The Birch-Aspen forest is the pioneer communities soon after clearcutting or fire of broadleaved Korean Pine forest that will be recovered through its transiting stage in the Xiaoxingan Mountains.The testing stands locate at the Liangshui Natural Reserve from 360m to 400m. This paper demonstrates the relationships between the microclimate features in Birch-Aspen forest and the natural recruitment as well as growth of Korean Pine according to the 3 years microclimate observations and recruitment investigations from 1983 to 1985. Compared with the virgin communities, the Birch-Aspen forest has the ecological factors which has changed a lot and become more adaptable to the recruitment and growth of Korean Pine whose 30 yearst recruitment seedlings under their canopies have the evenly distributed age structure and rejuvenating characteristics of the Korean Pine forest are obvious. The 20 years Korean Seedlings under Birch-Aspen canopies have their mean height and ground diameter 4--5 times of those same age seedlings under virgin Korea Pine forest. We should fully take the great advantages of natural recruitment potential to recover the Korean Pine forest and also show concern to the artificial recruitment at the poor site of Birth-Aspen forest or cut some of the upper broadleaved trees on time in order to create a better condition under canopies.

小兴安岭林区,杨桦林是阔叶红松林皆伐或火烧后首先发生的先锋群落,是恢复红松林的过渡阶段。 试验地设在东北林业大学凉水自然保护区,海拔360—400米。于1983年至1985年进行三年小气候观测和林下更新调查,阐述了杨桦林下的小气候特点与红松天然更新及生长的关系。杨桦林与原生群落相比较,其林下各生态因子发生了显著变化,较适宜红松的更新及生长;30年生的杨桦林下红松天然更新每公顷达4000多株,而且幼苗幼树在年龄上分配比较均匀,恢复红松林的趋势很明显;林下20年生红松幼树平均高是原始林下同龄幼树的4—5倍,地径也增粗4—5倍。 恢复红松林应发挥天然更新的巨大潜力。对杨桦林下红松天然更新不好的地段辅助以人工更新,并适时疏伐上层阔叶树,为林下幼树创造更适宜的生长条件。这是加速杨桦林恢复为阔叶红松林的重要途径之一。

The main teaching building of Northeast Forestry University was built in 1956 and came into use. By our observation, so far,the building is working well. The main building has been bnilt for 30 years, nevertheless, its dynamic property parameters——natural frequency,normal modes,damping are unknown yet.We carried out a study on its dynamic property parameter with a surrounding random excitation;here, its (1st)natural frequency,(1st) normal modes and damping ratio are given in this paper. We find its account as a reference in the maintenance and use of the main building preventing it from the seisin damage and its life-span estimation.

东北林业大学教学主楼于1956年建成使用。经观察,到目前为止,教学楼工作状态良好。但是,自主楼建成至今已有三十年,它的动力特性参数——固有频率、振型、阻尼等参数还不知道。 本文通过环境随机激振,对教学主楼的动力特性参数进行了研究,给出了主楼南北弯曲振动的一阶固有频率、一阶主振型及阻尼比,这对于主楼的使用维修,防止地震危害以及估计主楼的寿命将具有参考价值。
