摘要:

针对四川盆地丘陵区农、林业生产特点和坡地农林复合系统特征,运用层次分析法(AHP) ,从结构、功能、效益方面设置评价指标,分别对系统中的6 种林带类型和10 种农作物复种方式进行综合评价,结果提出了3 种较好的林带类型( 即桤、柏混交和栎、柏混交- 灌- 草结构的林分以及桤木- 草结构的林分) 和4 种较好的农作物复种方式( 即小麦—花生、小麦/ 西瓜/ 蔬菜、蚕豆/ 玉米/ 红薯和蚕豆/ 西瓜/ 红薯等) ;为该区坡地农林复合系统机构优化提供科学依据。

Abstract:

Based on the feature investigatings of forest belt construction and agroforestry system on slope in the hilly region of Sichuan Basin, the evaluation indices of the structures, functions and benefits were selected, six types of the forest belts and ten multiple cropping subsystems in the agro forestry system on slope had been evaluated comprehensively with the AHP method. The results were as follows;three types of forest belts, i.e. H(herbs)-S(shrubs)- Cupressus mixed Alnus forest, H-S- Cupressus mixed Quercus forest, and H-S- Cupressus or Alnus forest, were better than other types in structure and function, four multiple cropping subsystems such as wheat peanut, wheat/watermelon/vegetable, broad bean/maize/sweet potato, and broad bean/watermelon/sweet potato, were better than the others in comprehensive benefits.
