摘　　要：新疆9个代表站点实测资料显示,新疆雪密度变化有明显稳定期和不稳定期之分,稳定期雪密度随时间呈斜率为0.0059的直线变化;进一步通过对新疆29个有雪密度观测资料的气象站40a(1964-2003年)气象资料进行聚类和回归分析,结果表明降水、雪深、大风、吹雪日数等因子与稳定期雪密度有显著或极显著正相关关系,从而建立了雪密度估算的气候模型。利用雪密度气候模型,以79个站雪密度为基础,采用mapgis65,结合地形、高程和卫星遥感数据,完成了新疆稳定期雪密度的空间分布图,该图是可用于计算的电子图集,可随时提取新疆及其任意区域的雪密度。Based on the snow density data from 1964 to 2003 in 29 meteorological stations, the temporal and spatial distribution of snow density in Xinjiang Uigur Autonomous Region was analyzed by using clustering and regression methods. The results showed that the snow density was significantly positively related to the precipitation, snow depth, strong wind, days of blowing snow and temperature. From this relationship, a model was established between snow density and above climatic factors. By using mapGIS65 and remote sensing data,the map of the snow density during the stable period was made.
