Spatial Structure Dynamics and Maintenance of a Natural Mixed Forest

Spatial structure dynamics play a major role in understanding the mechanisms of forest and biodiversity formation. Recently, researches on spatial utilizing multi-period data have been published. However, these studies only focused comparative analyses living trees, without an in-depth analysis change processes. In this study, we propose new comprehensive method for dynamic at individual level, which includes three processes (living trees’ flow, mortality process recruitment process) that not considered previous researches. Four structural parameters (SSSPs, Uniform angle index, Mingling, Dominance Crowding) natural spruce-fir-broadleaf mixed with two-phase were taken as example to find out laws dynamics. All types named their proportions analyzed. The proportion changes SSSPs individuals was relatively high, even though mean values stand did considerably. five (0, 0.25, 0.5, 0.75, 1) are mutual flows typically one-step, three-steps four-steps being uncommon. higher influence than flow trees. created study can capture more features discovered earlier approaches, well guiding management some ways. Understanding nuances is critical part reasonable maintenance, should be focus future research efforts.
