摘要
对9年生柳杉人工林的26个样地调查其立地条件与生长量之间的关系,初步研究表明:当土壤疏松层厚于30cm时,柳杉生长良好,浅于20cm时,柳杉生长不良;柳杉生长受地形影响,在山洼、山谷处生长最好,山坡、山顶、山脊则较差。
The relation between site condition and growth increment of
9-year-old Cryptomeria fortunei plan- tations has been surveyed on 26 sample plots.The
preliminary research indicates that C.fortunei grows well when the loose layer of its soil is
thicker than 30cm;it grows poorly when the loose layer is more shallow than20cm;and its
growth is affected by topography:it grows best on the low-lying mountain land or mountain val-
ley while it grows relatively poorly on the mountain top or mountain ridge.
