摘要
通过对大熊猫主食竹产地华蓥山岩溶区土壤重金属元素As、Cd、Cr、Hg、Pb和Cu的调查分析,采用单因子污染指数法、综合污染指数法和相关性分析法对当地的土壤重金属环境质量进行了评价。结果表明,研究区6种重金属的单因子污染指数均小于0.7,综合污染指数也均小于0.7。土壤重金属中Hg与pH值、As之间存在显著正相关作用,Pb与Cu之间存在显著正相关作用,As与Pb、Cr之间存在显著负相关作用。华蓥山岩溶区土壤环境处于清洁无污染状态,给大熊猫主食竹的生长发育提供了保障,也有利于未来在此地的大熊猫放归。
Based on the investigation and analysis of heavy metal elements As,Cd,Cr,Hg,Pb and Cu in the soil of the Huaying Mountain karst areas where Giant panda's staple food bamboo is produced,the environmental quality of local soil heavy metals in the local soil was evaluated by single pollution index method,comprehensive pollution index method and correlation analysis method.The results showed that:(1)The single factor pollution index of the six heavy metals in the study area was less than 0.7,and the comprehensive pollution index was also less than 0.7.(2)There was a significant positive correlation between Hg and pH value,Hg and As,a significant positive correlation between Pb and Cu,and a significant negative correlation between As and Pb,As and Cr.The soil environment in the karst area of the Huaying Mountain is clean and free of pollution,which provides a guarantee for the growth and development of bamboo,the staple food of Giant pandas,and is also conducive to the future release of Giant pandas here.
