摘要: 应用格局指数、聚集强度指数和集聚均数,研究了哈溪林区夏季封育和冬季封育草类青海云杉林优势种群空间格局的差异和形成原因。结果表明:青海云杉种群格局整体呈 聚集分布,不同封育季节种群格局对放牧干扰有不同的反应,夏季放牧对不同龄级种群格局的影响远比冬季放牧时的大;造成夏季封育和冬季封育草类青海云杉林不同龄级种群分 布格局差异的主要原因是不同季节放牧干扰所致。

Abstract: With the pattern index, intensity index and aggregated average, the difference and reasons of spatial distribution pattern of herbPicea crassifolia population under enclosed the hills for natural afforestation in summer and winter in Haxi forestry area were analyzed. The results indicated that the spatial pattern of Picea crassifolia population was aggregating distributed. The population spatial pattern in different seasons of the enclosed the hills for natural afforestation under graze disturbance had the different reaction, and summer graze to the different agegrade population spatial pattern effects was bigger than that of the winter graze. The main reason of the difference of spatial pattern about different agegrade population of herbPicea crassifolia forestry under enclose the hills for natural afforestation in summer and winter was graze disturbance.
