AmeriFlux US-Dk1 Duke Forest-open field

This is the AmeriFlux version of the carbon flux data for the site US-Dk1 Duke Forest-open field. Site Description - The Duke Forest grass field is approximately 480×305 m, dominated by the C3 grass Festuca arundinacea Shreb. (tall fescue) includes minor components of C3 herbs and the C4 grass Schizachyrium scoparium (Michx.) Nash, not considered here. The site was burned in 1979 and is mowed annually during the summer for hay according to local practices. Lai, C.T. and G.G.

本数据集为站点US-Dk1杜克森林-开阔草地的美洲通量网（AmeriFlux）版本碳通量数据。
站点概况——杜克森林草地样地面积约为480×305米，以C3禾本科植物高羊茅（Festuca arundinacea Shreb.，即tall fescue）为优势物种，伴生有少量C3草本植物以及C4禾本科植物小须芒草（Schizachyrium scoparium (Michx.) Nash），本数据集未纳入后者。该样地于1979年经历过火焚烧，并按照当地农事习惯于每年夏季刈割以获取干草。
