| 摘 要： | 选用西藏色季拉山2007年藏药材的野外调查资料以及自动气象站观测的气象数据,探讨了濒危藏药材的基本分布状况及其生长的区域气候特征。研究表明:从藏药材的分布来看,随着海拔高度的升高,藏药材的植株高度、盖度以及多度都呈现基本下降的趋势,药材属性与山体坡向的关系随着药材种类的不同而有所区别。从药材生长区域的总体气候特征来看,山顶降水量、相对湿度基本大于西坡和东坡,东坡基本大于西坡;山顶平均气温、地面温度低于西坡和东坡,东坡高于西坡;山顶风速基本大于西坡和东坡,西坡大于东坡;西坡以东风为主,山顶以南风为主,东坡以静风为主;随着海拔高度的升高,降水量逐渐减少,相对湿度、风速增加,温度降低;静风(东风)频率减小(增加);南风、SSW风频率随着季节不同而增加或者减小;东坡、西坡的温度(风速)随海拔高度的升高而降低(增大),东坡、西坡的降水量、相对湿度、风频率随着海拔高度的升高呈现基本相反的变化。 |

| Abstract: | There are growing abundant and unique natural medicine herbal products over the Tibet plateau due to its special geographical, climatic and environmental conditions. Because of its original theory and processing technology, Tibetan medicine has a pretty good therapeutic effect on a variety of diseases, appearing to be of unique therapy value and large application potential. The growing of Tibetan plateau herbal products is closely related to its special climatic and environmental conditions and show great vulnerability. Mt.Seqilha is located in the southeast of Tibet, namely the Nyingchi area, belonging to the Nyainqentanglha Range. Vegetation types are much more than other regions at the same latitude. Much research has been analyzed ecological characteristics of vegetation of the alpine frigid zones across mountainous areas such as Mt.Seqilha, with discussing biological characteristics and application potential of some medicine herbal products. But only a few studies focus on climatic characteristics of the growing of herbal products, even fewer on variations in wind direction and vertical distribution of meteorological variables along with different aspects of mountains. This paper is to derive basic distribution of endangered herbal products and regional climate characteristics of its growing with varying aspects and altitudes on the basis of field investigations and meteorological observations around the Mt.Seqilha region in the year 2007. Results showed that in general, the average height, coverage and abundance of herbal products are gradually declining with increasing altitude. The relationship between herbal products and slope varies greatly with plant categories. Considering general climate characteristics of herbal products growing, the precipitation and relative humidity on the summit of the mountain are essentially larger than that facing west and east; the east aspect is larger than the west aspect. The wind velocity on the summit is generally larger than that facing west and east; the west is larger than the east. Regarding wind directions, the east wind dominates the west aspect of the mountain, and the south wind predominates on the summit. The east aspect shows calm wind. With increases in altitude, the precipitation, relative humidity and temperature decrease but wind speed increases. Clam wind frequency decreases but the east wind frequency increases. The south wind and SSW frequencies vary with seasons. The temperature for the east and west aspects increases with elevation but the wind speed decreases. The precipitation, relative humidity and wind frequency over the east and south aspects show opposite trends of the temperature. |
