宜昌市马尾松地径一元材积表编制

Preparation of Unitary Volume Table for Basal Diameter of Pinus Massoniana Lamb.in Yichang Prefecture

我们用2a时间实测活立木地径和胸径2500株,并按不同的径阶、不同的立地因子整理及汇总外业调查表,编制成《宜昌市马尾松地径一元材积表》,在实际工作中,它的编制将起到"填补材积表空白"的作用。二是依据伐桩鉴定林木蓄积的需要。近几年来,在处理滥伐、盗伐林木案件时,往往是盗伐、滥伐的林木已被运走或售出无法追回,只能调查到被伐的树桩。在这种情况下,利用该表为我们节省了大量的人力、物力以及时间。

We prepared a Unitary Volume Table for basal diameter of Pinus massoniana Lamb. Field in Yichang City by surveying on-site and D,B,H for 2 500 living trees within two years and by coordinating and consolidating the field working survey tables based on various diameter grade and site factors. Preparation of such a table will fill vacancy of volume tables during our effective operation. Besides, woods storing for identification of lumbered stakes require us to do so in recent years, when investigating such cases as denudation and unlawful felling of trees, it has always been the fact that the woods suffering denudation and unlawful felling have been transported or sold out and unrecoverable, in which event, only the stakes lumber could be found. In this case, this table may be utilized to save a large amount of human resources, material resources and time as well.
