山Shimagare（2395米）位于八岳死火山群北方的丘陵之一，最高峰是山。Akadake（2899 m.），在长野县，距离130公里。西北从东京。在山的西南缓坡的深绿色中。Shimagare山被亚高山针叶林覆盖，从远处可以清楚地看到几条平行的白色条纹，这座山因其明显的地貌而被命名为“死树带山”（照片）。1、2和图1）。植被由几个森林单元组成，每个森林单元都有一个序列排列，从高处的非常年轻的树木后代到过熟和死亡的冷杉和冷杉树。玛丽西在较低的部分，就像瓦格纳的边界削减的自然形象”）（图2）。这些白色条纹是这些针叶树的死树干的密集林（照片3），它们将在几十年内向上移动。Okubol~>、Yoshida和Yamanouchi 12>已经从林业的角度对森林进行了调查。他们收集了大量关于树木大小、密度和生长的初步信息，并试图讨论死树带的起源和转移，尽管这是推测性的。因此，这些问题可能是值得更精确的生态学和生理学调查的起源和维持这样的森林单位排列，特别是在干物质生产的基础上，因为这些调查将带来许多新的发现的自然特性的种内和种间竞争和植物演替，作者和他们的合作者4>，5>，6>，7>从理论上和实验上研究了其中的基本原理，并对日本中部亚高山的顶极植被进行了研究。
Mt. Shimagare (2395 m. above the sea) is one of the hills in the northern part of Yatsugatake dead volcano group, of which the highest peak is Mt. Akadake (2899 m.), in Nagano Pref., at a distance of 130 km. NW W from Tokyo. In the dark green of the gentle southwest slope of Mt. Shimagare covered with subalpine coniferous forest, several whitish stripes horizontally running in parallel with each other can be seen in a distant view so distinctly that the mountain has been named "mountain with dead trees strips" according to its conspicuous physiognomy (Photo. 1, 2 and Fig. 1). The vegetation consists of several forest units, each of which has a serial arrangement from very young tree offspring in higher part up to overmatured and dead trees of Abies Veitchii and A. Mariesii in lower part, just as the natural image of Wagner's border cuttings") (Fig. 2). The whitish stripes are the dense stands of dead tree trunks of these conifers (Photo 3), and they will shift upwards in decades. Okubol~>, Yoshida and Yamanouchi12> have already surveyed the forests from the viewpoint of forestry. They collected a lot of preliminary informations on the size, density and growth of trees, and tried to discuss the origin and shifting of the dead trees strips, though rather speculatively. Therefore, these problems might be well worthy of more precise ecological and physiological investigations into the origin and maintenance of such forest unit arrangement, especially on the basis of the dry matter production') of the trees, because these investigations will bring many new findings about natural features of intraand interspecific competitions and of plant succession, of which fundamentals have been studied theoretically and experimentally by the authors and their co-workers4>, 5>, 6>, 7>, and about the climax vegetation in the subalpine of central Japan.
