陕西省延安市桥山林业局2005年二类调查森林资源统计数据桥山林业局各林场森林、林木面积蓄积结构情况表

本数据记录了陕西省延安市桥山林业局森林资源统计数据中桥山林业局各林场森林、林木面积蓄积结构情况表的统计单位、活立木蓄积量、有林地面积合计、乔木林面积小计、乔木林蓄积小计、针叶林面积、针叶林蓄积、阔叶林面积、阔叶林蓄积、混交林面积、混交林蓄积、疏林地面积、疏林地蓄积、散生木株数、散生木蓄积等记录。森林资源统计数据在林业科学研究和森林资源管理中十分重要的数据，包括不同森林类型的空间分布状况、面积大小，行政区划及区划代码等信息。森林资源统计数据包括国家级、省级、县级及林场等级别。目前的森林资源统计数据很多是由二类调查资料或一类清查数据获得的，是在林业生产中十分重要的统计资料。

This dataset includes the statistical entries such as statistical units, growing stock volume of live trees, total area of closed-canopy forest land, subtotal area of arbor forests, subtotal growing stock volume of arbor forests, area of coniferous forests, growing stock volume of coniferous forests, area of broadleaved forests, growing stock volume of broadleaved forests, area of mixed forests, growing stock volume of mixed forests, area of sparsely wooded land, growing stock volume of sparsely wooded land, number of scattered trees, and growing stock volume of scattered trees, sourced from the forest area and stock structure statistics table for each forest farm under the Qiaoshan Forestry Bureau in Yan'an City, Shaanxi Province based on its official forest resource statistical data.
Forest resource statistical data is a critical dataset for forestry scientific research and forest resource management, encompassing information such as the spatial distribution, area, administrative divisions and their corresponding division codes of various forest types.
Such data covers multiple administrative and management tiers including national, provincial, county-level and forest farm levels.
Most existing forest resource statistical data is derived from either Type II Forest Management Inventory or Type I National Forest Inventory datasets, and serves as highly important statistical resources for forestry production activities.
