【摘要】 本文研究了广西北海大冠沙白骨壤群落的现存生物量。测定结果表明:白骨壤群落的生物量为5272.2g/m~2,其中地上部分为2690.2g/m~2,地下部分为2582.0g/m~2.地下部分中94.8%的根分布于地面以下0～60cm 层。由于不同滩面的环境因素差异较大,位于不同滩面白骨壤群落的生物量也有所不同,位于内滩、中滩、外滩的群落生物量分别为11424.0g/m~2、2585.3g/m~2、1806.3g/m~2。更多还原

【Abstract】 In this paper the phytohiomass of Avicennia marina community in Daguansha Bay of Guangxi has been studied,The results of measurement were as follows:standing crop of A.marina community was 5272.2g/m~2,among them the biomass of above-ground part was 2690.2g/m~2 and the under-ground part was 2582.0g/m2;94.8 per cent of under-ground roots distribute in upper 60cm stratum of soil.Biomass of A.marine increases from shore to inland,the biomass of shore area,middle area,and inland area are 1806.3g/m~2,2585.3g/ m~2,11424.0g/m~2 respectively.The regional variation of organic matter and other soil properties are contributing factors to the uneven distribution of biomass of A.marina from shore to inland.更多还原
