一、雪岭云杉的分布及生长情况雪岭云杉Picea schrenkiana是天山北坡森林带的主要组成树种,除东段哈密林区巴尔库山、哈尔雷克山北坡2,300(2,400)米以下与西伯利亚落叶松Larix sibirica形成混交林外,其他各段几均为纯林.其分布严格地限制于海拔1,500—2,700(2,800)米的中山带、坡度为30—40°的阴向(西北或东北)陟谷坡上.这种分布,主要与山区气候条件有关.因中山带的阴坡面,气候温涼湿润,温差变化不太剧烈,
First, the distribution and growth of snowy spruce Picea schrenkiana Spruce Picea schrenkiana is the main component of the Tianshan northern slope of the forest belt, except for the eastern section of the Barkhul Hill District, Harlek North 2,300 (2,400) meters The following mixed with Larix sibirica Siberian forest, most of the other sections are pure forest, its distribution is strictly limited to 1,500-2,700 (2,800) meters above sea level with a slope of 30-40 ° negative (northwest Or northeast) 陟 valley slope .This distribution, mainly with the mountain climate conditions.Because of the Zhongshan slope, the climate is cool and humid, the temperature change is not too violent,
