1973年我们在东方红林业局工作时,曾提出“象限样地”调查法,就地进行了试验;1974年在得耳布尔林业局工作时,又进行了验证。从试验结果看,采用“象限样地”估测蓄积,具有精度高、效率快、简便易行等特点,比常规样地或角规观测有其优越之处。为了取得同志们的帮助,使之得到改进,现作简单介绍,希望给予批评指正。
In 1973, when we worked at Dongfang Huanghuang Forestry Bureau, we put forward the “quadrant plots” survey method and conducted experiments on the spot. In 1974, when we worked at the Board of Forestry in T’er Erhur, we carried out verification. From the test results, using the “quadrant-like plot” to estimate the accumulation, with high precision, fast efficiency, simple and easy to use, etc., than the conventional sample or angular gauge observation has its advantages. In order to obtain the help of comrades and make improvements, we briefly introduce them and hope to give criticism and correction.
