摘要
对广东省东莞市大岭山森林公园开展了森林小气候的调查,结果表明:大岭山森林公园的环境状况达到了二级标准水平;有林地与空旷地相比,其土壤温度、空气温度的日变化相对平缓,有林地的土壤温度以阔叶成林的最低,幼林的次之。有林地的空气负离子含量明显比空旷地的高,空气中可吸入粉尘质量浓度、空气粒子数均比空旷地的低。大岭山森林公园可作为休憩、娱乐和保健的场所。
The forestry Microclimate Effectiveness in Pearl river Delta are studied in the paper. The results show ： （ 1 ） the forest land in Dong Guan, Da Ling Shan forest Park,the daily change of the soil temperature and air temperature was relatively slow , and PMIO and particle of air was low but anion content in the air was high , that was opposite to the hollowness; （2）In Dong Guan,Da Ling Shan Forest Park, the air environment reach the second class standard, and it was siteable for resting, entertainment and sanitarian.
