摘要
以甘肃省渭源县一林区为研究对象,对云杉林、油松林、杨树林、混交林4种不同植被恢复类型的林地和荒草地进行了小气候环境的监测研究,结果表明:土壤温度以荒草地的年变化幅度最大,4种林地的年变化幅度较小且差异不大,深层土壤的温度变化比浅层土壤更为稳定;荒草地的环境温度最高、环境湿度最低,混交林的环境温度最低、环境湿度最高;植被覆盖可以在一定程度上降低环境温度,提升环境湿度,阔叶林比针叶林更能够增加环境的湿度。
Taking a forest region in Weiyuan County of Gansu Province as the research object,the microclimate of four different vegetation restoration types of Picea asperata forest,Pinus tabulaeformis forest,poplar forest and mixed forest of forest land and waste grassland was monitored and studied.The outcomes show that a)the annual variation range of soil temperature is the largest in waste grassland,the annual change range of the four kinds of forest land is small and the difference is not big and the temperature change of deep soil is more stable than that of shallow soil;b)the environmental temperature of the waste grassland is the highest and the environmental humidity is the lowest.The environmental temperature of the mixed forest is the lowest and the environmental humidity is the highest and;c)vegetation cover can reduce the environmental temperature and improve the humidity to a certain extent.Broad leaved forest can increase environmental humidity more than that coniferous forest.
