通过实地调查,对长汀策武银杏林下不同植物配置模式进行分类,按生产方式归类为林下种植,按经营模式将林下种植分为银杏-中药材,银杏-观赏花卉,银杏-经济花卉3种类别。根据生态学、景观学、经济学和社会学原理,采用层次分析法和主成分分析法,从生态效益、景观效益、经济效益、社会效益4个方面对7种具体模式进行综合评价。结果表明:生态效益较好的是银杏-黄花菜模式和银杏-杭白菊模式,景观效益较好的是银杏-杭白菊模式,经济效益较好的是银杏-杭白菊模式和银杏-望江南模式,社会效益较好的是银杏-杭白菊模式。综合评价结果显示,银杏-杭白菊模式效益最优,可作为先锋植物组合大面积推广种植。

Through field investigation,classification of different undergrowth plant configuration modes in Changting CeWu Ginkgo forest was done.According to the mode of production,they are divided into forest planting pattern,according to the business model,into three models,i.e.planting Ginkgo for traditional Chinese medicine,Ginkgo for ornamental flowers,Ginkgo for economic flowers.According to the ecology and landscape economics and sociology principle and by using AHP and PCA,the seven typical patterns from the ecological and landscape benefits,economic benefits and social benefits were evaluated.The results showed that the ecological benefit is Chrysanthemum morifolium mode and Hemerocallis citrine,landscape benefit is Ginkgo biloba-Chrysanthemum morifolium pattern,good economic benefit is Ginkgo-Chrysanthemum morifolium pattern and Ginkgo-Cassia occidentalis mode,better social benefit is Chrysanthemum morifolium.The results show that Chrysanthemum morifolium model has the best benefit and can be popularized as a pioneer plant for a large area.
