【摘要】 植物间互利作用的研究与探索有助于加强林业生产中的混交林建设,从而提高林分生产力。为了快速地模拟植物间互利作用下的生长情况,提出了一种利用植物间互利生长模型进行森林场景快速可视化的方法。该方法通过植物间互利指数、植物自身的生长率、植物当前生物量、环境条件等参数将Lotka-Volterra种间互利模型与植物个体生长模型进行融合,并采用像素化方法进行快速计算,以模拟互利植物的生长情况。通过水曲柳和落叶松混交林在不同的环境资源条件、分布密度、生长时间等条件下的可视化仿真,验证了基于植物间互利作用的森林生长模型快速计算方法的有效性和实用性。更多还原

【Abstract】 The research and exploration of reciprocity between plants can strengthen the construction of mixed forest,so as to improve the productive forces of forest.In order to simulate the growth of plants under reciprocity,this paper presented a rapid method of forest scene visualization.This method considers the plant benefit index,growth rate,plant biomass,plant current environmental conditions and other parameters.It uses a pixel method for the rapid calculation of Lotka-Volterra model and individual plant growth model,and simulates the plant growth in 3D space according to the dynamic change.Through simulating the mixed forest of ash and larch,the experimental results demonstrate that the approach to simulating the plant growth based on reciprocity is effective and practical.更多还原
