摘要:为探寻适合我国城乡生物多样性保护的有效措施和方法，以宝鸡城区为研究对象，通过实地调研和室内制图相结合的研究方法，创建一套融入植被结构因子（植被水平结构因子、植被优势种的年龄因子、植被垂直结构因子、林木类型因子）的生态单元分类系统，将研究区域内的城市绿地现状以图谱形式表示。通过对不同植被结构的绿地中维管束植物物种丰富度的对比，以检验此分类系统在城乡生物多样性信息采集中的有效性。基于制图信息和检验结果，分析研究区域内绿地空间结构存在的问题并针对宝鸡市城乡生物多样性保护提出相应策略，以期为今后我国城乡生物多样性保护提供理论依据和实践方法。



Abstract:In order to explore effective measures and methods suitable for biodiversity conservation in urban and rural areas in China, Baoji city was selected as a pilot study area. We created a set of biotope classification that integrated vegetation structure parameters, i.e. horizontal structure, age of dominant species, vertical structure, and forest types through field survey and biotope mapping. The status of urban green spaces was presented as a biotope map. By comparison of species richness of vascular plants in the green spaces with different vegetation structures, the validity of the biotope mapping scheme on the collection of urban and rural biodiversity information was examined. Finally, the existing problems in the spatial structure of green spaces in the study area were analyzed. A set of biodiversity protection strategies for the Baoji city was put forward for the theoretical basis and solutions to urban biodiversity conservation in the future.
