摘　　要：秦岭火地塘林区5种林分类型对冬季降雪的影响研究表明:冬季降雪量占全年雨量的6.38～8.16％;林分拦雪量占总降雪量的19.22～48.60％;针叶林和阔叶林的最大拦雪量分别为8mm和4mm;影响林地上雪的水平分布和雪量的主要因素为林分类型和降雪量及降雪类型。Describes the influence of snowfall distribution on different stands at Huoditang forest region in Qinling Mountain. The annual snowfall of whole winter was about 6.38~8.16% of annul precipitation, and the canopy interception of snowfall of forest stand was 19.22-48.60%.The maximum canopy interception of snowfall in either coniferous or hardwood forest stand was 8.0mm and 4.0mm respectively. The main factors affect the snowfall on forest land were found to be forest standtypes and snowfall and its types.
