沈阳城市绿地系统的景观生态评价

Landscape ecological evaluation of urban greenland system in Shenyang

运用景观生态学原理和方法,选取多样性指数、均匀度指数、破碎度指数、分离度指数、分维度指数、连通性指数等8个景观格局指数对沈阳市城市绿地系统的景观格局进行分析。结果表明:沈阳城市绿地景观总体表现为绿地率较低,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,景观类型较齐全,均匀度较低,景观分离度较小。针对存在的问题,提出了沈阳城市绿地景观生态规划建议。

Based on the landscape ecological principles and methods, and using eight landscape pattern indices （landscape diversity index, evenness degree index, separation index, isolation index, fractal dimension index, and connectivity index, etc.）, this paper analyzed the urban greenland landscape pattern in Shenyang. Overall, the green space had a lower proportion, its distribution was disproportional, and the structure of greenland system wasn’t reasonable. The separation index was high, the fractal dimension was low, the landscape types were rather complete, the evenness degree was low, and the isolation index was small. Aiming at these problems, some suggestions on the ecological planning of urban greenland landscape in Shenyang were put forward.
