摘要
运用数量化模型Ⅲ对影响农田防护林生产力水平的树种、立地条件、结构配置及林带栽植方向等进行了评价,为今后农林复合生态系统中防护林的建设及进一步的发展提供了一定的科学依据。
This paper makes evaluation on the tree species, site conditions, structural configuration, and forest belt planting methods, etc. that have influence on the productivity level of the farm fields' protective forest by using the quantified model Ⅲ, which provides certain scientific basis for the construction and further development of the protective forest of the future agriculture and forestry compound ecological system.
