Differences in the various components of thermal balance and the microclimatic factorswithin lower layers of rubber tree rows between a man-made rubber-tea community(RTC)and a pure rubber garden(PRG)in the coldest month were studied in Xishuangbanna,Yun-nan province.As compared with PRG,the RTC has a soil heat release and an effective radia-tion from soil to the atmosphere reduced by 0.12 and 0.15 MJm￣(-2).d￣(-1),respectively,the netradiation and the sensible heat raised by 1.6 and 2.6 folds, respectively;mo...
