摘要:
采用时间序列分析法,对北京山区4种主要林分类型2010-03—10的土壤含水量与降水量之间的相关关系进行了研究。结果表明:降水序列无明显自相关性,而土壤含水量则具有高度自相关性,其中20～40 cm土层自相关性最大;降水与土壤含水量在时间上有显著的相关性,油松林地和刺槐林地受当月降水的影响最大,侧柏林地和栓皮栎林地则是受前一个月降水量的影响最大;不同土层土壤含水量与降水的相关性不同,说明不同土层受降水的影响有时间上的不同。
Abstract:
By using time series analysis, the relationships between soil moisture content and precipitation in four main mountain forests in Beijing were studied from March to October, 2010. The results showed that precipitation was not an autocorrelation series, while soil moisture content was, 20~40 cm layer was most relevant; the precipitation and soil moisture content had a significant correlation, Pinus tabulaeformis and Robinia pseudoacacia were mainly affected by current month’s precipitation, Platycladus and Quercus variabilis were mainly affected by the former month’s precipitation; different soil layers’ moisture content had different correlation with precipitation, indicating the impact of precipitation on different soil layers was also different.
