摘要：2005年7—8月在宁夏六盘山南侧的香水河小流域(半湿润地区)和北侧的叠叠沟小流域(半干旱地区),应用PV技术测定辽东栎(Quercus liaotungensis)、少脉椴(Tilia paucicostata)、白桦(Betula platyphylla)、红桦(Betula albo-sinensis)、糙皮桦(Betula utilis)、华北落叶松(Larix principis-rupprechtii)、华山松(Pinus armandii)、山杨(Populus davidi-ana)、山桃(Prunus davidiana)和沙棘(Hippophae rhamnoides)10种木本植物的多个水分参数,并对这10种木本植物的抗旱性进行综合评定。结果表明:在测定期内,用不同的水分参数比较这10种木本植物的抗旱性大小排序存在一定的差异;采用Fuzzy函数方法综合评定植物的抗旱性研究表明,香水河小流域内7种木本植物的抗旱能力由强到弱为:少脉椴、华山松、辽东栎、华北落叶松、白桦、红桦、糙皮桦;叠叠沟小流域内4种木本植物的抗旱能力由强到弱为:华北落叶松、山桃、沙棘、山杨,其与束缚水/自由水的单指标评价结果相近,说明树种的自身贮水调节能力对抗旱性评价具有重要作用。2种不同水分条件地域内华北落叶松的抗旱能力明显不同,叠叠沟小流域华北落叶松的抗旱能力比香水河小流域强,说明同一树种在干旱条件下通过长期适应会提高抗旱能力。
The water parameters of ten woody plants （ Quercus liaotungensis, Tilia paucicostata, Betula platyphylla , Betula albo-sinensis , Betula utilis , Larix principis-rupprechtii , Pinus armandii , Populus davidiana, Prunus davidiana, Hippophae rhamnoides ） were measured by pressure-volume technique, and the drought resistance of ten woody plants were evaluated from July to August in 2005 in the south （Xiangshuihe Watershed, semi-humid area） and north （Diediegou Watershed, semi-arid area） of Liupan Mountain, Ningxia. The results showed that the order of drought-resistant characteristics of the ten woody species were different evaluated by each of all water parameters in the measurement period. A comprehensive evaluation of the drought resistance of the ten plants was conducted by using fuzzy function method, and the result indicated that the ability of drought resistance of 7 woody plants in the Xiangshuihe Watershed was followed as ： Tilia paucicostata , Pinus armandii , Quercus liaotungensis , Larix principis-rupprechtii , Betula platyphylla , Betula albosinensis, Betula utilis ; the order of drought resistance of 4 woody plants in the Diediegou Watershed was followed as ： Larix principis-rupprechtii, Prunus davidiana, Hippophae rhamnoides, Populus davidiana, and the result of which was similar to that of the method by using the ratio of bound water to free water as an evaluate index. It meant that the ability of water storage in plant body played a very important role in evaluating the drought resistance of tree species. There was a significant difference in drought resistance of Larix principisrupprechtii between two different regions, the ability of drought-resistant of this tree species was stronger in Diediegou Watershed than that in Xiangshuihe Watershed. It showed that the ability of drought resistance of the same tree species could be improved as a result of long-term adoptation to drought.
