英文摘要	We studied diversity of tree-shrubs and productivity and carbon storage capacity of Leptadenia pyrotechnica (Forsk.) Decne in Indian Desert in three agro-climatic zone namely Arid western plain (AWP), Transitional plain of inland drainage (TID) and Transitional plain of luni basin (TLB) with a view to monitor the contribution of L. pyrotechnica in biomass production and carbon storage in arid areas. Population and basal area were greater for shrubs than for the tree species. The contribution of L. pyrotechnica in basal area was about 40%. Carbon content of L. pyrotechnica varied from 43.32 to 45.86% and 39.45 to 42.51%, whereas nitrogen content varied from 0.41 to 2.21% and 0.57 to 1.69% in oven dry stem and roots, respectively indicating relatively greater carbon and nitrogen in stem than in roots. The highest population of tree and shrubs was in TID and AWP, respectively but total basal area was highest in TLB zone. Species richness was highest for tree, whereas species diversity and evenness were highest for shrub in all agro-climatic zones. Species dominance was highest in AWP zone for both tree and shrubs. Plants of L. pyrotechnica were taller in TLB, thicker (collar diameter) in TIP and with highest numbers of tillers in AWP. Height (H) and collar girth (G) showed power relations (R-2 = 0.683, P < 0.001) with above-ground and compound relations (R-2 = 0.552, P < 0.001) with below-ground biomass. Both the above-ground and belowground biomasses were the highest in TLB and lowest in TIP zone. Root/shoot ratio was similar in AWS and TIP zones but was significantly greater (1.25) in TLB zone suggesting greater biomass allocation to roots. Conclusively, L. pyrotechnica has significant contribution in vegetation population, basal area and biomass production and showed greater biomass allocation to roots that help in stabilizing soil and sequestering carbon.
