Methods for sampling and analysis of water isotopes as follows were developed for water cycle research ;(1) Sampling device for an aircraft observation(2) Sampling device for a tethered balloon observation(3) Sampling device for tower observation(4) Analysis line for atmospheric water vapor(5) Soil and plant water extraction lineDeveloped methods were applied for the atmospheric water vapor and soil and plant water samples obtained in Eastern Siberia in 1999 to 2001. Oxygen and hydrogen isotope ratios of extracted water from soil and plant samples were successfully used for tracing water. Isotope data indicated that water movement in the soil depended on the moisture condition. Isotope dataset on the atmospheric water vapor also can be used for analysis of recycling of water in the region.

(1)飞机观测采样装置(2)系留气球观测采样装置(3)塔式观测采样装置(4)大气水汽分析线(5)土壤和植物水提取线对1999~2001年在东西伯利亚采集的大气水汽和土壤及植物水样进行了研究。从土壤和植物样品中提取的水的氢、氧同位素比值被成功地用于示踪水分。同位素数据表明，水分在土壤中的运移取决于水分条件。关于大气水汽的同位素数据集也可用于分析该区域的水循环。
