山东省黄河下游流域生态地球化学调查主要成果

Major Achievements Gained in Ecological and Geochemical Survey in the Lower Reach of the Yellow River in Shandong Province

摘要:

农业地质环境调查成果表明，山东省黄河下游流域5.4万km2的土地质量总体状况良好，绝大多数土地是清洁的。调查区内有99.9％的土壤为绿色土壤，可生产无公害小麦、玉米等农产品；一类土壤占92.7%，适宜于发展绿色食品生产；二类土壤占7.2%；三类土壤占0.1%。本次调查发现的重金属严重污染土地集中分布在城市的周边地区。浅层地下水地球化学调查结果表明，区内浅层地下水环境污染状况严重，水质优良的地段主要分布在济宁市区北、平阴周边、长清南、济南市区南部等靠近山前地段，其他平原地区的水环境质量多为较差或极差级（不
