摘　　要：济南中山公园古树群是济南十大古树群之一,古树品种以清代侧柏(Platycladus orientalis(L.)Franco)为主。作为服务于城市的公园,古树受游人影响与城市环境变化等生境问题影响巨大。以济南中山公园53株古侧柏为研究对象,采取实地调研法、实验检测与信息归纳的方法,分析园内不同区域古树立地土壤理化性质。最终实验显示园内土壤含水量均值达19.33%,容重均值1.38,空隙度0.48,土壤物理性质粘重。土壤整体呈弱碱性,各养分含量均达到一般标准,S1、S2、S5研究区碱解氮和有机磷含量过高,易造成古树根部的损失,整体古树群呈衰退状态。结合古侧柏树生物形态现状分析树群健康状态,提出有针对性的古树复壮养护建议,有利于济南地区古树名木保护工作的深化,进一步完善现代古树名木复壮养护体系。The old tree group in Jinan Zhongshan Park is one of the top ten old tree groups in Jinan.The old tree species are mainly arborvitae in the Qing Dynasty.As a park serving the city,old trees are greatly affected by habitat problems such as the influence of tourists and changes in the urban environment.Taking 53 oldoriental arborvitae in Jinan Zhongshan Park as the research object,the soil physicochemical properties of old planting sites in different areas of the park were analyzed by means of on-the-spot investigation,experimental detection and information induction.The final experiment showed that the average soil moisture content in the garden was 19.33%,the average bulk density was 1.38,the porosity was 0.48,and the soil physical properties were sticky and heavy.The soil is weakly alkaline as a whole,and the content of each nutrient reaches the general standard.The content of alkali-hydrolyzed nitrogen and organic phosphorus in the S1,S2,and S5 study areas is too high,which is easy to cause the loss of old tree roots,and the overall old tree group is in a state of decline.Combined with the status quo of old tree biomorphology,put forward targeted old tree restoration and maintenance suggestions, which is conducive to deepening the protection of old and famous trees in Jinan, and further improving the modern old and famous tree restoration and maintenance system.
