    摘要:近年来,全国各城市绿化面积不断扩大,质量不断提高,绿化领域不断创新。鉴于现行绿化统计指标存在统计口径不一等问题,未能很好地反映近年来绿化的质与量的变化。以广州市为例,提出了在充分认识到绿化覆盖率对城市生态安全的重要性的同时,城市绿化评价应增加林木绿地率和增加碳汇、水体及立体绿化、生物多样性和绿化服务功能等方面的指标,以构建更加切合实际的评价系统。

    Abstract:In recent years, the urban greening area in each city of China has been expanding, the quality of greening area has been improving, and the field of greening has been innovating. As current greening statistical indexes were diversified in different regions, it failed to reflect the changes of greening quantity and quality. With Guangzhou as an example, this article has put forward that when the importance of green coverage ratio to urban ecological security has been fully recognized, urban greening measure index should use ratio of forestry green space, and add carbon sink, water body greening, vertical greening, biological diversity, and greening service function as new indexes, in order to construct more practical evaluation system.
