations(I8) 0.316 9, and the level of scientific research(I9 ) 0.283 3. In this study, the constructed plantation habitat evaluation system, based on plantation habitat evaluation models, achieved good integration of habitat evaluation results and GIS technique. It is useful for researchers to apply the criterion tree planting matching the site. Meanwhile, it provides references for forest development.
