| 摘 要： | 对河套灌区移植苗造林与萌蘖苗造林小美旱杨(Populus popular's)农田防护林的不同位置的风速进行了观测,并通过统计学的方法进行了比较分析.结果表明,移植苗造林与萌蘖苗造林的林带都能有效降低林网内的风速,且二者之间的防风效益无显著差异,在2H(平均树高)处风速减弱系数最大;综合考虑耗水量及营林成本,建议在该区采用移植苗造林较为适宜.

| Abstract: | Populouspopulars farmland shelterbelts were afforested by ways of planting and sprout seedling in the Hetao irrigated region. Wind speeds in different sites of shelterbelts were measured and analyzed statistically. Results showed that wind speeds were reduced effectively by Populouspopulars farmland she-lterbelts. Different afforestatio n w ays had no sig nificant difference in w ind-reducing effects. The coefficient of reducing wind was the largest in 2H. In view of w ater consumptio n and costs, afforestation by way of planting is superior to afforestation by way of sprout seedling. |
