摘　　要：首先综合考虑森林资源物质及非物质特性,利用11个细化指标,构建了衡量区域森林资源丰裕状况的单一量化指数,解决了以往森林资源衡量不全面的问题。然后利用中国第六、第八次森林资源普查数据,对各省区及不同林区森林资源丰裕度的相对变化进行分析。结果显示:两次森林资源普查期间,中国森林资源丰裕度由3.996增加至9.285,年均增长约8.8%,整体进步明显;森林资源分布呈现显著的区域不均衡特征,广东省的森林资源丰裕程度最高,约为14.823,而山西省最低,仅为3.701,约为广东省森林资源丰裕程度的24.96%;不同林区森林资源增长速度及丰裕度现状均存在差异,南方林区森林资源增长率最高为10.6%,东北林区森林资源增长率最低为5.1%,西南林区的森林资源丰裕程度最高,约为12.308,其他林区森林资源丰裕程度最低,约为7.126;森林资源丰裕度的变化与初始森林资源状况呈负向关系,区域间森林资源变化存在一定的趋同性。⑴Background——Forest resource abundance is a comprehensive index to characterize quantity and quality of forest resources and non-material resources.The previous researches measured the abundance of forest resources only by using the characteristics of the physical resources including the quality and quantity about woodland resources and forest resources.However,measure the abundance of forest resources is needed to research the overall effect of forest resources.Therefore,it is an urgent problem to combine and quantify the material resources with biological characteristics and non-material resources with social and economic characteristics in forest resources. ⑵Methods——This paper constructed forest resources abundance index system which contained 11 detailed indexes.Furthermore,the data were from Sixth National Forest Resources Inventory,Eighth National Forest Resources Inventory and China Statistical Yearbook(1999-2013).In the absence of data in some provinces,a total of 22 provinces(include Shanxi,Inner Mongolia,Liaoning,etc.)were selected as the sample areas. ⑶Results——The data from the National Forest Resources Inventories show that all the provincial forest resource abundance index had increased,China's forest resource abundance increased from 3.996 to 9.285,the average annual growth is about 8.8%,and the overall progress is obvious.The distribution of forest resources shows a significant regional imbalance.The forest resources abundance in Guangdong province is highest,and the forest resources abundance in Shanxi province is lowest,which indicate that there is a large gap about forest resources abundance in different provinces and the spatial distribution of forest resources is not balanced.In different forest areas,the size and growth rate of forest resources abundance is different.The size of forest resources abundance in forest area southwest China is highest,and the forest resources abundance index is about12.308.The growth rate of forest resources abundance in forest area southern
