- The basic size composition of communities were revealed by these spectra . these spectra among stations and these 2 ecosystems showed minus difference caused of water depth or seasonal change
Sheldon型粒径谱的esd为500 m或者生物量粒径谱的粒级单位为2时,图形出现波谷。 - Sample ' s analyses and tests in laboratory , this thesis makes a detailed research on holocene deposits characteristics of mu us desert , especially on characteristics of grain size composition , which break through previous description of determining the nature and gain a series of number indexes . at the same time , this thesis has also researched arenaceous source on every part of mu us . firstly mu us desert ' s forming process is deeply influenced by the east asian monsoon , the grain size gradually becomes smaller , while the magnetic susceptibility becomes larger from northwest to southeast this phenomenon not only appears on the surface of mu us , but also obviously reflects on the same layer of different places
根据大量野外详细考察和室内样品分析与测试,本文对毛乌素沙地全新世地层沉积特征做了细致的探讨,尤其对区域地层的粒度组成特征做了进一步的研究,突破了以往的定性描述,得出了一系列量化指标;结合野外的考察工作,对其不同地区的沙质来源做了详细分析,主要得出以下结论: 1 、毛乌素沙地形成过程深受东亚季风影响,粒度自西北向东南逐渐变细、磁化率值逐渐变大。 - 2 . by the analysis of grain - size accumulative centigrade content , grain - size composition and grain - size parameters performed on samples in baijiaziu profile and mafangtan profile , nine stages of hydrological and climatic changes since the last 1300 years have been distinguished . the first , the third , the fifth , the seventh and the ninth layers of the stratigraphical sequence are finer while the second , the fourth , the sixth and the eighth are coarser
据此,将白家嘴剖面划分为9个地层单位, 4个沉积旋回,其中剖面1 、 3 、 5 、 7 、 9层较细, 2 、 4 、 6 、 8层较粗,并认为此沉积序列表明近1 . 3ka以来渭河古水文与古气候大致经历了9个变化阶段。 - Under the direction of chinese soil taxonomy , part purple soils developed on the purplish standstones of j2 # j3 in sichuan basin were systematically studiedaccording to natural landscape , profile modality and quick - test , applying to methods statistic analysis and system integration , main affecting factors , indexs of soil series taxonomy and retrieval orders were systematically discussed . the results showed : 1 ) organic substance , total nityogen , total phosphate , total potassium and particle size composition were distinctly related with many soil characters . organic substance , calcium carbonate , available phosphate # size composition were much different in all swatches . besides , soil structure and the depth had profound affection to it . 2 ) affecting factors : soil structure , texture style and organic substance phosphorous
本文以土壤系统分类理论为指导,以四川盆地侏罗系蓬莱镇组、沙溪庙组和遂宁组紫色岩上发育形成的部分紫色土为研究对象,利用spss统计软件相关功能,结合供试土壤的自然景观、剖面形态和室内测定的理化性质,对土系分化的影响因子、土系划分指标和检索顺序进行了系统的探讨,结论如下: ( 1 ) 、供试紫色土中有机质、全氮、全磷、全钾和颗粒组成与多个土壤性质均呈显著或极显著相关;有机质、碳酸钙、有效磷、颗粒组成等性质在供试土壤方差分析中变异系数均较大;土体构型及土体的深度对土壤性质也有深刻影响。
