Abstract:The soil sample survey and indoor soaking method were used to study the hydrological effects of six different stand types in Huluyu Forest Farm, Hongya mountain nature reserve, Yixian County, Hebei Province. The results showed that the accumulations of litter in 6 stand types ranged from 5.25 to 15.70 t/hm2, and the accumulations were the largest in broad-leaved robinia pseudoacacia, followed by mixed needle-width forest, and the smallest in coniferous forest. The total volume of semi-decomposed layer of each forest was larger than that of non-decomposed layer (the non-decomposed layer of pure Pinus tabulaeformis, Diospyros Iotus and Pinus tabulaeformis mixed forest was larger than that of semi-decomposed layer). The maximum water capacity range was 10.55~25.04 t/hm2, among which Quercus variabilis (25.04 t/hm2) was the largest, Robinia pseudoacacia (23.66 t/hm2) was the second largest, and Pinus tabuliformis (10.55 t/hm2) was the smallest. The range of maximum water holding rate was 171.19%~260.20%, among which Pinus tabulaeformis of coniferous forest was the largest and Platycladus orientalis was the smallest. The range of effective storage was 6.25~17.60 t/hm2, among which Quercus variabilis (17.60 t/hm2) was the largest in broad-leaved forest, Robinia pseudoacacia (17.30 t/hm2) was the second largest, Platycladus orientalis (6.25 t/hm2) was the smallest. The effective retention rates were slightly different. The coniferous Pinus tabuliformis forest was the largest with the value of 180.29%, followed by the broad-leaved Quercus variabilis forest (162.98%), the needle and broad mixed forest Diospyros Iotus and Pinus tabulaeformis was the smallest with the value of 77.22%.The comprehensive analysis showed that the water holding capacity of the litter layer of Quercus variabilis and robinia pseudoacacia was better than those of the litter layer of other four stand types.
