边界空间绿化是开放性城市公园的重要因素，是衔接公园与城市绿地系统的重要措施。以广州天河公园“拆围透绿”工程为例，分析边界空间绿化存在通透性不足、与城市融合度不高、地域文化缺失、绿地管理不到位等问题，采用“保留、清杂、复绿”景观策略，确定点状、带状、片状景观3种绿化模式，制定“护栏+绿化”、绿化组团、“微地形+绿化组团”3种空间分隔手法，并从复绿植物种类选择、通透植物空间结构、活化林下消极空间、柔化公园边界空间、强化城市地域文化、加强空间绿化管理6个方面进行绿化提升，优化了公园的生态环境和开放性。

Border space greening is an important factor of open urban parks and an important measure to connect parks and urban green space systems. Taking Guangzhou Tianhe Park’s “demolition and greening” project as an example, this paper analyzes the problems of boundary space greening such as insufficient permeability, low integration with the city, lack of regional culture, and inadequate management of green space. The project adopts the landscape strategy of “preserving, clearing, and restoring green” to determine three greening models of greenspots, green belts and patches of green space, and to develop three space separation methods of “guardrail combined with greening”, greening group, and “micro terrain combined with greening group”. At the same time, greening improvement is carried out from six aspects, namely, the selection of greening plant species, the penetration of plant spatial structure, the activation of negative space under the forest, the softening of park boundary space, the strengthening of urban regional culture, and the strengthening of space greening management, which has optimized the ecological environment and openness of the park.
