| 摘 要： | 以大连城市森林资源为研究对象,运用系统动力学原理和方法,通过动态系统仿真模型的构建,对大连城市森林生态效益动态进行了仿真。该生态效益系统模型共选取199个变量、105个常量,其中9个状态变量,27个流速变量。该模型对2005-2025年间各种生态效益的变化趋势进行仿真。仿真结果为大连城市森林规划、合理开发利用森林资源提供数据资料,为森林资源的保护和管理提供决策的依据。 |

| Abstract: | Taking the urban forest resource in Dalian city as the research objective,the authors carried out the studies on dynamic simulation of ecological benefit of urban forest.The dynamic simulation model is developed guided by the principle of system dynamics.This ecological benefit model refers to 199 variables and 105 constants,of which including 9 state variables and 27 flow variables.The variations of eco-benefit from 2005 to 2025 are simulated with this model.The simulated results are referential to the urban forest planning,forest resource utilization,forest protection and to the decision making. |
| Keywords: | system dynamics system simulation ecological benefit |
