- Abstract:
- In vulnerable area of arid and semiarid northern Shanxi organism’s habits, study on soil and water conservation and ecological restoration was carried out in Zhangjiashan Valley of Ningwu County. Multi-directionally qualitative and quantitative impact to vegetation restoration by artificial measures to promote was discussed. The trial native trees were chosen as the added source of trees. Replanting density was determined according to the wind-borne species scope of the spread. The mixed mode was figured out based on local condition. The integrated technology such as large bags of nutrition field planting was used to improve the survival rate of afforestation. After 5 year test, the survival rate of planted trees has been up to 90%～95%, and the reserved rate has been up to 80%～85%. The vegetation coverage of experimental zone has been up to 72.2%, the growth of average annual has been up to 8.3%, the new increased coverage of man-added sources has been up to 10.6%, the new increased biological production has been up to 33.72%. Vegetation community has been gradually evolved which species distribution was uniform and the structure was scattered.
