Net Primary Production from a Subtropical Pasture, South East Queensland Peri-Urban SuperSite, Samford, 2011-2013

Pasture growth was estimated by taking biomass cuts at roughly monthly intervals from a subtropical pasture at the location of the eddy covariance tower on the Samford Ecological Research station. The pasture was dominated by paspalum dilalatum and several native species. Cuts were taken at 4 random locations of the 5 ha pasture and separated into live and dead components and analysed for dry matter production.

本研究通过刈割采集生物量样本的方式，以约每月一次的间隔，在萨姆福德生态研究站（Samford Ecological Research station）的涡度协方差塔（eddy covariance tower）所在的亚热带牧场中开展采样，以此估算牧草生长量。该牧场以宽叶雀稗（Paspalum dilalatum）及多种本土物种为优势群落。研究人员在这片5公顷的牧场内随机选取4个采样点，将采集到的样本划分为活体组分与枯亡组分，并对其干物质产量进行分析测定。
