China); Yao Xianming(Office of Forest Rehabilitation of Chaoyang County); Liu Baoshu(Forestry Bureau of Chaoyang County); Zhang Fengxia(Forest Prevention Station of Chaoyang County); Lan Xianzhen(the Government of Taizi Village, Chaoyang County)Large numbers of experiments indicate that DJS afforestation is very effective in saving water and preserving soil moisture in semi-arid areas. 19 576～37 330 kg water and 1 756.9～1 977.7 Yuan of silvicultural cost could be saved on per hectare, and the economic benefit reached 783～896 Yuan per hactare. The survival rate and preservation rate of seedlings were improved, and the project of abandoning farmland to forest restoration was accelerated. Therefore the silvicultural quality is assuring when adopting DJS afforestation technique.
