【摘要】 通过研究水湿地兴安落叶松蒸腾速率在时间和树冠空间上的变化以及环境、树龄等对其的影响，估出水湿地兴安落叶松的蒸腾耗水量，从而为研究水湿地生态环境的变化及其改造利用所采用的工程和生物措施提供一定的理论依据。更多还原

【Abstract】 The author has measured the change of the transpiration in the wake of time,the positions of the canopies,the age and the habitat of Larix gmelinii.The evapotranspi-ration for the plantation has been estimated for providing theoretical basis for research on thevariations of ecological environments and the engineering and biological measures for thetransformation and utilization of marshland.更多还原
