摘　　要：【目的】研究衡阳市滨水绿地的生态效应,为植物造景和景观质量评价提供理论依据。【方法】以衡阳市典型片状和带状滨水绿地为研究对象,分别按乔-灌-草型、乔-灌型、乔-草型、灌-草型、乔木型、灌木型、草本型等7种种植结构,定点定时测定绿地中心和对照点的光照、温度、湿度和CO_(2)浓度。【结果】(1)在片状或带状绿地中,乔-灌-草型种植结构的遮荫效果、调节空气温度的效应以及释氧固碳能力最强,乔-草型种植结构的空气增湿效应最大,而草本型生态效应最差;(2)种植结构相同,片状结构的遮荫、降温、增湿以及调节CO_(2)浓度的能力显著高于带状绿地(P<0.05)。【结论】在相同种植结构中,片状绿地的生态效益大于带状绿地,复层结构的生态效益大于单层结构。【Objective】The ecological effect of waterfront green space in Hengyang City was studied to provide a theoretical basis for plant landscaping and landscape quality evaluation.【Method】Taking the flake green space and belt green space of typical waterfront green space in Hengyang City as the research object,we surveyed the light,temperature,humidity and CO_(2) concentration in the green space centre and control point according to seven planting patterns of tree-shrub-herb,tree-shrub,tree-herb,shrub-herb,tree,shrub and herb at fixed time and location,respectively.【Result】(1)In flake green space or belt green space,the capacity of shade,air temperature regulation,carbon fixation and oxygen release of tree-shrub-herb planting pattern,and the effect of air humidity-increasing of tree-herb planting pattern were the strongest,while herbal ecological effect was the weakest;(2)In the same planting pattern,the capacity of shade,temperature-decreasing,humidity-increasing and CO_(2) concentration regulation of flake green space was significant higher than that of belt green space(P<0.05).【Conclusion】The results showed that in the same planting pattern,the ecological effect of flake green space were bigger than that of belt green space,and the ecological effect of multicoat structure were bigger than that of singlecoat structure.
