摘要:
 运用Matlab平台BP神经网络将全国第五次至第七次森林清查数据进行了分析，对我国各省区森林资源在近15年间的发展变化作出评价，结果显示，在第五次至第六次森林资源清查期间，我国森林资源主要储备区域出现较大幅度的资源退化。结合木质林产品的国际贸易的研究及数据分析，认为我国森林资源利用存在省域间的资源剥夺状况，这种状况形成的制度路径，可能带来森林资源的低效利用和保护措施难以实施的问题，导致森林资源生态价值的持续损失。第七次森林资源清查期间，由于天保工程和人工林面积增长构成了森林覆盖率增长的主流。
Abstract:
 In this paper,BP neural network of Matlab platform was used to analyze the fifth, sixth and seventh national forest inventory data,to evaluate the development and changes of forest resources in the provinces and autonomous regions in China in recent 15 years.The results showed that there was a substantial degradation of forest resources in the major reserve reagions during the fifth to sixth forest inventory.Combined with the research and data analysis of the international trade of forest wood products,it was considered that there existed the situations of inter-province-domained forest resource deprivation,which would lead to the problems of inefficient use of forest resources and difficulty to implement protection measures, and also would lead to the continued losses of ecological value of forest resources.
