Abstract: Local climatic problems are widespread in cities under high-density and high-intensity construction mode in China, including heat island effect, poor ventilation, and frequent haze wea-ther. Urban blue-green space is vital for mitigating wind and heat, and for improving air quality, and therefore has become a hotspot of urban planning and design research dealing with climatic problems. Here, we reviewed the climate effects of urban blue-green space. In particular, we summarized the research progress of planning approaches to cool island landscape features optimization, cooling island configuration, ventilation corridor network connection and ventilation corridor interface control based on the levels of planning layout and network construction. We proposed a basic framework of urban blue-green space planning optimizing local climate by combining intelligent simulation platform, evaluation index system, planning and design guide, and guarantee mechanism for implement, aiming to provide key evidence for urban climate adaption and design.

Key words: urban blue-green space, local climate, cooling island, ventilation corridor, planning approach
