在泰康靠山种畜场的四种类型(林粮、林药、林草和林果)草牧场中设置观测点(包括旷野处的对照点)。用综合自动气象观测仪测定气温、水汽压、相对湿度、露点、风向和风速等气象因子。以此研究草牧场防护林幼龄阶段对改善草场春季小气候的作用。结果表明,在春季树液流动初期,幼龄阶段樟子松草牧场防护林防风效能达10.68%;林网内平均气温高于旷野0.44℃,相对湿度高6.89%,蒸发量低10.33%,土壤温度和地表极温变化都比较缓和。这种风速低、气温高、湿度大的小气候条件,为牧草生长提供了良好的生态环境。
The observation points (including the control points in the wilderness) were set in the grass and pasture of the four types (forest grain, forest medicine, forest grass and fruit) of the Taikang colliery. Using integrated automatic meteorological observation instrument temperature, vapor pressure, relative humidity, dew point, wind direction and wind speed and other meteorological factors. In order to study the role of young stage of grassland pasture to improve the microclimate in spring. The results showed that in the early spring flowering season, young windbreaking effect of Pinus sylvestris var.mongolica pasture shelter was 10.68%; the average temperature in the net was 0.44 ℃ higher than the wilderness, the relative humidity was 6.89%, and the evaporation 10.33% lower, soil temperature and surface temperature changes are more moderate. This low wind speed, high temperature, humidity and microclimate conditions for the growth of forage provides a good ecological environment.
