| 摘 要： | 以黑龙江省西部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、落叶松和小黑杨纯林,小黑杨和樟子松混交林,小黑杨和落叶松混交林中的各树种蒸腾速率进行了比较研究.结果表明:(1)与小黑杨混交的樟子松和樟子松纯林蒸腾速率日变化差别不大,蒸腾速率的月变化差异最小,各结构防护林树种的蒸腾速率均呈现抛物线变化趋势.(2)与小黑杨混交的落叶松在整个生长季的月平均蒸腾速率为落叶松纯林的76.96%,与落叶松混交的小黑杨的蒸腾速率比小黑杨纯林低17.43%,小黑杨与落叶松混交林能够有效地降低这两个树种的蒸腾速率.(3)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.
