Simulation of Thinning by Integrating Tree Competition and Species Biodiversity for Target Tree-Based Management of Secondary Forests

This study presents auxiliary support techniques for tree selection strategies based on the spatial structure indices and three competition in secondary forests, discusses importance of forest management. The parameter structured management is used as a quantitative index—the uniform angle index are design algorithm selective thinning forest. Based target tree-based principles, simulation was carried out using GIS C# programming languages. Data this were collected from experimental sample plots at Jilin Wangqing Forestry Bureau China. results strongly use technology scientifically selecting trees thinning, avoiding subjectivity traditional manual selection. Selection largely index. Hegyi’s its improved version provided almost identical results, i.e., intensities suggested by these first plot 21.8% 21.5%, respectively, second 21.3% 21.1%, respectively. Thus, one can be to select thinning. comprehensive (CCI, combination an with species mingling) avoid individual high mingling help maintain diversity. CCI suggests 18.3% 18.4% plots, Presented methods may provide supports scientific promote application information
