The Effect of in-forest raising of Sika Deer on the Physical and Chemical Properties of Forest Soil
In this study,we determined the effects and degree of disturbance of sika deer farming on the physico-chemical properties of forest soil by determining the physico-chemical indices such as soil bulk density,total porosity,water content,total nitrogen,total phosphorus,available phosphorus,and available potassium of sika deer farmed forest soils and explored the response of the soils to the disturbance of sika deer farmed forest soils.It was found that with the increase of understorey breeding density of sika deer,the soil bulk density of the forest floor increased,the porosity decreased,the water content decreased,and the content of total nitrogen,total phosphorus,available phosphorus,and available potassium in the soil showed the phenomenon of first increasing and then decreasing.Changes in the physico-chemical properties of understorey soils in the area of sika deer farming are influenced by sika deer farming and their density,and moderate stocking favours the improvement of soil physical properties and increases the deposition of soil nutrients.Once the stocking density exceeds the carrying capacity,it will result in the deterioration of the physical properties of the soil as well as the loss of nutrients.
