| 摘 要： | 利用最新森林资源二类调查数据,在确定合理的成熟龄基础上,模拟了不同调整期与轮伐期条件下每个林带的生长过程及年采伐量,通过对调整期末及轮伐期末龄级状态的比较,确定了吉林省西部农田防护林的调整期为20 a、轮伐期为35 a。经过调整和轮伐后,使农田防护林的年龄结构和面积结构适于可持续发展,更好地发挥防护效益。农田防护林更新模拟研究为编制森林经营方案提供了新的途径。

| Abstract: | Using the latest forest Inventory data,on basis of determining reasonable mature age of the farmland shelterbe,the growth process and annual cut was simulated under differerent regulating periods and rotations in this research. By comparison of the age-class status at end of regulation and rotations,reasonable regulation period and rotation were confimed 20 and 30 years,respectively.After a regulation period and rotation,the age and area proportion will be suitable to sustainable development and play a better protective benefit,and the present forest resource will be used in reason.This study will provide a new way to workout plan of forest management. |
