四姑娘山国家级自然保护区岷江冷杉枯落物及土壤的持水能力研究

Study of Water Conservation Capacity of Mingjiang Fir Litter and Soil of Siguniang Mountains National Natural Reserve

通过对四姑娘山国家级自然保护区岷江冷杉林地表土壤和林下枯落物的实验分析,得出四姑娘山自然保护区岷江冷杉林0～40cm深度的土壤层最大贮水量为1694.8 t/hm2,林下枯落物最大持水量为233 t/hm2。四姑娘山自然保护区岷江冷杉林土壤及枯落物持水的最大值为1927.8 t/hm2。

The experiment of fir Litter and surface Soil of Mingjiang fir forest of Siguniang Mountains National Natural Reserve show that the Maximum water source conservation capacity is 1694. 8 t/hm^2 from 0 to 40cm depth of soil layer. The maximum water source eor/servation capacity of forest litter is 233 t/hm^2. The Maximum water source conservation capacity of fir litter and surface Soil of Mingjiang fir forest of Siguniang Mountains National Natural Reserve is 1927. 8 t/hm^2.
