摘要

以黑龙江省西部半干旱地区主要农田防护林树种为研究对象

采用快速称重法对樟子松、落叶松、小黑杨和银中杨的蒸腾速率进行了研究。结果表明

各树种月蒸腾速率的变化不同

樟子松的蒸腾速率始终最小。樟子松蒸腾速率的月变化差异最小

各防护林树种的蒸腾速率均呈现抛物线变化趋势。农田防护林在多种环境因子的综合作用下

其蒸腾速率受大气温度和太阳总辐射的影响较大

并且蒸腾速率与大气温度、太阳总辐射和土壤水含量均表现出正相关

与相对湿度和风速均表现出负相关。

Abstract

The transpiration rates of Pinus sylvestris L.var.mongolica Litv.

L arix gmelinii

Populussimonii×P.nigra

and Populus alba× P.berolinensis

the main tree species of farmland shelterbelts in the semi-arid region in the wesTheilongjiang Province of China

were studied by using the method of rapid weighting.Results showed that the monthly variations of the transpiration rates were different and the transpiration rate of Pinus sylvestris L.var.mongolica Litv.was the slowest.The monthly variation of the transpiration rate of Pinus sylvestris L.var.mongolica Litv.was the least and the transpiration rates of other structures showed a parabolic trend.The transpiration rate of farmland protection forest was seriously affected by atmospheric temperature and solar radiation in a variety of environmental factors in combination

and the transpiration rate showed the positive correlations with atmospheric temperature

solar radiation

and soil water content

but the negative correlations with relative humidity and wind speed.
