  leaf temperature
When soil water is sufficient, the main factors affecting Tr were relative humidity (RH), air temperature (Ta) and leaf temperature (Tl) in July, August and October respectively.
      
The registered indices comprised leaf temperature, leaf transpiration conductivity, and the average daily increment of the leaf area.
      
The drought duration did not affect the adaptation of leaf water balance, it was determined only by leaf temperature and water supply.
      
The authors conclude that water supply and leaf temperature determine plant resistance to soil drought.
      
Measurements of leaf temperature and the vapour pressure gradient between the leaf and the air indicated that leaf surface water originates from the plant.

Maowusu sandland is classical one of arid and semi\|arid sandland in China.Water is the most limited factor there.The distribution pattern and productivity of terrestrial ecosystem are greatly affected with the future global severer change,especially global precipitation change.It is investigated for the response of physiological ecology of A.ordosica seedlings,a dominant shrub in Maowusu sandland,to the global precipitation change by artificially controlling four water supply gradients.The results show that the diurnal changes of photosynthetic rate,transpiration rate,stomatal conductance,intercellular CO 2 concentration,leaf temperature,solar energy utilization efficiency,and water utilization efficiency of A.ordosica seedlings show significantly different under different water supply treatments.The seedlings have low stomatal conductance and transpiration rate by shutting stomata so as to lower losing water by transpiration,mainly due to severe water stress in the deficit water supply,but high stomatal conductance,intercellular CO 2 concentration,transpiration rate and low leaf temperature by opening stomata so as to increase photosynthesis in full water supply.So the seedlings show different physiological ecological adaptation strategies under different water supply.The fluorescence efficienc increases with the increase of water supply,which explains on mechanism why photosynthesis increases with the increase of water supply treatments.The analyses of backward eliminated variable indicate that the number of main factors which restrict photosynthetic rate of seedlings decrease with the increase of water supply.PAR and leaf temperature are most restricted factor in full water supply,and transpiration rate,intercellular/air CO 2 concentration margin and PAR in middle water supply,but transpiration rate,stomatal conductance,intercellular/air CO 2 concentration margin,leaf/air temperature and air temperature in deficient water supply.

WT5BZ]Maowusu sandland is a typical dry and semi dry sandland in China.Water is the most important limited factor there.It is greatly affected for distribution pattern of terrestrial ecosystem and natural environment with great global change,especially global precipiatation change.The response of transpiration is investigated for seedlings of S.psammophylla , a dominant shrub in Maowusu sandland,to the global precipitation change by artificially controlling four water supply levels of 157.5 mm、315 mm、472.5 mm and 630 mm.The results show that evapotranspiration of S.psammophylla seeding increased with the increase in water supply in Maowusu sandland.The average daily evapotranspirations for four levels of water supply were 1.63 mm、3.11 mm、4.37 mm and 5.66 mm,respectively.And the evaporation contributed the main part in evapotranspiration.Transpiration rate of the seedlings showed strongly midday depression under low water supply,but not under full water supply.Correlation analysis showed that meteorological variables,such as containing water rate of sandland,photosynthetic available radiation,air temperature,saturated water vapour pressure difference,and physiological variables,such as leaf area index,leaf temperature,stomatal conductance,affected transpiration of S.psammophylla seedlings .
