This dataset comprises statistics on the stock volume of timber forests by tree species, covering middle-aged, near-mature, mature, and over-mature forests at the county and district level in Shaanxi Province during the agricultural regionalization period from 1978 to 1985. The recorded and statistically covered contents include administrative code, data year, description, serial number, total stock volume of all tree species, stock volume of spruce-fir, cypress, hemlock, Chinese red pine, Huashan pine, Masson pine, larch, Chinese fir, oak, birch, poplar, black locust, and miscellaneous broad-leaved trees; total stock volume of middle-aged forests across all tree species, along with stock volumes of middle-aged spruce-fir, middle-aged cypress, middle-aged hemlock, middle-aged Chinese red pine, middle-aged Huashan pine, middle-aged Masson pine, middle-aged larch, middle-aged Chinese fir, middle-aged oak, middle-aged birch, middle-aged poplar, middle-aged black locust, and middle-aged miscellaneous broad-leaved trees; total stock volume of near-mature forests across all tree species, with stock volumes of near-mature spruce-fir, near-mature cypress, near-mature hemlock, near-mature Chinese red pine, near-mature Huashan pine, near-mature Masson pine, near-mature larch, near-mature Chinese fir, near-mature oak, near-mature birch, near-mature poplar, near-mature black locust, and near-mature miscellaneous broad-leaved trees; total stock volume of mature forests across all tree species, plus stock volumes of mature spruce-fir, mature cypress, mature hemlock, mature Chinese red pine, mature Huashan pine, mature Masson pine, mature larch, mature Chinese fir, mature oak, mature birch, mature poplar, mature black locust, and mature miscellaneous broad-leaved trees; total stock volume of over-mature forests across all tree species, as well as stock volumes of over-mature spruce-fir, over-mature cypress, over-mature hemlock, over-mature Chinese red pine, over-mature Huashan pine, over-mature Masson pine, over-mature larch, over-mature Chinese fir, over-mature oak, over-mature birch, over-mature poplar, over-mature black locust, and over-mature miscellaneous broad-leaved trees. This dataset provides data support for the statistical work of timber forest stock volume by tree species composition at the county and district level in Shaanxi Province.
