摘要:邊界空間綠化是開放性城市公園的重要因素,是銜接公園與城市綠地系統(tǒng)的重要措施。以廣州天河公園“拆圍透綠”工程為例,分析邊界空間綠化存在通透性不足、與城市融合度不高、地域文化缺失、綠地管理不到位等問題,采用“保留、清雜、復(fù)綠”景觀策略,確定點(diǎn)狀、帶狀、片狀景觀3種綠化模式,制定“護(hù)欄+綠化”、綠化組團(tuán)、“微地形+綠化組團(tuán)”3種空間分隔手法,并從復(fù)綠植物種類選擇、通透植物空間結(jié)構(gòu)、活化林下消極空間、柔化公園邊界空間、強(qiáng)化城市地域文化、加強(qiáng)空間綠化管理6個(gè)方面進(jìn)行綠化提升,優(yōu)化了公園的生態(tài)環(huán)境和開放性。

Abstract: 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 Parks “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.
Key words: Greening mode; Remove the enclosure and make it green; Boundary space; Urban park
城市公園作為城市綠地系統(tǒng)的重要組成部分,能展現(xiàn)城市文化、生態(tài)面貌、環(huán)境質(zhì)量,其建設(shè)和開放程度體現(xiàn)了城市文明和宜居的程度。廣州城市公園數(shù)量多且類型豐富,其開放先后經(jīng)歷了向游人免費(fèi)開放,“拆墻透綠”行動(dòng),城市公園與綠道網(wǎng)絡(luò)建設(shè)統(tǒng)籌,和“拆圍透綠”行動(dòng)4個(gè)階段[1~2]。拆圍透綠,又稱“破墻透綠”“破圍透綠”,是指通過利用欄桿、綠化等外圍包裝來代替現(xiàn)有的圍墻,達(dá)到隱形圍墻的目的[3]。城市公園邊界空間是公園與城市環(huán)境交界的空間地帶,具有空間復(fù)雜、表現(xiàn)形式豐富等特點(diǎn)[4]。邊界空間綠化配植不但能將公園環(huán)境融入城市綠地系統(tǒng),更能將城市文化滲透到公園,其在城市公園開放性建設(shè)中起著重要地位。……
