城市绿道是城市绿地生态系统的绿色骨架,对维护城市生态安全具有重要意义。城市绿道综合效能评价是构建科学合理的城市绿道的基础和前提,更是最佳路径和节点选择的重要方法和手段。文章应用特尔斐专家评价法,从城市绿道路径和城市绿道景观节点两个不同层面系统地建立了济南城市绿道的综合指标体系,对济南市党家片区和老城片区进行了综合效能评价,选择出最佳的连接路径和景观节点。结果表明:党家片区连接路径综合指数一级的有104国道等2条,二级的有重汽路等2条;景观节点综合指数一级的有党东清真寺等6个,二级的有撅山等2个。老城片区连接路径综合指数一级的有护城河等5条,二级的有历山路等4条;景观节点综合指数一级的有趵突泉等8个,二级的有珍珠泉公园等6个。党家片区综合指数>2.00的最佳连接路径为104国道等,老城片区综合指数>2.00的最佳连接路径为护城河等;党家片区综合指数>1.50的最佳景观节点为党东清真寺等,老城片区合指数>2.50最佳景观节点为趵突泉公园等。
Urban greenway is the green skeleton of the urban greenland ecosystem, which is of great significance to the maintenance of urban ecological security. The evaluation of comprehensive effectiveness of urban greenway is the foundation and premise for building a scientific and rational urban greenway, and it is also an important method and means for selecting the best path and node. Based on the Delphi expert evaluation method, this paper systematically establishes the comprehensive index system of urban greenway in Jinan from two different levels of urban greenway path and urban greenway landscape node, and synthesizes the Dachang Area and Old City Area of Jinan City Efficiency evaluation, choose the best connection path and landscape node. The results show that there are two national highways such as 104 State Road at the level of the comprehensive index of connection path in Party Area, two with heavy truck road at grade two, six with Party East Mosque at the level of comprehensive index of landscape node, There are 2, such as Dangshan. There are 5 moats and 2 Youlianshan Road at the integrated index level of the Old Town Area. There are 8 Baotu Spring at the level of the comprehensive index of the landscape node. There are Pearl Springs Park Six other. The best connection path for Party Area Composite Index> 2.00 is 104 State Road, etc. The best connection path for the Old City Area Composite Index> 2.00 is the moat, etc. The best scenic node for the Party Area Composite Index> 1.50 is the East Mosque, etc. , The old city area coincidence index> 2.50 best landscape node Baotu Spring Park.
