| 摘 要： | 对半干旱地区疏林式草牧场防护林的气象效应进行了研究。结果表明，与无防护林庇护的草场相比，疏林式草牧场防护林具有显著改善草场气象因子的效应。其防护效应随观测高度的增加而减弱。此外，疏林式草牧场防护林还可以调节林内的地表温度，降低林内的蒸发量。

| Abstract: | In the paper; the meteorological effects of protective plantation of sparse woods on grassland and pastureland in the semi-arid windy and sandy area were studied. Compared with the open area. protective Plantation of sparse woods has obvious meteorological effects, and its protective effects reduce as the observed height in sparse woods is raised. In addition, ground temperature is adjusted and ground evaporation is reduced in sparse woods. |
