| 摘 要： | 以大连市单位附属绿地、公共绿地、住宅区绿地、道路绿地4种典型城市绿地类型8个取样点的表层土壤为研究对象,采用野外土样采集和室内分析相结合的研究方法,就大连市城区不同绿地类型表层土壤大量元素、微量元素及重金属元素的分异特征进行系统研究.结果表明:大连市园林绿地土壤在养分特征上具有明显的空间变异性,但土壤化学元素多呈无规律分布.

| Abstract: | By using the surface soil from 8 sampling points of in four typical greenbelt in Dalian city, namely attached green space, public green space, residential green space and road green space, this study compares samples from field soil and laborato-ry analysis to study the spatial differentiation characteristics of the Macro-nutrient elements, trace elements and heavy mental el-ements in the surface soil of different types of green space in Dalian city. The results show that:Dalian city garden green land on the nutrient characteristics has obvious spatial variability, but the soil chemical elements distribution is irregular. |
