Simulation of the dynamics of a mangrove Kandelia obovata stand on Okinawa Island, Japan

本文报道了一株倒伏甘花（Kandelia obovata， S.， L.）的模拟动力学结果。冲绳岛万古湿地的勇林。本文在分析柞树结构和生理特性的基础上，模拟了50年的森林动态，并将模拟结果与实测树密度和平均树重数据进行了比较。在完全自疏期，相对生长率（RGR）与相对死亡率（RMR）之比一般在1.5左右。基于模拟结果，我们假设Manko湿地倒栽树林分的RGR/RMR在0 ~ 6 a的完全自疏前阶段大于1.5，在7 ~ 27 a的完全自疏阶段为1.5,27 a后在完全自疏后阶段有所波动。

We report the results of the simulated dynamics of a Kandelia obovata (S., L.) Yong forest at Manko wetland on Okinawa Island. Based on the structural and physiological properties of K. obovata, we simulated forest dynamics for 50 years and compared these results to field data sets measuring tree density and mean tree weight. In general, the ratio of the relative growth rate (RGR) to the relative mortality rate (RMR) is around 1.5 in the full-self-thinning phase. On the basis of the simulation results, we hypothesize that the RGR/RMR in the K. obovata stands at Manko wetland is greater than 1.5 in the pre-full-self-thinning phase from 0-6 years, is 1.5 in the full-self thinning phase from 7-27 years, and fluctuates in the post-full-self-thinning phase after 27 years.
