摘　　要：对保定市郊耕地、公园、城市公路绿化带、学校和生活区5种土地利用类型的土壤进行采样,实验分析了土壤的吸湿水、有机质、铵态氮、酸碱度、速效磷等理化指标.运用灰色综合评估对实验数据进行分析,结果表明,公园土壤性状灰评估得分最高,为88.28,耕地、生活区、学校和公路绿化带土壤性状灰评估得分分别为78.07、61.75、56.82和50.57,公路绿化带土壤性状最差.对评估结果进行分析,并针对不同土地利用类型土壤性状的改善提出合理化建议.Soil samples are collected from farmland,park,road greenbelt,school and living areas in Baoding. The hygro-scopic water,organic matter,nitrogen,p H,available phosphorus were tested in laboratory for the samples. The data were analyzed by using grey comprehensive evaluation. The results showed that the park soil evaluation score is 88.28,which is the highest among all samples. The evaluation scores of soil samples of farmland,living areas,school and road greenbelt are 78.07,61.75,56.82 and 50.57,respectively. The soil property of road greenbelt is the worst. The evaluation results are analyzed,and then some rational proposals are presented for improving soil properties of different land utilization types.
