大型海藻类光合无机碳利用研究进展

, 2001
概述了大型海藻类光合作用无机碳利用近年来的研究进展。大型海藻类除能利用 CO2作为光合作 用外在无机碳源外,许多大型海藻还能利用 HCO3- 作为光合作用外在碳源。HCO3- 的利用主要为胞外 CA 催化的 HCO3-与 CO2的相互转化及 HCO3-的直接吸收两种方式。在三类大型海藻中无机碳利用各有其独 , 特性 ...

自然降雨下紫色土坡耕地碳源添加对碳迁移及固碳的影响机制

Shuitu Baochi Xuebao
目的紫色土土壤退化形势严峻，水体流失严重，土壤增碳固碳困难，为探究碳源添加对紫色土坡耕地碳固存的影响。方法以四川紫色土坡耕地为对象，在10°紫色土坡耕地设置不施肥(CK)、化肥+秸秆还田(T1)、化肥+秸秆生物炭(T2)、化肥+牛粪(T3)、化肥+有机改土基质(T4)、化肥+生物炭牛粪菇渣堆肥(T5)6种处理，每种处理重复3次。分析降雨量及不同碳源处理下径流、泥沙、碳质量分数的变化特征。结果1) 降雨量＞30 mm，短时强降雨(16.1 mm/h)可促使地表径流的产出。碳源添加可显著减少地表径流量(p ...

不同森林植被下土壤水溶性有机碳研究

Shuitu Baochi Xuebao, 2004
在我国亚热带采集了常绿阔叶林、马尾松林、杉木林和毛竹林土壤,分析了土壤总有机碳和水溶性有机碳含量。结果表明:土壤总有机碳含量常绿阔叶林和毛竹林显著高于杉木林和马尾松林。土壤水溶性有机碳含量毛竹林显著高于杉木林,极显著高于马尾松林,阔叶林和杉木林也显著高于马尾松林。水溶性有机碳占总有机碳比率以杉木林最高,达1 26%(25℃)和1 82%(100℃),马尾松林最低,仅0 78%(25℃)和1 30%(100℃)。马尾松林、杉木林和毛竹林土壤水溶性有机碳与土壤总有机碳含量间的相关性均达显著水平 ...
