当前世界环境

本研究涉及盐林密度、物种多样性、基面积、IVI、生物量和碳储量。这项研究是在塔纳克布尔champaat附近的三个萨尔森林地点进行的。15种乔木的总密度在290 ~ 690 ind. ha . 1之间。森林树木基面积为50.92 ~ 78.84 m2 ha-1。萨尔林树种多样性在1.07 ~ 2.11之间。林木生物量和碳储量分别为473.3 ~ 786.8 ha-1和224.8 ~ 373.7 ha-1。从密度参数上看，各样点的优势种均为赤竹。与区域内及周边天然林相比，萨尔林的树密度略低。密度与生物量、碳含量呈显著正相关(p?0.05)。但杉木的树龄和大小的差异反映了不同立地间生物量和碳储量的差异。 Present study concludes that Sal forests in and around nearby villages were in degraded conditions due to anthropogenic pressure. Thus, the forests must be conserved through judicious management by providing proper scientific inputs for high biomass and carbon.
