摘　　要：土壤水分作为陆地生态系统水循环和植被生长发育的重要因子,在森林生态系统和水文过程等方面发挥了重要的作用。贡嘎山站是立足青藏高原东南缘及横断山区,以多层次的山地生态系统为主要研究对象的综合观测试验研究站,区域内生态系统的自然性保持完好、山地环境要素多样、生物多样性丰富,是开展山地森林生态系统研究最理想的场地。按照CERN的统一规范,贡嘎山站开展了土壤水分含量长期监测工作。本数据集收集整理了2007–2017年峨眉冷杉成熟林、峨眉冷杉演替中龄林、峨眉冷杉冬瓜杨演替林和3000米气象观测场的土壤含水量数据,这对了解气候变化下该区域森林土壤水分动态特征及其响应变化提供了数据支撑,对区域森林生态系统森林水量平衡、森林生产力形成及生态服务功能具有重要意义。As an important factor of hydrological cycle of terrestrial ecosystem and vegetation growth,soil water lays an important role in forest ecosystems and the hydrological processes.Gongga Mountain station is a comprehensive observation and experimental research station based on southeastern Qinghai-Tibet Plateau and the Hengduan Mountain region,focusing on multi-level mountain ecosystem as the main research object,and is an ideal site for the study of mountain forest ecosystem due to its intact nature,diverse mountain environmental elements and rich biodiversity..Pursuant to the protocols for standard soil observation and measurement of CERN,the Gongga Mountain station has been carrying out long-term monitoring of soil moisture content.This dataset collected and processed soil moisture content of mature Abies fabri forest,middle-aged A.fabri forest,succession forest of A.fabri and Populus purdomii,and the meteorological station of 3000 m.This provides data for understanding the soil moisture dynamic characteristics and its response to climate changes in this region.It is of great significance to the water balance,forest productivity,and ecological function maintenance of regional forest ecosystem.
