Study on the Dynamic Changes of Soil Moisture in Pinus Tabulaeformis Plantation in Shilou County of Shanxi Province
The effects of slope orientation,slope position and afforestation density on soil moisture were studied by measur-ing soil moisture content at different soil depths in the Pinus tabulaeformis plantation in Shilou County of Shanxi Province.The results showed that there was no significant difference in soil moisture content among different slopes of Pinus tabulae-formis plantations,with the order from high to low being the north slope>the northwest slope>the east slope.There was a significant difference in soil moisture content among different slope positions,with the order from high to low being down-side slope position>middle slope position>upside slope position.There was a significant difference in soil moisture con-tent among different afforestation densities,with the order from high to low being 1 465 plants/hm2>968 plants/hm2>2 193 plants/hm2.There was no significant difference in soil moisture content under different soil depths,and the soil moisture content decreased with the increase of soil depth.
