摘 要:运用景观生态学的原理、方法及3S技术,依据合肥市环城公园特点,采用样方法和Citygreen软件对公园的景观特征进行了计算,分析生态风景林斑块及其生态功能。结果表明:环城公园内生态风景林景观斑块面积65.44hm2,占整个景观的43.91%;一般绿地景观斑块面积1.39hm2,占整个景观1%;水体景观斑块面积53.38hm2,占整个景观35.82%;裸地景观斑块面积1.13hm2,占整个景观0.76%;建筑及硬质铺装面积25.82hm2,占整个景观17.33%,说明生态风景林已具有较高的环境控制能力。公园内以木本植物为主的群落结构表现相对稳定,丰富了城市景观资源,形成了城市特色景观风貌。环城公园生态风景林的生态功能体现在:固碳效益折合人民币价值约8050407元;清除有害气体总价值约271164元;有效截流暴雨径流总量34162.85m3,价值约18468438元;对改善和维持合肥市中心城区生态环境起着重要作用。Based on the theory and methodology of landscape ecology,the landscape structure and the environmental functions of the urban eco-landscape forest in the ring park around Hefei City were analyzed by using the technique of GIS and CITYgreen software. Results showed that there were 5 major landscape elements,i.e. eco-landscape forest,general green space,water space,naked space,and building and hard pavement surface,accounting for 43.91%,1.00%,35.82%,0.76%,and 17.33%,with an area of 65.44,1.39,53.38,1.13,and 25.82hm^2,respectively. The eco-landscape forest already had a high ability to control the environment. The community structure of the eco-landscape forest performed relatively stable. Furthermore,the eco-landscape forests helped to form regional distinctive characters of landscape architecture,and enriched the urban landscape resources. The ecological function of the eco-landscape forest could be reflected by the values of carbon sequestration,removal of harmful gases,and effective closure of storm runoff (8050407,271164,18468438 yuan). The eco-landscape forest plays an important role in improving and maintaining the ecological environment in downtown of Hefei.
