摘要

在北京平原造林项目区内的大兴区,对永定河沿岸沙地、六环内拆迁腾退地和中东部壤土地的林木保存率、树高、冠幅等指标进行树种适应性及配置研究。研究结果表明:1)永定河沿岸沙地,刺槐、千头椿、香花槐、新疆杨、金叶榆、金叶槐、法桐、毛白杨、栾树、旱柳和107杨等11个树种生态适应性较好,银杏和楸树次之,五角枫最差;2)六环和内拆迁腾退地,国槐、栾树、刺槐、白蜡、银杏、金叶榆和楸树7个树种生态适应性较好,玉兰泡桐次之,水杉、法桐和杜仲最差;3)中东部壤土地,刺槐、国槐、窄冠毛白杨、银杏、山杨、毛白杨、白榆和金叶榆等8个树种生态适应性较好,白蜡和栾树次之,法桐和臭椿最差。3种立地类型均按照相邻地块树种高度相近原则配置。
        In the plain afforestation project area of Daxing District of Beijing,the three site types are selected from the sandy land along the Yongding River,some landaresa inside the sixth-ring road and the east-central loamy land.The study of tree species conservation and allocation is based on the forest conservation rate,tree height and crown width.Preliminary conclusions are drawn:1)In the sandy land along the Yongding River,the ecological adaptation of eleven species including Robinia pseudoacacia,Ailanthus altissima,Robinia pseudoacacia cv.idaho,Populus albavar.pyramidalis,Ulmus pumila cv.jinye,Sophora japonica cv.Golden Stem,Platanus acerifolia,Populus tomentosa,Koelreuteria paniculata,Salix matsudana and 107 Populas L.is good,followed by Ginkgo biloba and Catalpa bungei and Acer mono is worst.2)In the sixth-ring demolition,the seven tree species including Sophora japonica,Koelreuteria paniculata,Robinia pseudoacacia,Fraxinus chinensis,Ginkgo biloba L,Ulmus pumila cv.jinye and Catalpa bungei have good ecological adaptability,followed by Magnolia denudata and Paulownia,and the ecological adaptability of Metasequoia glyptostroboides,Platanus acerifolia and Eucommia ulmoides Oliver is worst.3)In the east-central loamy land,eight species of Robinia pseudoacacia,Sophora japonica,Populus tomentosa,Ginkgo biloba,Populus davidiana,Populus tomentosa,Ulmus pumila.,and Ulmus pumila cv.jinye.have better ecological adaptability,followed by Fraxinus chinensis and Koelreuteria paniculata.Platanus acerifolia and Ailanthus altissima have the worst ecological adaptability.The three site types are all arranged according to the principle that the heights of adjacent tree species are similar.
