摘要
对天山北坡中山带草地类型复合结构与局部气候的影响问题进行了研究,通过环境因子与样地植被优势度进行相关分析,证明了地形和土壤基质引起的水热再分配,是复合结构形成的主要因素。对植物而言影响其生长的主导气候因子是湿度,辅助因子是气温和光照。
This experiment studied the rangeland complex form and climatic influence problem in the middle zone on northern slope of Tianshan mountains. The results from correlation coefficient between the preponderance degree and environmental factors indicate that humidity was major factor that affected rangeland complex form. The assistant factors were temperature and illumination intensity. this conclusion explained why there were different grassland types and landforms were similar in the middle part on northern slops of Tianshan.
