西藏色季拉山藓类植物与环境关系的研究
|
摘要
研究苔藓植物与不同环境因子之间的关系,对了解影响本地区苔藓植物的主要环境因子具有重要意义。利用色季拉山生态站监测数据,基于CCA排序方法对研究区内的藓类植物科、属、种与不同环境的关系进行研究。影响色季拉山藓类植物分布及其多样性的主要的环境因子是海拔、空气相对湿度、土壤温度、土壤pH值和光照强度。海拔梯度作为许多环境因子的综合反映,海拔梯度包含了降水量、温度、湿度、基质性质等生境因子,这些因子影响着植物群落的分布及物种多样性,是影响色季拉山藓类植物分布的主要环境因子。除上述因子之外,其它的环境因子如凋落物盖度、基质性质等对藓类植物也会产生一定程度的影响。结果说明,生境异质性和气候因子会直接或间接影响藓类植物的分布、多样性和生长状况。
It was important significance for us to research the relationship between mosses and different environmental factors and to understand the main environmental factors affecting mosses in this area. Based on Canonical Correspondence Analysis(CCA)sequencing method, the relationship between the family, genus and species of mosses in the study area and different environments was studied by using the monitoring data of the Nyingchi mountain ecological station. The result showed that the main environmental factors affecting the distribution and diversity of the mosses were altitude, air relative humidity, soil temperature, soil pH value and light intensity. As a comprehensive reflection of many environmental factors, altitude gradient included the habitat factors such as precipitation, temperature, humidity, matrix properties and so on, which affected the distribution of plant community and species diversity. In addition to the above factors, other environmental factors such as litter coverage, matrix properties, etc. also had a certain degree of influence on moss plants. The results indicated that Habitat heterogeneity and climate factors can directly or indirectly affect the distribution, diversity and growth of mosses.
