| Abstract: | This research dealed with the general situation of the study on water consumption of vegetation in arid area,introduced five measuring methods of the water consumption,evaluated the factors affecting the water consumption,the adaptation and response of vegetation to the droughty environment,analysed the variant transpiration rate among different species,and the reaction of vegetation to the severe transpiration condition. As far as the perspective of water consumption was concerned,the eco-physical data base and ecological water consumption models should be built up,on the micro scale, molecularbiotechnology is to be applied to the research on the regulation of vegetation anti high intensity transpiration and lower water consumption in droughty regions; on the macro scale,it is need to shift the research from a single plant to plant community,ecosystem,even the global scope; and more attention is need to be payed to what will the vegetation respond to the change of global warming. |
