遵义地区农产品产地重金属安全预警判定模型

Heavy Metal Judging Model Security Warning of Agricultural Products in Zunyi

本文以遵义县农产品产地作为研究对象，建立农产品产地安全长期预警模型，分析遵义县粮食产地污染现状，进行环境恶化状态预警。突破性的采用了改进AHP加权平均综合指数法对遵义地区农产品产地的环境综合污染指数进行判定，对土壤重金属污染最严重的5种金属镉（Cd）、铅（Pb）、砷（As）、汞（Hg）、铬（Cr）进行了权重的判定，ωi=（0．2649，0．0770，0．0770，0．4193，0．1618），建立预警判定模型，计算出2008年遵义地区综合污染指数为Y2008=0．524，表明贵州省遵义地区农产品产地很清洁，不用进行环境恶化状态预警。

This paper takes Zunyi County of place of origin of agricultural products as the research object, es-tablishment of places of origin of agricultural products safety in long term prediction model, Analysis of the Zunyi County food source pollution, Environmental deterioration warning. Breakthrough by Improved AHP weighted composite index method District of Zunyi agricultural environmental pollution comprehensive index determination. On the soil heavy metal pollution is the most serious of the 5 metals Cd, Pb, As, Hg, Cr were weight determination, ωi= （0. 2649,0. 0770,0. 0770,0. 4193,0. 1618 ） , The establishment of early warning decision model, Calculated from the 2008 Zunyi area comprehensive pollution index of Y2008 = 0. 524. That region agricultural production in Zunyi is very clean without environmental deterioration warning.
