| 摘 要： | 以重庆南温泉公园为研究对象,将该公园的八大功能区(即主入口景观设施区、主入口花园区、草坪花园区、河川散步设施区、活动景观设施区、自然花园区、VILLA设施区、树木保全区)作为8个调查样点,分别记为LG1、LG2、LG3、LG4、LG5、LG6、LG7、LG8,分别调查了8个样点的土壤pH,以及土壤硼元素、铜元素、锌元素、铁元素的丰缺水平。结果表明:各区域土壤pH≥7.5,呈中性或碱性;有效铁、有效铜、有效锌含量较为丰富,而有效硼较为缺乏。并针对各区域实际情况,提出了对该地进行以土壤改良为基础的生态修复,以期为该植物园今后的植物配置、后期管理及土壤修复等提供借鉴。

| Abstract: | By taking Chongqing Nan Hot Spring Park as the research object,eight functional zones of the park has been selected as the survey sampling spots,covering main entrance landscape facility zone,main entrance garden zone,lawn garden zone,river walking facility zone,activity landscape facility zone,natural garden zone,VILLA facility zone,and trees protection zone which are recorded as LG1,LG2,LG3,LG4,LG5,LG6,LG7 and LG8,respectively.It has investigated pH,the content of boron,copper,zinc and available zinc in soils of the eight sampling spots.The results show that pH of the soil of each spot is equal to or larger than 7.5,which is neutral and alkaline;available iron,copper and zinc are abundant while available boron is insufficient.In view of the actual situation of each spot,it has proposed ecological restoration based on soil improvement,so as to provide a reference for plants disposition,later maintenance and soil restoration in the park in the future. |
