Juglans regia is an important economic tree *** of its stock sap flow was carried by SF100 heat pulse recorder in dry season(April-July) in area of conversion farmland for forest and surrounding meteorological factors such as air temperature,air relative humidity and radiation intensity were monitored *** plot locates in Pingshan,*** study would offer some references for vegetation *** results showed that the Juglans regia stock sap flow changed obviously between day and night,which followed a single peak type *** amplitude was big in sunny day and little in cloudy day;In April-May,sap flow was big and little in June-July because of soil water stress;Influencing order on stock sap flow flux by meteorological factors was sun radiation>air temperature>relative humidity respectively.
