【摘要】 为全面深入探讨宝华山生物多样性保护和群落演替，以及地带性植被恢复方向。根据植物物候期，在不同季节采用样线和样方相结合的方法进行野外实地调查，同时查阅相关资料，编制宝华山种子植物名录，并对其区系组成、性质及未来植被动态演替方向进行了详细分析。结果表明：该区共有种子植物138科558属966种；生活型以草本为主，共589种；乔木、灌木和木质藤本分别有183,166种和28种;10种以上的科有19个，共有286属535种，分别占研究区域种子植物总属数和总种数的51.16%和55.27%;植物区系在科水平上以泛热带和北温带为主，而属水平上温带成分占优势，表现出一定的过渡性；植物区系与邻近地区比较和基于气候预测的植物区系动态预测分析均显示与低纬度的宜兴关系最为密切。更多还原

【Abstract】 In order to comprehensive and in-depth discussion on biodiversity protection and community succession in Baohuashan as well as the restoration direction of zonal vegetation, according to the plant phenology period, field surveys are conducted using a combination of sample lines and sample quadrats in different seasons, at the same time, relevant information is consulted, a list of seed plants in Baohuashan is compiled, and its flora composition, nature and the future vegetation dynamic success direction are analyzed in detail. The results show: in this region, for seed plants, we found 138 families, 558 genera with a total of 966 species; as for life form, major in herbal, totally 589 species; 183, 166 and 28 species, respectively for arbors, shrubs and woody wines; 19 dominant families(with at least 10 species for each), totally 286 genera and 535 species which making up 51.16 % and 55.27 % of the total genera and total species of seed plants in this region, respectively. On flora, pan tropics and north temperate are the dominant elements at the family level, while temperate elements dominate at the genus level, presenting certain transitional nature. As for flora, through comparison with the adjacent district and through flora dynamic prediction and analysis based on climate prediction, both show that it is most closely related to the low-latitude Yixing.更多还原
