| 1 | 南方网纹红土多元成因的粒度证据显示文摘对宣城、九江、泰和和赣州网纹红土粒度特征的研究表明: (1) 宣城和九江两地的网纹红土, 粒度均匀而细小, 不含>2 mm的砾石; >63 mm细砂粒的平均含量分别为0.30%和1.14%; 而10~50 mm粒组明显富集, 平均分别为34.65%和37.20%. 剖面上部黄棕色土的粒度频率分布曲线与北方黄土和下蜀黄土很相近; 其余各层的频率分布曲线与前者也有明显的继承性. 剖面各层石英颗粒粒度频率分布曲线十分一致, 与北方黄土和下蜀黄土有很好的可比性. 这些特征均反映了两地网纹红土明显的风成特性. (2) 泰和、赣州网纹红土粗颗粒含量较高; 各粒级组分在层次间变化明显; 10~50 mm 粒组富集不明显. 红土原样和红土石英颗粒粒度频率分布曲线与北方黄土和下蜀黄土缺乏可比性, 表现出明显的冲、洪积相特征. (3) 网纹红土成因的多元性反映了南方第四纪环境的多样性和复杂性. 风成特性网纹红土的存在为南方第四纪冰期风尘堆积提供了实物证据. 对这类红土分布区域的进一步调查和研究, 有助于揭示南方第四纪冰期大规模风尘堆积的南界. | 胡雪峰 朱煜 沈铭能 | 2005 | 科学通报2005，50，9： | 50 |
| 2 | Land Use-Related Changes in Soils of Hainan Island During the Past Half Century显示文摘During the past half century, the land utilization of Hainan Island has undergone a rapid development,but in the meanwhile, soil degradation occurs. Analysis on some basic data of the soil series collected frommore than 100 soil profiles at the end of the 1990s and beginning of this century, in combination with dataavailable, showed that soils there suffered significant decline in organic matter, experienced P and K deficiencywith soil K going on losing and undergone acidification with continuing trend. The current situation calls forstrategies to build up Hainan into an important province of sound ecology by restoring forests, to improvefood quality by implementing K supplement projects, to combat soil acidification by ameliorating the soils andgrowing leguminous crops and to ensure health of the people by developing dairy production and increasingthe daily Ca uptake by the people. | GONG ZITONG, ZHANG GANLIN, ZHAO WENJUN, ZHAO YUGUO and CHEN ZHICHENGInstitute of Soil Science, the Chinese Academy of Sciences, Nanjing 210008 (China) | 2003 | Pedosphere2003，13，1： | 9 |
| 3 | 海南岛土壤磷吸持性及其在分类中的意义显示文摘本文根据海南岛不同土壤类型的65个剖面310个土层的土壤磷(P)吸持性的测定结果,讨论土壤P吸持性与土壤类型、母岩(母质)种类、及土壤黏粒、铁铝氧化物含量之间的关系,并阐明土壤P吸持性在该地区土壤分类中的意义, 供为选用土壤分类指标参考。 | 赵文君 陈志诚 张甘霖 龚子同 | 2004 | 土壤2004，36，6： | 6 |
| 4 | Grain Size Evidence of Multiple Origins of Red Clays in the Jinhua-Quzhou Basin, South China显示文摘Six typical red clay profiles were sampled from Tangxi (TX),Langyaz (LYZ),South Shangshanwen (SSW),Xianqiao (XQ),Qijian (QJ) and Huhaitang (HHT) of Jinhua-Quzhou Basin,Zhejiang Province of China to evaluate the characteristics of grain size composition,distribution and parameters of red clays and to reveal the origin of red clays and interpret possible implications for paleoclimate in subtropical China.The results showed that red clays in TX,LYZ and SSW were fine and uniform,with no>2mm gravels and little>63μm fraction.They had a high content of 10–50μm fraction,so-called'basic dust fraction',and showed unimodal distributions,which were very comparable to those of the Xiashu Loess in southeastern China and the loess in North China.All these features reflected marked aeolian characteristics of the red clays in these areas.Red clays in XQ and QJ were much coarser than those in TX,LYZ and SSW,with high contents of >63μm fraction and even containing>2 mm gravels in some layers.The grain size distribution patterns showed significantly progressive trends from the lower profile to the upmost layer and could not be compared with those of the loess in North China or the Xiashu Loess,implying they might be derived from underlying parent rocks and had some inherited properties from bedrock.Red clays in HHT had high contents of>63μm fraction and contain many >2mm gravels in each layer.The grain size frequency curves showed multiple-peaks and some abrupt variations were also observed on the profile,revealing its alluvial or diluvial origin in HHT.The multiple origins of red clays reflected the diversity and complexity of the Quaternary environment in South China.It can be concluded that grain size is an efective proxy indicator for the origin of most deposits. | LI Jian-Wu YE Wei ZHANG Gan-Lin ZHU Li-Dong JIANG Yong-Jian GONG Zi-Tong | 2013 | Pedosphere2013，23，5： | 3 |
