Global woodland structure from local interactions: new nearest-neighbour functions for understanding the ontogenesis of global forest structure

Forest Ecosystems

Table 1 Basic characteristics of the four example research plots. D – Daqingshan forest region, J – Jiaohe forest region, JS – Jiulongshan Forest, XS – Xiaolongshan Forest. \( \hat{\overline{M}} \), \( \hat{\varPsi} \), \( \hat{\overline{T}} \) and \( \hat{Y} \) were calculated for k = 4 neighbours
