Method for Generating Forest Landscapes Based on the Characteristics of Plant Distribution

doi:10.11947/j.AGCS.2018.20180102

Abstract

Abstract: The rapid generation of forest landscapes with specific spatial patterns in virtual geographic environment is a big challenge.Most of the previous studies specify the locations and attributes of trees using simulation and random synthesis methods.However,it is hard to reflect the distribution characteristics of each tree species for these methods.A graph-based neutral landscape model is proposed to generate forest landscapes with specific composition and spatial configuration based on landscape metrics set by users.The model converts a random map with many irregular regions into a region adjacency graph,and then generates patches with specific shape and size by merging neighbor nodes in the graph.Compared with other neutral landscape models,the proposed model has advantages of controllability and flexibility in expressing the landscape characteristics of different classes separately.Finally,based on the forest landscapes served as vegetation distribution maps,the positions and types of trees are determined.The proposed method can not only provide reasonable tree distributions for visualization of large-scale forests,but also reflect the spatial pattern of forest landscapes.The proposed method can also provide a reference for forestry planning and ecology research in virtual forest environment.

Key words: virtual geographic environments, neutral landscape model, plant distribution, region adjacency graph
