Abstract:

In this paper, 20 soil samples were collected from plow layers and plow pans of fairways, tee grounds, and putting greens on a golf course, respectively. In addition, the vertical and horizontal distribution of the contents of Cr, Ni, As, Cd, Hg, Pb, and Cu were analyzed at different soil depths in three types of turf areas. Heavy metal contents in other places basically satisfied the trend of plow pan>plough layer. Heavy metal contents in other places basically followed the trend of plow pan>plough layer, except for As and Hg in fairway soil and Cd in putting green soil. A comparison was conducted on the soil heavy metal contents in the plow layers and plow pans of fairway, tee ground, and putting green, and no significant difference was observed. However, in terms of the average contents of heavy metals in two depths, the average contents of Cd, Pb, and Cu showed an order of fairway > tee ground > putting green; the average contents of Hg and Ni showed an order of tee ground > fairway > putting green. For the average contents of Cr and As, the order was putting green > fairway > tee ground and fairway > putting green > tee ground, respectively. The contents of As and Pb in the turf soil on the golf course did not exceed the national standard limit, but were higher than the background values. The Cd and Hg contents and the Cr contents in the fairway plow pan and plow layer of the putting green exceeded both the national standard limit and the background values, and therefore presented a serious enrichment problem. The vertical distribution of soil heavy metals in the turf soil on the golf course was mainly influenced by the quantity of chemical fertilizers applied and rainfall, whereas the soil heavy metal contents of different turfs on the golf course were determined mainly by the quality of fertilizers applied.

摘要：

为探讨高尔球场草坪养护对土壤重金属含量的影响。系统采集了球场中球道、发球台、果岭耕作层及犁底层的土壤共20个样品，分析了三种草坪不同深度土壤中Cr，Ni，As，Cd，Hg，Pb，Cu的垂直含量和水平含量。结果显示：研究区域内，除了球道土壤中的As、Hg及果岭土壤中的Cd之外，其他地点的重金属基本上都是犁底层>耕作层。球道、发球台、果岭的耕作层及犁底层重金属含量无显著差异。但从两个深度重金属的平均含量看，Cd，Pb，Cu的平均含量呈现球道 > 发球台 > 果岭；Hg，Ni的平均含量呈现发球台 > 球道 > 果岭；Cr的平均含量呈现果岭 > 球道 > 发球台；As的平均含量呈现球道 > 果岭 > 发球台。高尔夫球场草坪土壤中As、Pb两种重金属含量未超国家标准限值，但高出背景值。Cd，Hg及球道犁底层、果岭耕作层的Cr含量既超过国家标准限值又超过背景值，富集严重。球场草坪土壤中重金属的垂直分布主要受施用化肥及降雨量的影响，而不同草坪土壤重金属的含量则与球场施用化肥的品质有关。
