Abstract: In this paper, with Populus in windbreaks/shelterbelts as study plants in three regions such as plain region of northern part of Liaoning, ecoton region of Bashang, Hebei Province, and semiarid tableland region of Weibei, Shanxi Province, and based on the main natural disaster factors and protection objective in these three regions, the data investigated in the study area were analyzed through statistics methods. The optimization management parameters were put forward for the sustainable and intensive management model of windbreaks/shelterbelts in three regions. The optimization porosity of shelterbelts/windbreaks in northern part of Liaoning, Bashang and Weibei should be 0.25~0.35,0.20~0.30, and 0.275~0.375 respectively. The distance between main belts should be 450~500m, 200m, and 200~250m respectively, and the distance between lateral belts should be 500~1000m, 500m, and 350~450m. The belt width should be 8m, 9m, and 4.5~8m respectively, with 3~4, 6, and 2~4 rows respectively. The spacing of trees should be 2m×1.5~3m, 1.5m×1.5m, and 1.5~3m×1.5~3m respectively. The protection mature age should be 15~16yr, 14~15yr and 12~14yr respectively. The protection mature time should be 10yr. 10~11yr. and 12~14yr respectively. The regeneration mode should be alternate strip-felling model, half strip-felling and engrafting model, and alternate strip-felling model respectively.
