2012–2016年湖北神农架森林生态系统国家野外科学观测研究站地下水位数据集

A dataset of groundwater level at National Observation and Research Station for Forest Ecosystems in Shennongjia(2012–2016)

地下水是一个地区重要的自然资源,地下水位数据可为研究地下水的长期变化提供重要的参考资料。本数据集收集整理了湖北神农架森林生态系统国家野外科学观测研究站(简称神农架站,SNF)采用人工记录方法观测的2012年6月至2016年12月地下水位埋深数据,共计1675条记录。为了便于用户了解本站地下水位的概况(如平均埋深及其变化),我们计算了神农架站地下水位埋深的平均值及其标准差、累计月动态、年际变化及趋势。地下水井设置于神农架站树木园,海拔1290 m。每天20:00测定地下水位埋深。初步分析表明,神农架站的地下水位有下降的趋势。但同期的降水量并未减少,且略有增加的趋势。地下水位下降的原因待持续观测及进一步深入分析。

Groundwater is an important natural resource in a region,and the data of groundwater level can offer significant references for studying the long-term changes of groundwater.This dataset consists of groundwater level data recorded manually from June 2012 to December 2016 at National Observation and Research Station for Forest Ecosystem in Shennongjia,Hubei,China(also known as Shennongjia Biodiversity Research Station of Chinese Academy of Sciences,SNF for short),with a total of 1,675 entries.In order to facilitate users to understand the general situation of groundwater level of this site,such as average depth and its changes,we calculated the mean value,standard deviation,accumulated monthly dynamics,annual variation and trend of the groundwater level depth.A groundwater well was set up in the tree garden of SNF at an altitude of 1,290 m.The distance from the level of groundwater to the ground plane was measured at 8:00 p.m.every day.Preliminary analysis shows that the groundwater level of SNF has a downward trend.However,the precipitation during the same period has not decreased,but slightly increased.The causes of the decline in the groundwater level of SNF are subject to long-term observation and further in-depth analysis.
