【摘要】 本文以巴林右旗科尔沁沙地2年生杨柴(Hedysarum laeve)沙障为研究对象,对营建沙障迎风坡,不同坡位主要气象因子的日变化进程测定和分析,结果表明:杨柴沙障对沙地小气候的影响主要表现为风速和气温降低、空气相对湿度增加;不同坡位沙障的影响不同,位于迎风坡中部的杨柴沙障对沙地小气候的改善作用较明显。更多还原

【Abstract】 The two years old plants Hedysarum laeve which is growing on the keerqin sand ground in Balinyouqi was taken as the studying object,through observing and analyzing the diurnal patterns of the main meteorological factors in the different height of the weather hills with sand barriers were observed and analyzed,the result showed that the main effects of the Hedysarum laeve sand barriers to the microclimate of the sand ground is the drop of the wind speed and the air temperature,the increase of the relative air humidity;also the sand barriers in the different height have the different influence,the function of the sand barriers in the middle height of the weather hill to the microclimate of the sand ground was more obvious.更多还原
