摘要: <正>对宁镇丘陵区栎、马尾松、杉木、毛竹林地和草地土壤腐殖质样品,做了组分分析、元素分析、光密度测定和红外光谱分析。结果表明:北亚热带黄棕壤地带的土壤腐殖质,在化学结构、组成和性质上,都反映气候带的过渡特点,但在不同植被影响下,也表现结构发育程度以及各种基团数量上的差别。土壤HA/FA比值的序列是竹>草>松>栎>杉,而土样胡敏酸的C/H比值序列为草>竹>松、栎>杉。结合其它分析资料,可以认为草地和竹林地的腐殖质质量最优,而杉林地的最差。森林土壤腐殖质化学特征的研究,可以作为森林生态系生物循环定量研究的补充。

Abstract: In Nanjing-Zhenjiang Hills, soil humus samples from under oaks, pine, Chinese fir,hairy bamboo forests and herb were adopted for fractionation analysis, chemical element analysis, light density measurement and infra-red spectral analysis. It turned out that soil humus in the yellow brown soil zone of northern subtiopics showed that the interim ehracters on their chemical structure, composition and properties relevant to the transitional zone of climate, but they somewhat varied on developing degree of chemical structure and quantity of groups under the influence of various vegetations. It might be accepted that the quality of soil humus under herb or bamboo stand is the best, and that under Chinese fir stand is the worst.
