摘要
木本植物物候特性在研究植物群落演替、生态系统物质循环及气候变化等方面具有重要意义。以且末地区杏树、银白杨、白柳、桑树和葡萄5种木本植物物候为研究对象,采用趋势分析、显著性检验、Mann-Kendall突变检测等方法,分析植物物候变化特性及其与气温的关系。结果表明:(1)物候期的变化特征为:杏树、银白杨、白柳、桑树和葡萄的展叶始期、始花期提前,叶色全变期推后,末花期、落叶末期各不相同。杏树、桑树和葡萄的生长季延长,银白杨、白柳略微缩短。(2)杏树、桑树和葡萄的物候特征变化较为显著,银白杨、白柳不显著。(3)植物物候变化的总趋势为:春季物候提前,秋季物候推后,生长季延长,与气温的变化趋势一致。
The paper aims to study the importance of plant community succession, ecosystem material cycle and climate change. We analyzed the phenological characteristics and its relationship with temperature of 5 woody plants including apricot tree, white poplar, white willow, mulberry tree and grape tree in Qiemo from1981 to 2014 by using methods such as trend analysis, significance test and Mann-Kendall mutation test. The results showed that:(1) the phenological changes were characterized as: the leaf expansion and the beginning of flowering of apricot tree, white poplar, white willow, mulberry tree and grape tree were ahead of time, the leaf color change period was postponed, the end of flowering and the end of the leaves were different;the growing season of apricot, mulberry and grape tree were prolonged, that of white poplar and white willow were shortened slightly;(2) the phenological characteristics of apricot, mulberry and grape tree were significant, but that of white poplar and whitewillow were not significant;(3) the general trend of plant phenological changes was: the phenology in spring was in advance, the phenology in autumn was prolonged, the growing season was extended,and the plant phenological changes were consistent with the trend of temperature changes.
