Tropical Sal forests are gaining wide recognitions due to its multifarious significance. An estimation of vegetational structure and biomass would be helpful for evaluating both productivity and sustainability of the forest ecosystems. Information regarding vegetational biomass, litter mass and fine root biomass, and overall dry matter dynamics are very limited. Therefore, the present work deals the vegetation biomass influenced by four different site quality of Sal dominating tropical deciduous forest of Chhattisgarh, India. The current study provides a framework under which all vegetational attributes can be quantified under varying site quality which is modified by different seasons. Our study revealed a significant increase in vegetational attributes and biomass as per increasing quality of sites. The density value (individuals/ha) and basal area (m2/ha) of tree, sapling and seedling in different sites were ranged from 710 to 1010, 2000 to 2500, 9750 to 14,500 and 33.5 to 46.8, 0.32 to 0.33, 17.96 to 21.43, respectively. The total biomass varied from 187.39 to 383.46 t ha−1. The fine root and forest floor biomass varied between 2.44 and 4.20 t ha−1, and 2.32 and 2.83 t ha−1, respectively among different sites and seasons. The total litter fall varied from 4.18 to 5.69 t ha−1 yr−1 across the site quality. It reflected that highest value of forest floor, litter floor and fine root biomass were seen in site quality (SQ) SQ-I followed by SQ-II, SQ-III and SQ-IV, respectively in different seasons. A great synergy exists among site quality, stand structure and biomass which surely affect ecosystem structure and its functions. Seasonal impacts are another factor that regulates vegetational statistics, forest floor, fine roots and pattern of litterfall in varying site qualities. Thus, a management implication is needed to understand site quality variation which entirely affects vegetational structure and biomass pattern that would help in strengthening sustainable forest management program.

印度中部热带萨尔混交落叶林的立地质量和植被生物量

热带萨尔森林由于其广泛的意义而获得了广泛的认可。估算植被结构和生物量将有助于评估森林生态系统的生产力和可持续性。有关植被生物量,凋落物质量和细根生物量以及总体干物质动态的信息非常有限。因此,本研究处理了印度Chhattisgarh热带落叶林中Sal的四种不同站点质量对植被生物量的影响。当前的研究提供了一个框架,在该框架下,可以根据不同季节的场地质量在不同的场地质量下对所有植被属性进行量化。我们的研究表明,随着地点质量的提高,植被属性和生物量显着增加。2 / ha)的树,幼树和幼苗在不同位置的范围分别为710至1010、2000至2500、9750至14,500和33.5至46.8、0.32至0.33、17.96至21.43。总生物量从187.39至383.46t ha -1不等。在不同地点和季节之间,细根和林地生物量分别在2.44至4.20 t ha -1和2.32至2.83 t ha -1之间变化。凋落物总数从4.18到5.69 t ha -1  yr -1不等整个网站的质量。结果表明,在不同季节中,林地,凋落物和细根生物量的最高值出现在站点质量(SQ-I)之后,分别是SQ-II,SQ-III和SQ-IV。场地质量,林分结构和生物量之间存在巨大的协同作用,这肯定会影响生态系统的结构及其功能。季节性影响是调节植被统计数据,森林地面,细根和凋落物形态在不同场地质量中的另一个因素。因此,需要一种管理意义来理解站点质量变化,该变化会完全影响植被结构和生物量格局,从而有助于加强可持续森林管理计划。
