2002-2020年鼎湖山森林小流域地下水位数据集

A dataset of groundwater level in the small watershed of Dinghushan Forest(2002-2020)

地下水是流域水文循环过程中的重要组成部分之一,其动态变化对于认知陆地生态系统的水文调节机制、物质元素循环过程以及生态系统服务功能等具有重要价值。鼎湖山国家级自然保护区内包含亚热带季风常绿阔叶林及其过渡植被类型,自20世纪50年代以来受到严格保护。鼎湖山森林生态系统定位研究站依据陆地生态系统水环境观测规范和质量控制要求,在鼎湖山自然保护区完整集水区的下游布置了4个地下水位观测井系统,对地下水埋深进行规范化的长期定位观测。本数据集整理了2002-2020年4个地下水位观测井长期监测数据,以期为全球气候变化背景下地下水响应过程研究、森林生态系统水文服务功能评估、森林资源的可持续经营管理等提供基础数据支撑。

Groundwater is one of the important components in the hydrological cycle of the basin.Its dynamic change is of great value for understanding the hydrological regulation mechanism,the cycle of material elements and ecosystem service function of terrestrial ecosystem.Covered with subtropical monsoon evergreen broad-leaved forest and its transitional vegetation types,Dinghushan National Nature Reserve has been well protected since the 1950s.Dinghushan Forest Ecosystem Research Station set up four groundwater level observation wells downstream of the complete catchment area of Dinghushan Nature Reserve according to the observation specifications and quality control requirements of terrestrial ecosystem water environment,so as to carry out long-term standardized positioning observation of the depth of groundwater level.This dataset collates the long-term monitoring data of four groundwater level observation wells from 2002 to 2020.It is aimed to provide basic data support for the study of groundwater response process,the evaluation of hydrological service function of forest ecosystem and the sustainable management of forest resources under the background of global climate change.
