- 摘要:
- 公园绿地是城市绿地的重要组成部分,为研究公园草坪土壤钙素分布特征,以长春市公园草坪土壤为研究对象,测定研究区域内7个公园草坪土壤的全钙、交换性钙、酸溶性钙、有机质含量、土壤酸碱度(pH),分析城市公园草坪土壤钙素垂直分布特征及其相关性。结果表明:1)城市公园草坪土壤中全钙、交换性钙及酸溶性钙的含量伴随土层加深呈增长趋势;2)土壤全钙与交换性钙、酸溶性钙在各土层均表现为显著相关(P<0.05);3)土层土壤pH伴随土层加深呈逐渐减少趋势,与土壤全钙、酸溶性钙、交换性钙含量呈负相关关系;4)土壤有机质含量伴随土层加深呈逐渐减少趋势,与土壤全钙、酸溶性钙、交换性钙含量呈正相关关系。分析城市公园草坪土壤发育与肥力的状况,可以揭示在城市化进程中城市公园草坪绿地土壤钙含量的分布特点,从而为公园自然绿地的保护和人工绿地的管理提供参考依据。
- Abstract:
- Park green space is an important part of urban green space.In order to study the distribution characteristics of soil calcium in park lawn,taking the soil of city park lawn as the research object,the total calcium,exchange calcium,acid-soluble calcium,organic matter content,soil pH of 7 park lawn soils in the research area were determined,and the vertical distribution characteristics and correlation of calcium in the soil of urban park lawn were analyzed.The results showed that,1) The content of total calcium,exchange calcium and acid soluble calcium in the soil of urban park lawn was increasing with the deepening of soil layer.2) Soil total calcium was significantly correlated with soil exchange calcium and acid-soluble calcium in each soil layer(P<0.05).3) The pH of soil layer was gradually decreasing along with the deepening of soil layer,and the content of soil calcium,acid-soluble calcium,and exchangeable calcium was negatively related.4) The content of soil organic matter was gradually reduced along with the deepening of soil layer,and was positively related to the content of soil calcium,acid-soluble calcium,and exchangeable calcium.By analyzing the soil development and fertility of urban park lawn,we could reveal the distribution characteristics of soil calcium content in urban park lawn,thus providing reference for the protection of natural green space and the management of artificial green space.
