| 摘 要： | 通过对东沙窝沙漠区采取提前整地、压沙等方式,选用良种壮苗、蘸泥浆、覆沙、平茬复壮、纯林改混交林等综合技术进行造林试验,结果表明,试验区造林成活率、保存率普遍提高,小气候环境明显改善:植被区风速比旷野区降低了25.8%～32.6%;灌木固沙林在夏季降低气温10℃左右,降低地温6～10℃,冬季地面最高温度提高2～4℃。

| Abstract: | Mixed silvicultural techniques(site preparation in advance,covering sand,selected strong sprout seeds,dipped in mud,sand-covered,stubble rejuvenation,transforming the pure forest into the mixed forest) were adoptted to conduct afforestation experiments in Dongshawo desert area.Result shows that survival & preservation rate of afforestation in test area generally increase,and the micro-climate environment improved significantly:wind speed of vegetation decrease by 25.8%-32.6% than that of the wilderness area;shrubs sand-fixation forest decrease the temperature of 10℃ in summer and decrease ground temperature of 6-10 ℃;the highest ground-temperature increase by 2-4℃ in winter. |
