摘要
选取了绿地景观构成、景观破碎度、景观多样性指数、景观最小距离指数、景观连接度指数和景观分维数等景观生态学指标对上海市建成区范围内的 77个公园进行景观格局分析。结果表明 ,上海城市公园绿地总体上趋于随机分布 ,公园平均连接水平较低 ;公园绿地中平均林地景观面积最大 ,其次是林灌草综合体景观 ,草地面积最小 ;林灌草综合体破碎化程度最高 ;草地景观次之 ,林地斑块破碎化程度最低 ;
Landscape pattern of 77 parks in Shanghai were analyzed after studying the structure of green space, the fragmentation index, the landscape diversity , the index of minimum distance, the connectivity of green space, and the landscape fractal dimension . The result show that the distributing of green land of park in Shanghai is random; the average of connectivity of park is lower; the average area of forest landscape is maximum, the mixed forest shrub grass landscape is secondary, the grass landscape is minimum; the degree of fragmentation patches of the mixed forest shrub grass landscape is maximum, the grass landscape is secondary, and the forest landscape is minimum; the landscape fractal dimension is low in all parks.
