摘要
本研究以盐城市为例,选取斑块密度、多样性指数、均匀性指数等指标对中心城区公园绿地景观格局进行分析。结果表明:(1)中心城区公园绿地斑块类型分布不均衡,面积大小差异大,小型斑块较多。(2)大中型和小型公园绿地斑块面积在不同区划范围存在显著差异。(3)公园绿地总体破碎化严重、景观多样性较低、景观丰富度上差异较大,其中亭湖区丰富度较高,其他三区多样性、均匀度相当。
In this paper, a case study was made in Yangcheng City and an analysis was made on the landscape pattern of central urban park greenbelt using such selected indexes as patch density, diversity index and evenness index. The results showed that:1. the distribution of patch types of the greenbelt was uneven with significant differences in area and more small patches;2. there were significant differences in the patch areas of large, medium and small-sized parks among different districts;3. in the park greenbelt,there existed serious general fragmentation, low landscape diversity and significant differences in landscape richness with highest richness in Tinghu District and even diversity and evenness in the other 3 districts.
