以天山中部天然雪岭云杉林空气负离子为研究对象，利用负离子测定仪对不同海拔、不同林分、不同时段负离子浓度进行检测，并以乌鲁木齐、乌拉泊负离子浓度做参照，探讨了不同条件下其空气负离子浓度水平及变化趋势。结果表明：天山雪岭云杉林具有较高浓度的空气负离子资源，平均浓度达1800个／cm^3，是生态旅游开发和人居休闲的理想地区；天山森林空气负离子浓度随着海拔呈现先上升后下降的趋势，最高浓度在海拔2200m左右；不同林分空气负离子水平日变化规律不同，幼龄林浓度始终维持在较高水平，变化趋势不明显，中龄林和成熟林具有相似的变化趋势，都是随着时间变化逐渐升高，一般下午达到最高水平。%Taking the Aeroanion Resources in Tianshan Forest of Pinaceae Schrenkiana as research object, by using of the Aeroanion mensurate instrument, we tested all the concentration of Aeroanion in different elevation, forest age and time, at the same time, with the reference in Urumqi and Wulabo area. And the aeroanion concentration level and its change trend in different conditions have been explored. The result showed that the Tianshan Forest of Pinaceae Schrenkiana has a high level of aeroanion resource, and its average concentration is 1800 unit/cm3, so this area is an idea ecological tour development and human rest; along with rising of elevation, the aeroanion concentration ascend first and descend later, the highest con- centration is about in 2200m; Daily variation trend is different for different forest age, the young age forest has a higher con- centration all the time, and its variation trend is not obvious. The middle age and mature age forest have same variation trend, the concentration is becoming higher by the daily time, and the highest level appeared in afternoon.
