摘要通過實地調(diào)查,結(jié)合資料研究,分析總結(jié)深圳在城市化加速發(fā)展背景下形成的鄉(xiāng)土植物資源保護和利用特色,包括建設(shè)郊野公園和海岸休閑帶,古樹名木及風(fēng)水林地的就地保護,城市公園及道路綠化中的大量選用;提出加強原生群落及古樹名木保護、城市綠化建設(shè)中推廣鄉(xiāng)土植物,以及在城市更新與舊城改造中“給樹讓路”等保護與利用鄉(xiāng)土植物資源的對策。

AbstractBased on field investigation and data analysis, the characteristics of local plant resources protection and utilization in Shenzhen under the background of urbanization accelerated development were analyzed and summarized,including the construction of country parks and coastal leisure belt, the protection of ancient and famous trees and Feng Shui woodland, and large selection of urban parks and road greening. The paper puts forward some countermeasures to strengthen the protection of native communities and the protection of old and famous trees, the promotion of native plants in the construction of urban greening, and the protection and utilization of native plant resources in the process of urban renewal and transformation of old cities.

深圳是我國改革開放的窗口,在城市建設(shè)方面基本實現(xiàn)了社會、經(jīng)濟與環(huán)境的協(xié)調(diào)發(fā)展[1]。在建設(shè)與開發(fā)中保證生態(tài)環(huán)境良性循環(huán)及可持續(xù)發(fā)展是擺在城市建設(shè)與管理者面前的重大課題。目前,國際城市綠地建設(shè)與管理的發(fā)展趨勢是對城市生物多樣性的保護及持續(xù)利用[2]。鄉(xiāng)土植物又稱為本土植物,廣義的鄉(xiāng)土植物可以理解為經(jīng)過長期的自然選擇及物種演替后,對某一特定地區(qū)有高度生態(tài)適應(yīng)性的自然植物區(qū)系成分的總稱[3]。據(jù)研究,在園林建設(shè)中,與外來植物相比,鄉(xiāng)土植物不僅在維護中較少需要外部支持[4],并能更好地支持生物多樣性,維持城市生態(tài)系統(tǒng),而且突出景觀特色。因此,在城市化加速發(fā)展的背景下,總結(jié)研究深圳鄉(xiāng)土植物資源的利用和保護特色有利于提升深圳市生態(tài)環(huán)境質(zhì)量和實現(xiàn)城市園林植物多樣性的可持續(xù)發(fā)展,為熱帶亞熱帶濱海城市的園林建設(shè)提供參考。……
