摘　　要： 对秦岭中龄华山松群落的林窗特征进行了分析.结果表明,秦岭华山松群落的林窗大小为25～160 m2;林窗形成方式中,人为采伐占63.5%;林窗制造者基部直径在10～20 cm的比例比较大,占50%;华山松群落的林窗内更新幼苗较多,林窗更新较林下更新好. In this paper, gap characteristics of middle-aged Pinus armandii community are analyzed preliminarily. The results are as follows ： （1）The gap area of P. armandii community is between 25-160 m^2 artiffcial cutting ,which occupied 63.5%,is a familiar gap methods ; The root diameter of gap maker is between 10-20 cm ,which occupied 50% of the tatal. （2） There are more seedings in the gap than under the forest ,so the gap generation is better than that of under the forest.
