城市绿地类型的划分及其在生态城市建设中的意义和作用

根据生境和绿地功能把城市绿地划分为10个类型，并阐述了这些类型的组建和管护问题。10个绿地类型包括保护区，植物园，城市公园，城市片林，街心花园、草坪和花坛，道路两旁绿化区，庭园绿地，房顶、墙壁、凉台和室内的绿化，村落生态经济园及生态农业景观。根据归属部门、管理级别、保护对象、管理对象及监控类型的不同，对保护区进行了进一步的划分。城市绿地分类系统的建立既能把城市建设与生物多样性保护相结合，也有助于生物多样性公约的实施，并在维护城市生态安全、美化城市环境、建立具有特色的生物多样性产业、开展生态旅游和生态教育培训、繁荣地方经济和提高当地人民生活水平等方面有重要意义。

Classification of urban green space types and its significance and role in ecological city construction

According to various habitats and their functions, the urban green spaces could be classified into ten types： protected area; botanical garden; urban park; urban forest; street garden, lawn and parterre;roadside green belts;garden green area; roof, wall, terrace and indoor green area;rural ecoeconomic garden and eco-agricuhural landscape. And the construction, management and protection of these types of green spaces were discussed. The protected area could be furtherly divided into different subtypes according to administrative authority, administrative level, protected object, managed object and supervisory type. The establishment of the classification system of urban green spaces can not only combine urban construction with bio-diversity protection, but also be helpful in implementing the Convention on Biological Diversity. And it can also play its role in defending regional ecological safety, beautify!ng urban environment, building bio-diversity industry, developing ecotourism and ecological education, promoting local economic prosperity and improving the living standard of the local people.
