徐州新城区绿化土壤适宜性分区研究

Study on the Suitability Zoning of Greening Soil in Xuzhou New District

城区绿化栽种植物种类多,相对区域较小,利用灰色聚类法把预种植物分配到土壤相对适宜的区域是一种较为可行的方法。在聚类分区中利用各级线性地物划分聚类对象,并对种类繁多的植物简要分类十分重要。应用该方法对徐州新城区大龙湖周边土壤适宜性进行了分区。

There are a lot of floristic species at urban afforesting and greening in a relative smaller area. Gray clustering is a feasible method to assign these floristics to their suitable area, in which assorting vegetable and delineating the clustering objects by linear features are necessary. This method was used in soil suitability .zoning in the surrounding area of Dalong Lake of Xuztxm New District.
