摘 要:利用通讯及网上查询法对北京市101个苗圃的区位、规模、性质、销售区域情况进行了宏观分析,利用典型抽样和实地踏查法对其中20个苗圃的在圃苗木物种构成特征、株数、规格以及苗木重要度进行了详细分析。结果表明,北京市苗圃在近郊区较为集中,调查到的在圃苗木共232种,隶属63科123属。常绿与落叶种数比为1:6,数量比为1:4;苗木株数随着规格的增大呈递减趋势,大规格苗木数量紧俏。北京市苗圃尚存在规模化数量不足、苗木结构不够合理、经营特色不突出等问题,未来发展趋势应为苗圃规模化的提升、标准化的制定、特色化的定位及乡土树种的开发等。Through communication and Internet searching, the locations, scales, properties, sales areas of 101 nurseries in Beijing were analyzed macroscopically. Using the typical sampling and field survey method, 20 nurseries' species composition characteristics, numbers, specifications and importance degrees of seedlings were analyzed in detail. The results showed that Beijing city nursery is more concentrated in the suburban areas, 232 species in total, belonging to 63 families and 123 genera. The proportion of evergreen and deciduous species is 1:6 and the number proportion is 1:4. The number of seedlings with specifications increasing showed a decreasing trend, the number of large size seedlings in short supply. Beijing nursery stock enterprises still exist problems such as scale shortage in quantity, nursery stock structure is not rational, characteristics are not prominent and so on. Scale enhancing, standardized formulation, characteristics positioning, development of native tree species are the future development tendency.
