摘要:土壤水分是森林生态系统物质和能量循环的关键载体,对森林生态系统水文过程与水量平衡、养分循环、森林生产力形成及生态服务功能的发挥等具有重要作用。土壤水分含量是中国生态系统研究网络(CERN)陆地生态系统水环境长期定位观测的重要指标。马尾松针叶林(Pinus massoniana coniferous forest)、马尾松针阔叶混交林(mixed Pinus massoniana /broad-leaved forest)和季风常绿阔叶林(monsoon evergreen broad-leaved forest)是鼎湖山国家级保护区内分布的典型森林类型,长期以来受到严格的保护。依托鼎湖山森林生态系统定位研究站(鼎湖山站),依据CERN陆地水环境观测规范、质量保证与质量控制规范,分别于上述林型内设立标准观测样地,并开展森林土壤水分含量的长期定位观测、数据汇交、质控以及科研与示范工作。本数据集整理了鼎湖山站2002–2016年马尾松针叶林、马尾松针阔叶混交林和季风常绿阔叶林3种典型森林类型土壤含水量长期观测数据。以期为深入探究气候变化与植被覆盖变化影响下的森林生态系统结构与功能等相关议题提供本底资料,为该地区的森林经营管理及生态系统服务功能评价提供基础支撑。

Abstract & Keywords
Abstract: As a critical carrier of the material and energy cycle of forest ecosystem, soil moisture plays an important role in the hydrological processes, water balance, nutrient circulation, forest productivity formation and ecological function maintenance of the forest ecosystem. Soil moisture has been an important indicator of the water environment of the terrestrial ecosystems of Chinese Ecosystem Research Network (CERN). Typical forest types in Dinghu Mountain National Nature Reserve include Pinus massoniana coniferous forest, mixed Pinus massoniana/broad-leaved forest and monsoon evergreen broad-leaved forest, which have been for a long time under close protection. According to the CERN observation and quality control protocols, standard observation plots were set up in the above-mentioned forests by Dinghu Mountain Forest Ecosystem Research Station, where we carried out long-term in-situ observation, data collection, quality control, scientific research and demonstration work concerning forest soil-moisture-content. This dataset is an assemblage of the long-term observation data of soil moisture content of three typical forest types, including Pinus massoniana coniferous forest, mixed Pinus massoniana/broad-leaved forest and monsoon evergreen broad-leaved forest in DHS from 2002 to 2016. It provides critical information for in-depth studies of forest ecosystem structure and function under the background of climate change and vegetation change, supporting forest management and ecosystem service evaluation in this region.
