摘    要:对沈阳城区绿地生态系统景观结构和异质性进行了分析。结果表明,沈阳城区绿地景观斑块以街头绿地斑块最多,占城区绿地块数的50%以上,但绿地面积只占4.45%,斑块大小以防护绿地和公园绿地斑块平均值最大,分别为66.97hm^2和59.21hm^2。而街头绿地和游园绿地斑块平均值最小,为0.71hm^2和0.38hm^2。景观多样性指数以街头绿地最高,而公园绿地最低,在沈阳城区的7个区中不同绿地类型中的优势度和均匀度都比较小,但斑块绿地优势度高于廊道绿地的10倍多,绿地分布不均衡,应增加绿地斑块数量,均匀配置公共绿地(公园绿地、道路绿地),增加绿色廊道,建立城区与城郊自然生态系统绿色通道和充分发挥沈阳城区3条人工运河带状绿地美化环境、泄洪排涝和调节气候功能作用。

关 键 词:景观结构  景观异质性  绿地系统  沈阳

Abstract:Studies on the structure and heterogeneity of urban vegetation landscape in Shenyang city showed that the most vegetation patches were in the street corner,accounted for more than 50% of the total vegetation patch,and their area was only 4.45% of the total vegetation area. In terms of the size of the patches,the average area of shelter vegetation and park vegetation was 66.97 hm 2 and 59.31 hm 2,respectively,while that of street corner vegetation and garden vegetation was 0.71 hm 2 and 0.38 hm 2,respectively. Street corner vegetation had the highest index of landscape diversity,while park vegetation had the lowest one. In the seven districts of Shenyang city,all types of vegetation had a small landscape dominance and evenness,but patch vegetation had a more than 10 times of landscape dominance than corridor vegetation,indicating that there was somewhat imbalance in the allocation of different vegetation patch types. It's suggested that the quantity of patch vegetation should be increased,and the public vegetation should be distributed evenly. Increasing vegetation corridor is also important because it can link the downtown area to the suburb natural vegetation ecosystems. For example,the South Canal Belt Park of Shenyang is a good vegetation corridor,which can beautify Shenyang city,discharge sewage,drain flood,and improve microclimate.
Keywords:Landscape structure  Landscape heterogeneity  Vegetation  Shenyang
