在森林调查中采用模拟样地进行抽样调查,是近年来新兴起来的一种调查方法。我国有些单位对这种方法进行了多次研究和实验工作,并取得了一定成果和经验。本刊1977年3期和1978年4期曾先后发表了《模拟样地抽样调查法》及《象限模拟样地的初步探讨》两篇文章,阐述此种方法精度高、速度快、简便易行和适应性强等特点。但亦有不少从事该项研究和实际工作的同志对此持有不同见解,并提出了一些问题和意见。为了把模拟样地调查法的研究和实验引向深入,使其不断提高和日臻完善,本刊决定自本期起开展“关于模拟样地森林调查法”的问题讨论,希望从事本项研究、教学和生产工作的广大读者,踊跃来稿,积极参加讨论。本期发表下列两篇文章,做为讨论的开端。
The use of simulated samples in forest surveys to conduct sample surveys is a new and emerging method of investigation in recent years. Some units in our country have conducted many research and experimental work on this method and have achieved certain achievements and experiences. The articles published in 1977 3 and 1978 4 has published the “sample survey of analog sample” and “quadrant simulation plots of the initial discussion of” two articles, described the method of high precision, fast, simple and easy And adaptability and other characteristics. However, many comrades engaged in the research and practical work hold different views on this issue and have put forward some questions and opinions. In order to divert the research and experiment of analogue survey method to in-depth study and make it continuously improve and perfect, we decided to carry out the discussion on the issue of “Law on Simulated Sampled Forest Investigation” from this issue, hoping to engage in this research, Teaching and production of the majority of readers, enthusiastic contributions, and actively participate in the discussion. This issue of the following two articles, as the beginning of the discussion.
