根据无公害食品产地环境要求，本文对绵竹市新开村的土壤的中重金属含量以及土壤p H值进行了检测．研究结果表明：新开村的土壤重金属综合污染指数为1．48，处于轻度污染．土壤重金属综合累积指数为5．5，富集程度较强．其中，Cd的单项污染指数为1．97，属于轻度污染．土壤C d和H g的累积指数分别达到7．47和3．44，呈现强烈富集，可能与地震前的工业活动或人为活动有关．Zn的累积指数为1．38，表现为一定的污染，但程度较轻；Pb、Cr、N i、C u和A s的累积指数分别为1．11、0．96、1．09、1．04、0．81，与背景值较接近．据此检测结果，作者提出当地农业产业规划制定时应注意重金属污染的治理问题，并给予了针对性的发展建议．

According to the green food production requirement ,this article investigates the pH value and heavy metal content of the soil of Xinkai Village ,Mianyang City .The result indicates that the composite pollution index of heavy metal is 1 .48 ,which is considered as light pollution .The cumulated index of heavy metal is 5 .5 ,which shows a relatively large degree of accumulation .The single pollution index of Cd in soil reaches 1 .97 ,and it is among the lightly polluted range .Cumulative index of Cd and Hg re-spectively reach 7 .47 and 3 .44 ,showing a strong enrichment ,and it may be the result of industrial ac-tivities and human activities before the earthquake .The cumulative index of Zn is 1 .38 ,showing weak enrichment .T he cumulative index of Pb ,Cr ,Ni and Cu respectively reach 1 .11 ,0 .96 ,1 .09 ,and 1 .04 , which are close to the background values .The aim of this article is to provide several proposals for deal-ing with the pollution of heavy metal in local agricultural planning .By analyzing the results ,some coun-termeasures are proposed .
