摘要
本文以四川盆地低山丘陵区68个县森林资源现状为基础，探讨了森林承载力的概念，评价森林承载力的指标及提高森林承载力的途径。指出：森林承载力由森林生态系统物质产品的供应强度和非物质产品效能供应容量即环境负荷能力两个主要部分构成。通过合理调整农林结构，林种比例及树种配置，改善森林的内涵质等措施，显著地提高了森林承载力，使森林人口承载力和环境负荷能力由目前的超载转变为富余状况。
Based on the forest resources of 68 counties in the Sichuan Basin,the forest carring capacity (FCC) is defined, and the estmation standards of FCCand the way of imyroving FCC are studied. The results indicate that if the forestguality, the structure of forest category and tree syecies are improved, the FCCwill be optimized. The FCC for regions of middlelow mountains, low mountains,deep hills. Shallow hills and plains are given respectively.
