Abstract:: The shrub which distribute in the Tianshan Mountain spruce forests offline is one of important plant bush fallow types of Tianshan Mountains and is a relatively stable ecosystem playing an important role in the process of soil and water conservation. In this paper, six common shrubs spotted in survey plots which had been set in the western, eastern and middle areas of Tianshan Mountain were selected for the study. And the biomass of vegetative organs of six kinds of shrubs was measured using average standard method. Thereby, the differences in the distribution of six shrubs in the Tianshan Mountains and in the distribution of the three sections of different organs were explored. The results showed that: (1)the distribution of biomass of the same shrubs in the western, eastern and middle areas of Tianshan Mountain was different, the reason why biomass of western was significantly greater than the central and eastern area was that the condition of water and heat of western area was better than eastern and middle areas of Tianshan Mountains; (2) the biomass of six-kind of shrubs is in a descending order: Lonicera hispida Pall. (8 549 g/plant) > Cotoneaster melanocarpus Lodd. (7 943 g/plant) > Berberis atrocarpa Schneid. (7 880 g/plant) > Sabina pseudosabina (Fisch. et Mey.) Cheng et W. T. Wang (3 014 g/plant) > Spiraea tianschanica Pojark (2 837 g/plant) > Rosa spinosissima L. (2 615 g/plant); (3) there were differences in the distribution ratios of six kinds of shrubs, reflecting the shrub adaptability to habitat selection. The limb biomass of shrubs (53.30%) was greater than root biomass (27.32%) in the western area, the opposite biomass results were found in the eastern and middle areas. The results of this study may provide the scientific basis for the protection of the shrub vegetation and for restoration of degraded ecosystems in Tianshan Mountains.
