中文摘要根据贡嘎山东3000m处观测实验站记录资料,分析土壤水分含量动态变化,初步结论如下:裸地土壤含水量在高于次生林地且变化幅度大;土壤上层水分含量比下层低且变化幅度大;土壤水分含量动态变化与降水、蒸发关系不很密切;除11月中下旬至次年4月上旬为冻结期外,5~10月土壤水分含量变化可大致划分以下三个阶段:融冻上升期、水分充足稳定期、水分含量下降期。
英文摘要Based on the observed data at the height of 3000?m on east slope of Gongga Mountain,soil water content dynamics was studied in this paper.The results showed that the soil water content of slash was higher and varied more widely than those of secondary forest, and the soil water content of surface layer was less and varied more widely than those of subsurface layer.The soil water content dynamic did not correlate significantly with precipitation and evaporation.Except the freezing period from November to April of the next year,the seasonal variation of soil water content could be divided into three periods: melting and rising period,stabilization period and lessening period.
