Assessment of plant species diversity of ancient tea garden communities in Yunnan, Southwest of China 总被引:1,自引:0,他引:1
Ancient tea garden has existed in Lancang County, Yunnan Province for more than 1,300 years, and is regarded as the provenance of Pu’er Tea’s seed source. The ancient tea garden ecosystem is a typical model that integrates conservation biodiversity and utilization of natural resources. In order to reveal the role of biodiversity conservation of this ecosystem, plant diversity and application value of ancient tea gardens, normal tea gardens and secondary forestry communities in Lancang County were surveyed and compared. 360 households investigation were also conducted by using household-based agro-biodiversity assessment (HH-ABA). The results showed: (1) Ancient tea garden communities have high biodiversity, whose plant species diversity (H = 3.03) is lower than that of secondary forestry (H = 4.59) and higher than that of normal tea garden (H = 2.62); (2) Life forms analysis of plant species showed the vertical structure of the ancient tea garden communities are intact, herbs, trees, shrubs, vines, epiphytes are included, which is similar to that of secondary forest, while normal tea garden is dominant by herbs and no trees; (3) A large number of protected species, including five endangered, seven vulnerable and three rare, is well conserved in the ancient tea garden, while no protected species were found in secondary forest and normal tea garden; (4) The analysis of agro-biodiversity revealed that 56 % of plant species in the ancient tea garden are effectively used by households, while no plant except tea trees is used in normal tea garden; (5) The integrated values of ancient tea garden and normal tea garden illustrated that both biodiversity conservation and economic income of ancient tea garden are higher than that of normal tea garden. We suggest that the local peoples’ knowledge and experience on resource management and utilization should be well documented and encouraged, and effective conservation and reasonable utilization of ancient tea garden would be achieved through training and demonstration with the participation of the local government, research institution and farmer. 相似文献

园林植物是城市园林景观系统的重要组成部分,是发挥园林功能和绿化效益的重要因子,在城市绿化景观建设中具有不可替代的作用。园林植物体能挥发出多种不同的挥发性物质,它能杀灭空气中细菌或者抑制其生存空间,从而达到净化空气的作用。因此,为探求吉林市内现有植物造景中不同园林灌木的抑菌效果,本文采用了自然沉降法对吉林市内园林灌木的抑菌效果进行了较为系统的分析研究,以便为植物造景、园林绿化等设计中提供理论参考。 相似文献

随着"生态园林"理念的不断深入,人们对园林绿化的概念、内涵也提出了更高的要求,体现在各植物元素的和谐统一上。实现绿化生态效益的最大化要根据绿地周围的城市景观元素,更多地把绿地景观融入到整个城市环境中,使人工景观与自然景观更加自然地交融在一起,优化植物配置,张扬城市园林个性,做到人与自然和谐共处,用可持续发展观建设生态人居城市,构建和谐园林。 相似文献
