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.
