摘　　要：在青海省湟水及其支流的河谷地区,青杨人工林分布比较集中,生长情况差异很大,其中,河谷不同地形部位立地条件的差别,对杨树生长的影响表现十分突出。调查研究河谷地区不同立地类型青杨的生长规律,对认识青杨生物学和林学特性,提高杨树造林、营林技术水平具有重要意义。In the river valleys of Huangshui and its tributaries,the distribution of Populus cathayana plantations is relatively concentrated,and the growth situation is very different.Among them,the difference in site conditions of different terrain parts in the valley has a prominent effect on the growth of poplars.It is of great significance to investigate and study the growth patterns of different types of Populus cathayanain the valley area,to understand the biology and forest characteristics of poplar,and to improve Populus cathayana afforestation and forest management techniques.
