Abstract:
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.
