摘　　要：在森林资源可持续发展理论指导下,构建了森林资源可持续发展力综合评价指标的体系。以白龙江林区为例,通过对所选择的5个策略层(中间层,B层),20个措施层(最低层,C层)指标值的计算和纠正,建立森林资源可持续发展力评价的协调度模型:DH=∑B_iP_i,1996年的DH=0.5320,2000年的DH=0.6100,虽然均小于其理论值0.7000,判定该林区处于非可持续发展状态,但同时表明该林区正向可持续发展目标前进。Based on the theories of sustainable development of forest resources, this paper constructed an index system for the integrative evaluation on the sustainability of forest resources in Bailon River forest region of Gansu Province. After calculated the index values of five strategic levels and twenty measure levels, the degree of harmony (DH) was obtained, with which, the sustainability of test forest resources could be evaluated. The DH value was 0. 5320 in 1996 and 0. 6100 in 2000, which was smaller than the theoretic value of 0. 7000, and hence, this forest region belonged to non-sustainable development, but made some progress for its sustainability.
