摘要

Climatically the Chapursan Valley (Gilgit) is classified as alpine region but floristically it may be characterized as a part of Eastern Irano-Turanian region. Presence/absence data were used to classify and ordinate for both sites and species. DCA axes 1 and 2 were used for data interpretation. The relationships between soil characters and DCA axes 1 and 2 were determined using Spearman Rank correlation. Cluster analysis identified 5 vegetation types viz., crassulescent steppes, chamaephytic steppes, erme, moist sub-alpine pastures and riverine pseudo-steppes. These vegetation types have been discussed in the context of topographic and edaphic heterogeneity.
