摘要

摘要: 以上海市内悬铃木(Platanu sacerifolia)、香樟(Cinnamomum camphora)和水杉(Metasequoia glyptostroboides)所构成的~5~种植物群落为研究对象, 分析并比较 5 种植物群落的土壤理化性质和酶活性(蔗糖酶、脲酶和磷酸酶)季节动态的相关性. 结果表明, ① 总体上, 阔叶林土壤理化指标及土壤酶活性大于针叶林, 同时, 混交林土壤理化指标及土壤酶活性大于单种林; ② 各植物群落土壤理化指标及土壤蔗糖酶活性在秋季、冬季较高, 而脲酶和磷酸酶活性在春季较高; ③ 植物群落类型与季节交互作用对土壤理化性质无显著影响, 但对土壤酶活性影响显著; ④ 不同土壤酶之间、土壤酶活性与土壤理化性质之间均存在着不同程度的相关性. 研究结果表明, 混交复合群落应该成为今后城市绿地建设中主要的植物群落类型, 同时, 在城市绿地养护过程中应依据不同时期的土壤营养状况进行针对性管理.

Abstract: To explore and compare the correlation between the seasonal dynamics of soil physical and chemical properties and soil enzyme activities (sucarse, urease, phosphatase) in Shanghai green land, soil samples under five types different plant communities which consist of Platanu sacerifolia, Cinnamomum camphora and Metasequoia glyptostroboides were collected and analyzed. Results showed that: First, soil physical and chemical indicators and soil enzyme activities were much higher in broad-leaf forests and mixed forests than those in coniferous and single-dominant forests, respectively. In addition, soil physical and chemical indicators and soil enzyme activities were relative higher in both autumn and winter, and expect urease and phosphatase activities were higher inspring. Moreover, there were significant interactive effect of plant communities and seasons on soil enzyme activities, but not on soil physical and chemical indicators. On the whole, there were various degrees of correlations between different soil enzymes as well as between soil enzyme activities and soil physical and chemical properties. These results indicated that mixed forests should be the main plant community types in the construction of urban green land, and also the aimed management of soil nutrition status at different periods during the process of urban green land maintenance also should be taken much into account in the future.
