Evaluation of Soil Environmental Quality in Lycium barbarum L.Producing Area in Zhongning County
摘要
Abstract
To explore the soil environmental quality status and the spatial distribution characteristics of heavy metal elements in the Lycium barbarum production area of Zhongning County,Ningxia,198 soil samples were collected from the Lycium barbarum production area of Zhongning County from June to October 2020.9 physical and chemical indicators and the contents of 8 heavy metal elements in the soil samples were determined.The research results showed that the surface soil of the Lycium barbarum production area in Zhongning County was all alkaline.The coefficient of variation of available phosphorus,total salt,total phosphorus and alkali-hydrolyzable nitrogen in the soil was relatively large.The contents of organic matter,total nitrogen and alkali-hydrolyzable nitrogen were relatively low.More than 50%of the soil was in a state of deficiency to extreme deficiency.The evaluation results of heavy metal pollution in the soil of Zhongning County showed that the overall quality of the soil in the Lycium barbarum production area of Zhongning County was relatively good.Heavy metal elements in the soil showed a relatively obvious spatial distribution pattern,which was the same as that of organic matter and opposite to the pH value.The high-value areas of heavy metal distribution were all located in the northwest of Zhongning County(the northwest of Zouta Township,Ning'an Town,Xinbao Town and Enhe Town),while the low-value areas were in the southeast of Zhongning County(the southeast of Dazhanchang Town,Mingsha Town,Xinbao Town and Enhe Town).The heavy metal elements in the surface soil were jointly affected by natural and human factors,especially the Hg and Pb elements in the soil were greatly affected by human activities.关键词
