P426.63; [目的]融雪径流是干旱内陆河流重要的补给组成.季节性积雪对环境变化极为敏感,研究影响季节性积雪积累与融雪过程的关键因素并进行调控,对变化环境下流域安全与水资源可持续利用具有重要意义.[方法]通过对新疆天山北坡乌鲁木齐河流域试验区2017年11月—2018年2月有无遮蔽条件下(林冠下、开阔地)季节性积雪层分层物理特性进行观测,分析季节性积雪层分层物理特性差异特征.[结果]①观测期开阔地气温略高于林冠下气温,而林冠下相对湿度高于开阔地;②林冠下积雪平均深度小于开阔地,分层积雪中深霜层与粗粒雪层深度比例较大;③林冠下与开阔地分层积雪密度垂直廓线变化特征基本一致,雪层密度从新雪层向下逐渐增大,至粗雪层(开阔地)与中粒雪层(林冠下)达峰值;④林冠下与开阔地分层雪温和分层液态含水率均自...
