Data for: Comparison of steady state and transient parameterization of unsaturated models for Sphagnum moss
收藏资源简介:
Data were collected from the experimental Spahgnum fibre farming station in Shippagan, New Brunswick during the 2013 field season. In situ measurements of soil moisture profiles from two experimental plots of different aged Sphagnum moss in a restored cut-over peatland, measured using CS605 TDR probes. Meteorological and water table were also collected hourly. Retention: Samples of Sphagnum moss (n = 2 per profile) and cut-over peat (n = 1 per profile) were taken from the top 10 cm, the base of the moss profile and the cut-over peat of each plot; depths represent the midpoint of 5 cm samples. Soil water retention and unsaturated hydraulic conductivity were the determined in the laboratory (Taylor and Price, 2015) using the modified tension disk method (McCarter et al., 2017; McCarter and Price, 2014). Following that, bulk density, porosity, and saturated hydraulic conductivity were measured (Taylor and Price, 2015).
本数据集采集于2013年野外季,采自加拿大新不伦瑞克省希帕根(Shippagan)的实验性泥炭藓(Sphagnum)纤维种植站。在一处经修复的采挖泥炭湿地中,针对两个种植不同生长年限泥炭藓的实验样地,采用CS605型时域反射(TDR)探针开展了原位土壤湿度剖面测量。同时以每小时1次的频率采集气象数据与地下水位数据。 持水特性样品采集:每个样地分别从0~10 cm土层、泥炭藓剖面底部以及采挖泥炭层中采集样品,其中泥炭藓样品每个剖面采集2份,采挖泥炭样品每个剖面采集1份;采样深度为5 cm土样的中点位置。 实验室测定环节首先采用改进型张力圆盘法(McCarter等,2017;McCarter与Price,2014)测定了土壤持水性与非饱和导水率(Taylor与Price,2015);随后又测定了容重、孔隙度与饱和导水率(Taylor与Price,2015)。
