Abstract

[Objective]In order to understand the changes of regulation function of soil moisture for the pre-harvest, post-harvest and reforestated Chinese fir (Cunninghamia lanceolata) plantation.[Method]By continuous observation in fixed locations of 24-year-old Chinese fir plantation, the soil samples before harvest, 1 year after harvest and 1 year, 3 years, 5 years, and 8 years after reforestation were collected, and the function of soil water regulation and storage capacity were investigated by laboratory data analysis.[Result]The results showed that compared with pre-harvest period, the capillary porosity of soil 1 m in depth increased by 1.70% at post-harvest period, and the non-capillary porosity decreased by 4.95%; the water holding capacity, the minimum holding capacity and capillary power of the soil increased by 4.02%, 2.67% and 5.31% respectively, but the water storage capacity declined by 14.30%; the initial infiltration capacity of the soil 0~20cm and 20~40 cm in depth decreased by 19.81% and 16.95% respectively, the stable infiltration capacity also fell by 12.97% and 14.49% respectively; during the reforestation stage, the water regulation and storage function gradually improved along with the ages of the Chinese fir plantation, for example, the initial infiltration capacity of the soil with 0~20 cm and 20~40 cm in depth at Chinese fir plantation 8 years after reforestation recovered to 62.50% and 58.83% respectively, the stable infiltration capacity also recovered to 62.22% and 48.79% compared with pre-harvest stage; If the soil before cutting with the maximum water holding capacity after cutting, minimum water holding capacity and capillary water holding capacity of 100% of the difference. with the 8-year-old stand differences before cutting only 16.90%, 17.84% and 23.20%; the soil water storage capacity returned to 33.34% of pre-harvest level. [Conclusion]The regulating function of soil moisture was weakened by harvest; however, with the reforestation activities, all the capacity of soil moisture will gradually recovered.
