| 摘 要： | 2009年7月在青藏高原主体利用英国DELTA-T公司生产的W.E.T土壤三参数仪对不同下垫面进行土壤三参数监测,共得到19组200次测量数据,对这些数据进行初步分析,结果表明:不同下垫面土壤三参数随海拔高度变化规律不同;土壤三参数之间的关系可能受到下垫面类型的影响,灌丛地土壤温度与土壤电导率的变化较一致,而含水量的变化与温度及电导率的变化没有相关趋势,草地土壤电导率与含水量有相反的变化趋势,而温度变化则与含水量及电导率变化无相关趋势。

| Abstract: | In July 2009, we monitored three vital soil properties:water content, electrical conductivity (EC) and temperature from different types of soil on Tibetan Plateau, using W.E.T Sensor produced by Delta-T company.we acquired nineteen section data which have two hundred observations.Preliminary analysis of these data showed that three vital soil properties with the same underlying surface soil have changes by elevation changed, and this change in the different types of underlying surface changes are different;the relationship between three vital soil properties may be subject to the impact of underlying surface types, the soil temperature and electrical conductivity changes in more or less uniform, while the water content changes and the changes in temperature and Electrical conductivity is not related to trends in shrub land, in grassland soil electrical conductivity and water content has the opposite trend, while the changes in temperature and water content and electrical conductivity changes are not related to the trend. |
