黑荆树是一种优良速生树种。1983年以来在福建省漳州市各县大力推广,现具有一定规模。为了正确评价生产单位的经营水平,笔者砍伐样木333株编制了一元和二元材积表,其模型为: 1.v=a(D+K)~b 2.v=a(D+K)~b·H~c 所编制的一元、二元材积表,经检验总体材积精度均在95％以上,使用二元材积表单株材积精度为85％,精度较高,具有一定的实用价值。 Black Wattle is a good fast-growing tree species. Since 1983, Zhangzhou City, Fujian Province to vigorously promote the county, now has a certain scale. In order to correctly evaluate the operating level of the production unit, I cut down the sample-like 333 strains prepared a one yuan and two yuan volume table, the model is: 1.v = a (D + K) ~ b 2.v = a (D + K) ~ b · H ~ c prepared by the unitary, binary volume table, the test volume accuracy of the overall volume of 95% or more, the use of binary volume table volume accuracy of 85%, higher accuracy, has a certain practical value.
