    摘要:

    为揭示上海城市公园不同建成时期木本植物种间关系的变化特征,选取分属4个时期(1995年前、1995―2004年、2005―2017年、2018年后)的14座城市公园,通过调查1 434个10 m×10 m的植物群落样方,针对重要值(IV)≥5的29种乔木和27种灌木,运用方差比率法(RV)、χ2检验和Spearman秩相关系数检验分析种间关联性。结果显示:各时期乔灌木总体关联性均呈显著正联结(RV>1,P<0.05),且随建成时间逐步增强,RV从时期Ⅰ的1.43升至时期Ⅳ的1.98。乔木层种间关系呈现明显差异,早期(时期Ⅰ)以不显著负联结为主,表现为树种习性差异;后期(时期Ⅳ)形成显著正关联,表现为生态位需求相似。灌木层始终保持强的正联结,时期Ⅳ的RV达1.98,Spearman秩检验正相关种对比例达23.81%。乔灌木层间正相关种对从时期Ⅰ的5.06%升至时期Ⅳ的5.98%,负相关种对占比减少,总体联结性持续增强。因此,建议早期建成公园应重点替换负关联乔木种对,新建公园需配置乔木层正关联组合,灌木层则强化适生树种集群配置,以提升植物群落稳定性。

    Abstract:

    14 urban parks belonging to four periods including before 1995 (periodⅠ), 1995-2004 (periodⅡ), 2005-2017 (periodⅢ), and after 2018 (periodⅣ) were used to study the changing characteristics of interspecific relationships of woody plants in urban parks in Shanghai City during different periods of construction. 1 434 plant community plots of 10 m×10 m were investigated. The variance ratio method (RV), chi-square (χ2) test and Spearman’s rank correlation coefficient test were used to analyze interspecific associations for 29 arbor species and 27 shrub species with an important value (IV)≥ 5. The results showed that the overall associations between arbors and shrubs in each period had a significantly positive correlation (RV>1,P<0.05), and gradually increased with the extension of construction time, with the RV increasing from 1.43 in periodⅠto 1.98 in periodⅣ. The interspecific relationships in the layer of arbors had significant differences, with insignificant negative associations being the main feature in the early period (periodⅠ),manifested as differences in habits of species. A significant positive correlation was formed in the later period (periodⅣ), manifested by similar demands of ecological niche. The layer of shrubs maintained strong positive association throughout all periods, with the RV reaching 1.98 in periodⅣ and the proportion of positively correlated pairs of species in the Spearman’s rank test accounting for 23.81%. The proportion of positively correlated pairs of species between the arbor and shrub layers increased from 5.06% in periodⅠto 5.98% in periodⅣ, while the proportion of negatively correlated pairs decreased, with a continuous enhancement of overall interspecific association. Thus, it is recommended that priority should be given to replacing arbor species with negative associations for renovation of parks in the early period. Newly constructed parks should be equipped with positive correlation combinations in the layer of arbor and the layer of shrub should be strengthened with clustered configuration of suitable native species to improve the stability of plant communities.
