| 摘 要： | 根据广东省韶关市,吉林省长春市和山西省临汾市三个不同程度工业化城市（１９８６－１９９１年）的空气污染资料及同时期的森林覆盖率和人口资料,应用系统动力学建立了“城市森林对生态系统综合影响的仿真模型”,通过模拟试验,得到了保证城市居民健康的最佳森林覆盖率为：韶关市４７．４％;长春市３６．２％,临汾市３０．２％,从而为城市森林发展规划提供了决策依据。

| Abstract: | A simulating model"The comprehensive effects of urban forest on ecological system"was established on the basis of data.collected from 3 municipalities with different levels of industrialization during the period of 1986-1991. The municipalities were Shaoguan,Guangdong Province,Changchun,Jinn Province and Linfen,Shanxi Province. Optimum forest coverage rates for ensuring health of urban inhabitants were obtained by means of model test.They were 47.4% for Shaoguan,36.2% for Changchun and 30.2% for Linfen. These figures were used as basis for making decision in the planning of urban forest development. |
