| 摘 要： | 利用北京松山地区油松树木年轮资料,按照树木年轮学要求和方法,建立年轮宽度年表.根据油松年表数值同温度与降水量等气候因子的相关分析结果,基于延庆1959-2007年的气象资料,建立生态气候指标——湿润指数和干燥度指数.选择油松差值年表数值对1959-2007年间松山地区的干燥度指数进行重建,并对1933-1958年的干燥...

| Abstract: | Tree-ring increment cores of Pinus tabulaeformis were sampled from Songshan Mountain area,located in Beijing.According to the discipline of dendrochronology,the tree-ring width chronologies were constructed.Humidity index and drought index were calculated by the correlation analysis between tree-ring width chronologies and mean temperature and precipitation,based on the meteorological data of Yanqing(1959-2007).The residual chronology was chosen to reconstruct drought index during 1959-2007,and simulate the... |
