摘要
This paper tests and analyses the contents of 5 heavy metal elements (As, Cd, Pb, Hg, Cr) in the Siraitia grosvenorii and the A layer soil on 8 different formations in the north region of Guilin City.The results are as follows.The pollution level of the A layer of soil shows medium or above.The main pollution elements are Pb,Cr,and As.The content of 5 heavy metal elements in the Siraitia grosvenorii are far lower than the national green industry standard value,indicating that the Siraitia grosvenorii is characterized by anti-pollution and high quality in the karst-ecological region.Thus,the development of resource plant——Siraitia grosvenorii should be strengthened.
