Comparative studies on carbon storage and litterfall dynamics between secondary and primary mangrove communities in Zhanjiang,Guangdong Provinces,China [PDF]
, 2014 通过群落调查、异速生长法计算以及样品测定,分别对2010~2011年期间广东湛江高桥红树林生态系统中次生桐花树和原生木榄群落的植物和土壤储量进行了计算,并利用掉落物收集筐对掉落物动态进行了比较研究。研究结果表明,高桥桐花树与木榄群落的植物碳库(以C计,下同)分别为(51.16±12.06)x106g/HM2和(38.52±6.94)x106g/HM2,地上部分明显高于地下部分;土壤碳库分别为(111.86±7.96)x106g/HM2和(106.13±11.12)x106g/HM2,明显高于植物碳库 ...

ABSORPTION AND ACCUMULATION of HEAVY METALS IN AEGICERAS CORNICULATUM MANGROVE FOREST IN THE ESTUARY of THE JIULONG RIVER IN FUJIAN [PDF]
, 1996 探讨了福建九龙江口桐花树红树林对Cu、PH、zn、Cd、Mn元素的吸收、累积及分布.结果表明：该林地土壤5种元素的储量关系为Mn＞zn＞PH＞Cu≥Cd；植物体不同部位，各元素含量有着明显的差异，含量范围分别为CH1.51~5.70、Pb1.30~10.70、zn18.0~100.1、Cd0.04~0.23和Mn15.5~237.5（W/10-6）；植物对土壤元素的富集系数大小依次为Cd＞zn＞Mn＞Cu＞PH；群落现存生物量中，Cu、Pb、zn、Cd、Mn元素的现存累积量分别为16.56、63.30 ...
