Impact of time lags on diurnal estimates of canopy transpiration and canopy conductance from sap-flow measurements of Populus cathayana in the Qinghai–Tibetan Plateau被引量：3
《Journal of Forestry Research》2017年第3期481-490,共10页Hui Wang Kangning He Runjie Li Zhuping Sheng Yun Tian Jun Wen Bo Chang 
supported by the Qinghai province natural science foundation project(2015-ZJ-902);the Qinghai province science and technology plan program(2014-NK-A4-4)
Recently, canopy transpiration （Ec） has been often estimated by xylem sap-flow measurements. However, there is a significant time lag between sap flow measured at the base of the stem and canopy transpiration due to...

RELATIONSHIP BETWEEN CANOPY TEMPERATURE AND SOIL MOISTURE
《Chinese Science Bulletin》1987年第17期1208-1212,共5页董振国 
I. INTRODUCTION The canopy temperature is decided by heat and vapor flux in SPAC. During the day, transpiration is the main mode of consuming excess heat in watered fields. When the soil moisture is not adequate to me...
