陕西省延安市宝塔区2005年二类调查森林资源统计数据宝塔区各林种面积蓄积结构统计表

本数据记录了陕西省延安市宝塔区森林资源统计数据中宝塔区各林种面积蓄积结构统计表的统计单位、林种、活力木总蓄积量、有林地面积合计、面积小计、蓄积小计、幼龄林面积、幼龄林蓄积、中龄林面积、中龄林蓄积、近熟林面积、近熟林蓄积、成熟林面积、成熟林蓄积、过熟林面积、过熟林蓄积、疏林面积、疏林蓄积、灌木林面积等记录。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 records the statistical units, forest categories, total growing stock volume of live trees, total area of closed forest land, subtotal area, subtotal growing stock volume, young forest area, young forest growing stock volume, middle-aged forest area, middle-aged forest growing stock volume, near-mature forest area, near-mature forest growing stock volume, mature forest area, mature forest growing stock volume, over-mature forest area, over-mature forest growing stock volume, sparse forest area, sparse forest growing stock volume, and shrub forest area from the area and stocking structure statistics table of each forest category in the forest resource statistical data of Baota District, Yan'an City, Shaanxi Province. Forest resource statistics are critical data for forestry scientific research and forest resource management, including information such as the spatial distribution, area, administrative divisions and their division codes of different forest types. Forest resource statistics cover multiple levels including national, provincial, county-level and forest farm levels. Most of the current forest resource statistics are derived from second-class forest inventory (forest management inventory) data or first-class national forest inventory data, and serve as highly important statistical materials for forestry production.
