中文摘要	利用2006--2009年新疆奇台县沙漠前沿人工植被恢复区和天然植被恢复区监测到的风的相关数据,研究了不同时间尺度上天然和人工植被恢复模式对风的影响差异.结果表明:在年度尺度上,人工植被恢复区的无风天比天然植被恢复区多58.8d/a,年均降低风速0.88m/s,多消抵65.2%的风动能,人工植被恢复对北向和西北向风的消抵作用最显著,对西南向风的消抵作用最弱;在月尺度上,每年4月份至6月份月均风速最大,人工植被恢复区的消抵作用明显,平均风速比天然植被区低1.29 m/s,而12月份至次年2月份月均风速最小,人工植被恢复区的消抵作用减弱,平均风速仅比天然植被恢复区低0.58 m/s,每时段(4--5月份,6--9月份,10--11月份1,2--3月份)人工植被恢复区可消抵风速40%以上和风动能70%以上;在昼夜尺度上,奇台县沙漠前沿最大风速基本出现在16:00--19:00时段,不同植被恢复模式下,4--5月份每天风速较大时段持续时间稍长,且风速昼夜间变换较之10--11月份1,2--3月份剧烈
英文摘要	A survey was conducted to study the differences in wind velocity,direction,and kinetic energy measured on multiple time scales in natural and planted vegetation restoration areas in the desert of Qitai County,Xinjiang Uygur Autonomous Region during 2006-2009.On an annual scale,there were 58.8 more calm days per year in the planted vegetation restoration area than in the natural vegetation restoration area.Compared with the natural restoration area,average wind velocity and wind’s kinetic energy in the planted restoration area reduced by 0.88m/s and 65.2%,respectively.The planted area showed the greatest capacity to reduce winds from the north and northwest,and the weakest capacity to reduce winds from the southwest.On a monthly scale,average wind velocity in the planted restoration area decreased by 1.29m/s during April and June and 0.58m/s during December and February.Average wind velocity and kinetic energy in the planted restoration area over four seasons lowered by 40% and 70%,respectively.On a daily time scale,the highest wind velocity usually occurred from 16:00-19:00 and the duration was longer in spring and summer than in autumn and winter.The change in wind velocity under the two vegetation restoration modes was more violent in spring and summer than in autumn and winter
