- Abstract:
- Changes of soil water content in different layers, including 0—20 cm, 20—50 cm and 50—80 cm under Phyllostachys pubescens forest were investigated in Mao’ershan Mountain in upper reaches of Lijiang River. The results showed that: (1) there were significant differences for soil water contents in three layers (p < 0.01) and annual average values were 39.49%, 41.17% and 44.15%, respectively, soil water content in 0—20 cm was the lowest, and increased in other two layers, significant relationships between precipitation and soil water content in three soil layers were also found; (2) soil water content changed synchronously with rainfall and there were always platform stage, rising stage, peak value stage and decreasing stage in the process, response of soil water content to rainfall was comparatively complicated; (3) at the rising stage, soil water content in 0—20 cm layer increased at the fastest rate and soil water in 50—80 cm layer declined quickly at decreasing stage which was related with initial soil water content and intensity of rainfall. This study would provide scientific basis for better understanding of the relationships between forest vegetation and its hydrological effects, helping to facilitate water resources and achieving wise forest management in upper reaches of Lijiang River.
