Abstract:
Soil physical properties are the important indicators for measuring soil quality.The soil water-physical properties were tested in the spruce plantation,shrubs,economic forests and agricultural land in Lixian,located in the upstream areas of the Minjiang River.The results showed that (1) The soil bulk density of the spruce plantation was the lowest,soil capillary porosity,non-capillary porosity,maximum water holding capacity,and capillary water holding capacity were significantly higher than those in other three vegetation types.(2) The non-capillary porosity,capillary water holding capacity and maximum water holding capacity of the shrub forest and economic forest were not significantly different,but the soil bulk density of shrub forest was significantly lower than that of economic forest.(3) The soil bulk density of the agricultural land was significantly higher than that of the other three vegetation types.The non-capillary porosity,capillary water holding capacity,and maximum water holding capacity of the agricultural land were significantly lower than those in other three vegetation types.It could be seen that there were large differences in the soil physical properties of the four vegetation types.It would play an important role to choose a reasonable vegetation type and reduce human disturbance in vegetation restoration and ecological function improvement in the upstream areas of the Minjiang River.
