森林资源二类调查是获取各基层单位森林资源现状与分布的主要方法,根据江苏省2009年森林资源二类调查结果,笔者通过提取各类林地、林木、林种、乔木林、竹林和灌木林的组成及分布等森林资源主要数据,并对单位面积蓄积、单位面积株数和树种结构等因子进行了对比分析,客观地反映了江苏森林资源快速增加、幼中龄林占优势地位、非公有制林业快速发展、林种结构渐趋合理及杨树后备资源丰富等资源特点。
The provincial forest management inventory is a major meansure to gain situation and distribution about forest re- sources of basic unit. According to the data of the provincial forest management inventory of Jiangsu Province in 2009, the author compared the data about composition and distribution of species in various forests, bamboo forests and shrub forests, and analyzed factors such as stock volume per unit area, indivicuals of trees per unit area and tree structures and proved that the Jiangsu forest resources increased rapidly, the immature forests was in domain, the non - public forests developed fast, the species structure grew reasonable, resources of reserved poplar tree resources were plentiful and so on .
