摘要: 采用中国科学院沙坡头沙漠试验研究站1987~1997年物候连续观测资料,研究了我国主要荒漠灌木种在该地区的物候学特征,并分析了与温度、降水、光照、风速等环境因子的相关性,结果表明,均温与光照是这些灌木主要物候期的主导因子。通过聚类分析确立了3个萌动期物候类型、3个展叶期物候类型和4个开花期物候类型。研究结果对荒漠化地区人工植被建设和生物多样性迁地保护具有重要的意义.

关键词: 荒漠化地区, 荒漠灌木, 物候学特征

Abstract: About 300 species of plants have been introduced successfully to the s outheastern edge of the Tengger Desert since the establishment of Shapotou Deser t Research and Experimental Station in 1956.It is now a research base for large scale off site conservation of biodiversity.Based on successive observations m ade from 1987 to 1997,this paper studies the phenological characteristics and the relationship between the phenolo gical period of shrubby species and environmental factors.The results show that the mean temperature and accumulated sunshine duration are the dominant factors of the main shrub phenological period,but the precipitation is closely related t o the resurrection,and the wind speed also plays an important role in leaf expan sion.The classification of 30 shrubby species by clustering analysis according t o the environmental factors of resurrection and leaf expansion,4 phenological ty pes of shrubby blooming are identified.The research results of this paper are of an important significance to the establishment of artificial vegetation and off site conservation of biodiversity.

Key words: desertification region, desert shrubby species, phenological character istics
