摘要: |
城市荒野作为城市生态系统中最为自然的一部分, 其形式多样、 生境类型繁多, 夹缝便是其中
的一个微型生境种类。 为更好地挖掘城市荒野的潜能、 实现生态文明建设, 研究以安徽省合肥市和广东省
广州市的夹缝植物为例, 通过对两地夹缝植物的秩多度曲线陡度、 多样性、 均匀性和相似度系数进行计
算, 得出结论: (1) 合肥市和广州市夹缝植物的种-科、 种-属和属-科的秩多度曲线均呈反 J 型, 均符合
倒数模型; (2) 合肥市夹缝植物的科、 属、 种之间分布不均匀, 且与广州市夹缝植物的科、 属、 种之间
分布的均匀性相差较大; (3) 两地夹缝植物的科类相似, 但属和种的相似度较低, 且物种差异性较大。 |

Abstract: |
Urban wilderness, the most natural part of urban ecosystems, is characterized by diverse forms
and habitat types, in which crevice is one of the microhabitat types. In order to better explore the potential of urban wilderness and realize the construction of ecological civilization, the steepness, diversity, homogeneity,
and similarity coefficients of the rank multiplicity curves of crevice plants in Hefei city, Anhui province and
Guangzhou city, Guangdong province were detected in this study. The results suggested that: (1) the rankmultiplicity curves of the crevice plants in Hefei city and Guangzhou city were both displayed as inverse J-type, and conformed to the inverse model; (2) the distribution of families, genera and species of crevice plants in
Hefei city was not uniform, which was different from that of Guangzhou city; (3) the crevice plants in the two
cities demonstrated relatively high similarity in the families, but low similarity in genera and species. |
