河北坝上杨树人工林径向生长与气候因子关系数据集

Climate Effect on the Radial Growth of Populus Simonii Dataset in Bashang Area of Hebei Province of China

作者在河北省坝上地区波罗素林场(41°03’N-41°27’N,114°20’E-115°58’E)采集了健康和衰退杨树树芯样品,进行实验分析后得到河北坝上地区杨树径向生长与气候因子关系数据集。该数据集包括:(1)河北坝上小叶杨防护林样地基本信息;(2)健康和衰退杨树标准年表及年表主要特征参数和公共区间分析结果;(3)健康和衰退杨树生长与气候因子关系分析数据,即,健康和衰退杨树年表与单月和季节尺度气候因子的相关性(月平均温度、月最高温度、月最低温度、月降水量、月平均相对湿度、帕默尔干旱指数)以及健康和衰退杨树年表与主要月份气候因子的滑动相关分析(月平均温度、月最高温度、月降水量、帕默尔干旱指数);(4)健康和衰退小叶杨树轮宽度时间序列及交叉定年检验结果。数据集存储为.txt、.xlsx、.out格式,由4个数据文件组成,数据量为404 KB(压缩为1个文件,152 KB)。

Tree-rings are considered an important record of the influence of the environment on plant growth. In July and August 2018, we collected and analyzed healthy and declining poplar tree rings in Bashang area of Hebei province, China. The dataset includes the following:(1) basic information on the Populus simonii shelterbelt plot in Bashang area of Hebei province;(2) standard chronologies of healthy and declining poplars and the main characteristic parameters and common interval spans;(3) correlations between healthy/declining poplars and climate factors: correlation analysis between healthy and declining poplars and monthly and seasonal climate factors(mean temperature, maximum temperature, minimum temperature, precipitation, mean relative humidity, and Palmer drought severity index) and moving correlation function analysis between the two chronologies and the seasonal and monthly climate factors for the most important months;and(4) time series and cross-dating test results for the healthy and declining Populus simonii forest. The dataset is archived in.txt,.xlsx,.out formats and consists of 4 data files with a data size of 404 KB(compressed into one single file with 152 KB).
