摘　　要：通过对江苏沿海滩涂较具代表性的银杏采叶园 (A)、银杏果—叶—农复合园 (B)、银杏材—农复合园 (C)等 3种不同银杏 -农作物复合系统种群复合结构、植物个体的生长结构、现实生态位、生物多样性的比较分析 ,研究了不同复合系统的种群动态特征。结果表明 ,银杏果用 -叶用 -豆科作物复合模式具有较大的生物多样性指数和较小的断面积密度指标值 ,同时具有利于间作种群共存的冠层结构和根系结构 ,便于调节种群动态和技术集成管理 ,是一种适宜在海岸带地区推广的优化复合经营模式。The characteristic of population structure in three types of typical agroforestry models,namely,the model of Ginkgo biloba leaf utilization garden(A),the model of Ginkgo biloba leaf and fruit utilization crop garden(B) and the model of Ginkgo biloba wood utilization crop garden(C),commonly practiced in the seacoast in Jiangsu Province,were studied by anaylysing the compound structure and growth structure of plant,the realized niche and biodiversity.The results are as follows:The Ginkgo biloba leaf and fruit utilization Leguminous crop compound model have the largest value index of species diversisty and the smallest relative basal area.Furthermore,it also has the optimum horizontal and vertical structure and it can be applied in Chinese seacoast.
