摘要:森林地被物层(枯落物和苔藓)和土壤对森林生态系统水源涵养和水文调节等服务功能的发挥起着关键性作用。位于青藏高原东部的岷江源头区森林水源涵养功能变化对整个岷江流域,乃至长江上游的生态环境建设与水资源安全保障都有重要意义。通过野外调查和室内分析实验,本数据集整合了岷江源头区一个典型的针叶林—灌丛交错带地被物储量、最大持水量以及0–20 cm土壤容重、最大持水量、毛管持水量数据。本数据集可为进一步认识长江上游区域生态水文效应提供基础数据,对区域森林可持续经营与管理、改善区域水环境有重要意义。

Abstract & Keywords
Abstract: Ground covers (i.e. litter and moss) and soils play a key role in water conservation and hydrological regulation of forest ecosystem. The changes of forest water conservation function in the source area of Minjiang River on the eastern Qinghai-Tibet Plateau are of great significances to the ecological environment construction and water resource security of the whole Minjiang River basin and even the upper reaches of the Yangtze River. Through field investigation and laboratory experiment, this dataset integrates the storage and maximum water holding capacity of ground covers and the bulk density, maximum water holding capacity and capillary water holding capacity of 0–20 cm soils of a typical alpine forest-shrub ecotone in the source area of Minjiang River. It is expected to provide scientific basis for further understanding the ecohydrological effect of the upper reaches of the Yangtze River, which is of great significance for sustainable management and water environment improvement of the regional forest ecosystem.
Keywords: Qinghai-Tibet Plateau; water conservation; litter; moss; soil; forest-shrub ecotone
