In order to compare the phenological characteristics among mesophyte,xerophyte,and psammophyte,nine phenological phases of 48 typical plant species in Minqin Desert Area were observed for 20 years(1985—2004).
研究结果表明:从中生植物到旱生植物再到沙地旱(中)生植物,同一物候期的多年变幅增大;从旱生植物到沙生植物的物候期的多年变幅大于从中生植物到旱生植物的多年变幅;不同植物的物候期差异主要表现为从花蕾花序期开始到果实脱落末期的各个物候期,从中生植物到旱生植物再到沙地旱(中)生植物,这些物候期表现出逐渐延迟的趋势;当地冬季漫长,夏季持续日数较长,秋季最短,春季和秋季物候频数分布较多,植物活动日数相对较短;运用聚类分析方法研究包括中生植物、旱生植物和沙地旱(中)生植物的物候特征,能更好的从不同植物类型来揭示植物物候特征。
