南京城市绿地景观格局之初步分析

运用景观生态学原理,选取了绿地景观构成、景观破碎度、景观分离度、景观分维数等景观生态学指标对南京市主城区范围内的城市绿地进行了景观格局分析.结果表明,南京城市绿地景观总体表现为绿地斑块分布不均衡,景观结构不合理,破碎度较高,分维数较低,综合评价得出,绿地景观格局较好的有玄武区和建邺区.最后针对南京市绿地建设中存在的一些问题并提出了相应的建议,研究结果有助于南京城市绿地建设更进一步的完善.

Analysis on the Pattern of Urban Green Land Features in Nanjing

Based on the landscape ecological methods, the paper analyzes the urban greening landscape pattern using the structure of green space, the landscape fragmentation, the landscape isolation and the landscape fractal dimension. The result shows that the distribution is disproportional and the structure of green land in Nanjing isn't reasonable; the fragmentation index is higher and the landscape fractal dimension is less. Fuzzy comprehensive assessment method was used to evaluate greenbelt landscape with indices of urban greenbelt landscape structure. The results indicated that the greenbelt landscape in Xuanwu district and Jianye district were more desirable. The ecological problems of the urban greening landscape of Nanjing were analysed and corresponding strategies were put forward. The aim of this paper was to help make the landscaping of Nanjing city more perfect.
