我们为什么要歌唱？促使人类第一批歌者打开喉舌的驱动力又是什么？这本有趣的著作正是基于这样的问题开始的。依次登场的重要人物有：发明五线谱的阿雷佐的圭多修士（Guido of Arezzo）;拥有惊人音色的阉人歌手法里内利（他的财产及艺术收藏不可计数）;罗西尼是一个激发想象力的大容器,因为歌手在他那儿可以即兴唱出美妙绝伦的华彩;威尔第呢,则更愿意歌者忠实地循着谱面前行……展开更多

The vegetation was quantitatively analyzed on four different aspects i.e., east, west, north and south. Results of the study indicated that across the aspects, Anogeissus latifolia was dominant in tree, sapling and seedling layers in all the aspects, except north aspect where Pinus roxburghii and Terminalia tomentosa were dominant in tree and seedling layers, respectively. The highest tree layer density （380 plant.ha^-1） was recorded on south aspect and lowest （260 plant.ha^-1） on west aspect. In shrub layer, highest density was on east aspect （1790 plant.ha-1） and lowest on west aspect （970 plant.hal）. Tree and shrub layer diversity ranged between 0.846 to 1.710 and 1.943 to 2.847, respectively. The relative lopping intensity （%） was higher in Anogeissus latifolia （45%- 57% as compared to 4%-33% in other species） which is the most important tree species on all aspects, except north aspect. The present study also reveals that if the current rate of exploitation continues, the species like Anogeissus latifolia may be replaced by other species and drastic changes may occur in species composition and regeneration of the forest. The anthropogenic pressure, aspect and soil nutrients have caused changes in regeneration status and species composition of forests.展开更多
