摘要
在影响植物生命活动的各种生态因子中,水分是主要限制因子。与植物水分生命表征直接相联系的蒸腾强度、蒸腾量、蒸腾耗水变化规律及其与环境因子的关系。蒸散发既包括从地表和植物表面的水分蒸发,也包括通过植物表面和植物体内的水分蒸散。指出目前蒸散耗水量的计算方法大致可以分为:微气象学法、植物生理学法、以及SPAC综合模拟法等。并指出植被蒸散是一个复杂的物理过程和生物过程,是未来研究蒸散的主要途径和方向。
In each ecology factor of effecting the plants vital movement. The water is the main factor. The direct connection to the plant water＇s life attribute is the transpiration intensity,the transpiration quantity,the change rule of the transpiration and its relationship with the environment factor. The transpiration includes the water from the ground and the plant surface, also the inside of the plant. It points out that the measurement of the transpiration at present contains micrometeorology,photobiology and SPAC synthesis analogue. And it also points out that plants transpiration is a complex physical process and organism process, and is the main path and the direction of the future study in the transpiration.
