在森林资源清查中,生长量调查常用的临时标准地“解析木法”和“样木直径砍口法”已被一次性的森林资源调查广泛采用,然而在少林地区则难以实施。我市几个少林的丘陵县,林分主要树种为马尾松、杉木人工林和少量阔叶树,这些林分均属建国后的第二代林,龄组为中、幼林,年龄值较为清楚,根据上述特点。本人试图在这些地区结合抽样调查,“采用样木年龄法”调查生长量,并以此样木作为编制一元材积的样木。这样,不仅达到了样木双重利用的
In the inventory of forest resources, the temporary standard “analytical method” and “sample diameter timber cutting method” commonly used in the growth survey have been widely adopted by the one-off forest resource survey, but are difficult to implement in the Shaolin area. The main forest stands are Pinus massoniana, Cunninghamia lanceolata plantation and a few broad-leaved trees in the hilly county of several Shaolin in our city. These stands belong to the second generation of forest after the founding of PRC, and the age group is medium and young forest. The age value is relatively clear. According to The above characteristics. I have tried to combine sample surveys in these areas with the “Sample Wood Age Method” to investigate the amount of growth and use this wood as a sample preparation wood for a single volume. In this way, not only reached a double utilization of wood samples
