摘 要:森林作为生态系统的重要组成部分,在提高环境质量方面发挥着重要的作用。本文根据南充1999-2013年森林发展及森林二类资源调查相关数据,运用层次分析法、综合指数法等方法,对南充市森林承载力指数进行计算,得到其目标层森林承载力指数(FCC)为1.0079,其中三个准则层承载指数分别是经济承载指数(FCC1)为0.9508;生态承载指数(FCC2)为1.1171;社会承载指数(FCC3)为0.3351。通过森林资源可持续评价划分标准对南充市森林状态进行评价显示,南充市森林资源承载力已处于超负荷状态,今后要注重林种结构的优化、病虫害防治等方面的工作。Forest is an important part of ecological system, and it plays an important role in improving environmental quality. Based on investigation data of Nanchong forest development and forest resources II from 1999 fo 2013, forest carrying capacity index of Nanchong city was calculated, in which AHP and the comprehensive index method were used. Results showed the forest carrying capacity index (FCC) of target layer was 1.0079. Carrying indexes of three criteria layers were 0.9508, 1.1171, 0.3351, respectively, including economic carrying index ( FCC1 ), ecological carrying index (FCC2), and social carrying index (FCC3). Forest state evaluation of Nanchong was carried out though evaluation criteria of sustainability of forest resources. Results showed forest resources carrying capacity of Nanchong city was in the overload condition, and more attention should be paid to optimization of forest category structure, pest control and other aspects of the work.
