摘要
为了探讨高尔球场草坪养护对土壤重金属含量的影响,以海口北部地区东山球场和南洋河球场为研究靶区,分析球场20～40 cm土壤重金属Cr、As、Cd、Hg、Pb含量的水平差异。结果表明,(1)东山球场土壤重金属元素Cr、Pb和南洋河球场土壤重金属元素Cd、Hg的含量均存在显著差异(p<0.05);(2)与国家Ⅱ级标准值对比,东山高尔夫球场犁底层中的重金属元素Cd、Hg、Pb的含量出现超标现象,同时南洋河球场犁底层的中重金属Cd、Hg的含量也超标。且与外围背景值对比,两个球场犁底层的重金属呈现富集现象;(3)除发球台犁底层的Cd、Cr外,东山球场球道及果岭犁底层Cd、Cr、As、Hg、Pb的含量高于南洋河球场;东山球场发球台犁底层As、Hg、Pb的含量也高于南洋河球场;(4)球场草坪犁底层土壤中重金属元素含量高低,受经营时间和草坪养护时施用化肥品质的影响。
To investigate the impact of lawn maintenance on heavy metal contents in soil on golf course, Dongshan golf course and Nanyanghe golf course located at north of Haikou were selected as the research fields to analyze the spatial difference of five different heavy metals （Cr, As, Cd, Hg, Pb） in the depth of 20 - 40 cm soil. The results indicated that significant differences were observed in Cr and Pb contents on Dongshan golf course and Cd and Hg contents on Nanyanghe golf course （p〈0.05）. Compared with the national II standard value, Cd,Hg and Pb contents in the soil exceeded the standards on Dongshan Course, as well as Cd and Hg contents exceeded the standards on Nanyanghe golf course. But through the comparison of peripheral background values, heavy metal enrichment was observed on the two golf courses. The Cd, Cr, As, Hg and Pb content in the soil of Fairway and Green were higher on Dongshan golf course than Nanyanghe golf course expect for the Cd, Cr in Tee Ground. The As,Hg,Pb contents in the soil of Tee Ground were also higher on Dongshan golf course. The content of heavy metals in the plough pan soil was influenced by the management time and chemical fertilizer quality during the lawn maintenance.
