中文摘要:对2015年所采集的0~20cm、20~40cm土壤水样品和对应的土壤样品进行了测试分析,运用灰度关联和典范对应分析的方法研究了岩溶峰丛山区土壤水的地球化学特征及其与土壤环境条件的关系。结果表明:岩溶峰丛山区土壤水地球化学性质及其对应的土壤环境指标均存在不同程度的空间异质性,其中土壤水和土壤中的pH值变异系数在2.48%~10.44%,变异最小;除了镁离子和氯离子,土壤水的其他地球化学指标的变异系数均表现为0~20cm大于20~40cm,20~40cm土壤水地球化学性质更为稳定。土壤水的HCO-3、Ca2+、SO2-4浓度是影响土壤水地球化学特征的主要因子,且HCO-3起到主导作用。典范对应分析结果显示,不同的土壤水地球化学性质与土壤环境因子关联性差异明显,影响土壤水地球化学特征的主要土壤环境因子中的全钾含量、交换性镁含量、有效锌含量、0.2~2.0mm粒径和0.002~0.020mm粒径的土壤颗粒等因子对土壤水中的Mg2+浓度、HCO-3浓度、pH值影响较大,有效铜含量、胡敏酸含量、胡敏素含量主要影响土壤水中Na+浓度、K+浓度,而速效钾含量、土壤含水率、小于0.002mm粒径机械组成等土壤因子则主要是通过Na+浓度、K+浓度、Cl-浓度、SO2-4浓度等指标影响土壤水的地球化学特征。

Abstract:The objective was to clarify the characteristics of soil water geochemistry and the relationships between soil water and soil environmental factors in karst peak-cluster area. Soil water samples and soil samples were collected from the depths of 0~20cm and 20~40cm in each sampling site. And all samples were tested to meet groundwater testing standards and soil testing standards respectively. The methods of grey relational analysis (GRA) and canonical correspondence analysis (CCA) were employed to reveal the characteristics of soil water geochemistry and the relationships between soil water and soil environmental factors. The results revealed that geochemical properties of soil water and its corresponding geochemical indicators of soil were with different levels of spatial heterogeneity. And the variable coefficient of pH value was the smallest among the indicators, just ranging from 2.48% to 10.44%. Except Mg2+ and Cl-, the variation coefficients of soil water geochemistry were decreased with the increase of depth. The properties of soil water geochemistry in the depth of 20~40cm were more stable than that of 0~20cm. HCO-3, Ca2+ and SO2-4 were the main factors affecting the soil water geochemical characteristics, with HCO-3 as a leading role. Furthermore, the CCA results showed that the correlations between geochemical properties of soil water and soil environmental factors were different. Among the main soil environment factors influencing soil water geochemistry, the total potassium (TK), exchangeable magnesium (EMg), available zinc (AZn) and soil particles of 0.2~2mm and 0.002~0.02mm diameters influenced the Mg2+, HCO-3 and pH value of soil water;the available copper (ACu), humic acid (HA) and humin (HM) mainly impacted Na+ and K+ of soil water;rapidly available potassium (AK), soil water content and soil composed of particles of diameter less than 0.002mm, and influenced soil water geochemistry by Na+, K+, Cl-, SO2-4 and so on.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
