- Abstract:

The selection of suitable plants is the key point to revegetation in the reservoir riparian zone. In order to assess the feasibility and effect of the afforestation with willow along the reservoir riparian zone in the dry valley area of southwest China, a case study was conducted on the revegetated land along the riparian zone of Daqiao reservoir in Liangshan prefecture by investigating the survival rate, preserving rate, and growth performance in the different site conditions. Meanwhile, the effect of soil conservation measures was monitored by the technique of erosion pins. The results showed that:(1) willow had a higher survival rate and preserving rate in the different site conditions of the Daqiao reservoir riparian zone, which were 98% and 96%, respectively; (2) the growth performance of the willow was affected by the soil conditions, which ranked brown soil, yellow-brown soil, and red soil; (3) the growth performance of willow decreased with the increase of submerge depth, and the willow had best growth in the area inundated less than 5 meters; (4) stone barricade was more suitable for the steep slope with more than 15 degrees. It prevented the soil loss from the planting hole, and had an erosion reduction efficiency of 75%.
