估计和评价植被蒸散耗水时，用叶面积指数或叶生长量指标可能比密度更符合生物学逻辑。
The LAI and leaves biomass may be better indicators than density for estimating and evaluating water consumption of vegetation, since it is more biological based.
用它计算的水面最大可能蒸发量乘以一定系数，便可换算成农田蒸散量。
The amount of evapotranspiration of farm land can be calculated by multiplying the largest possible evaporation capacity of water surface with a special coefficient.
蒸散速率与地下水位变化成反相关关系，地下水位的大幅度下降可能致使柽柳死亡。
The variation of evapotranspiration rate has negative relation with water table change, and if the water table lowers greatly Tamarix will die from moisture shortage.
