以营林为基础是我国林业建设的根本方针,而营林调查设计又是科学营林的基础。过去,我国造林保存率低,森林经营管理差,在一定程度土与缺乏调查设计,未认真贯彻经营方案有关。为了帮助调查设计人员和基层林业工作者系统了解营林调查设计的内容和具体作法,我们特请王永安工程师主持了这一讲座,较系统地介绍营林调查设计工作。讲座共分四讲:一、种苗及调查设计;二、立地调查和分类;三、造林典型设计;四、林分经营管理设计。
Based on silviculture, it is the basic principle of forestry construction in our country, and the investigation and design of silviculture is the basis of scientific silviculture. In the past, the preservation rate of afforestation in our country was low and forest management was poor. To a certain extent, the soil was related to the lack of investigation and design and the failure to earnestly implement the management plan. In order to help survey designers and grassroots forestry workers systematically understand the contents and specific practices of silvicultural investigation, we specially asked Mr. Wang Yongan to host this lecture and give a systematic introduction to the survey and design of silviculture. The lecture is divided into four lectures: First, seedlings and survey design; Second, site investigation and classification; Third, typical design of afforestation; Fourth, management design.
