Douglas-fir accounted for over 75% of the total average basal area (39.1...

Disaggregative and individual-tree growth models in theory and application

Creator:

Ritchie, Martin W.

Abstract:

Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...
