摘要
热量和水分条件是林木生长最为重要的气候因素,它不仅决定着天然林的分布规律,而且对人工造林有极大的制约作用.利用祁连山区的数据资料,论述了水热条件与祁连山区造林成活率、林木生长量等的相关关系,并结合祁连山区造林成活率调查资料数据,分析了坡向与土壤含水量对造林成活率的影响.
Water and heat condition is the importance weather factor at a wood growth the forest which not only deciding regulation of distributing of natural wood, but also to afforest to have got the roughly function of tremendous system to artificial. Make use of the data that Qilian mountain area, and discuss relationship towards forestation live rate and wood growth measure of Qilian mountains, and combination the data of the forestation live rate investigate of the Qilian mountains, and analyze the slope face and the water contain of soil to influence forestation live rate.
