The subject of the paper is the greenbelt soils in the different functional areas in Xuzhou.The variational tendencies of greenbelt soils in 4 urban areas within the third rings were studied by analyzing the physicochemistry property and the nutrient status of the soil in these functional areas and comparing with the natural cinnamon soil in these functional areas.The results were as follows:The soil bulk density was higher,total porosity and field capacity of preserving water were small,organic materials were...

The subject of the paper is the greenbelt soils in the different functional areas in Xuzhou.The variational tendencies of greenbelt soils in 4 urban areas within the third rings were studied by analyzing the physicochemistry property and the nutrient status of the soil in these functional areas and comparing with the natural cinnamon soil in these functional areas.The results were as follows:The soil bulk density was higher,total porosity and field capacity of preserving water were small,organic materials were scant,the content of nutrients distributed uniformly,and the trend of pH value was upward.The order of excellence of physicochemistry properties in every area was productive plantation area>park square greenbelt>residential area greenbelt>road traffic greenbelt.

以徐州市不同功能区的绿地土壤为研究对象,通过对徐州市三环路内4个城区土壤的理化性质与养分状况等指标进行分析,并与该地区自然土壤进行了对比,研究其变化的趋势。结果表明:该城区绿地土壤的容重较大,孔隙度和田间持水量少,有机质缺乏,养分含量不均,pH值呈上升趋势。另外从绿地类型上加以比较、分析,其各样区土壤理化性质优劣顺序为:生产绿地〉公园广场绿地〉居民小区绿地〉道路交通绿地。

From May to October,2006,soil animal communities from 4 greenbelts in Baoding city were investigated,a total of 1049 soil animals were collected,belonging to 14 orders,8 classes,and 14 phyla.The dominant groups were Aconite,Collembola and Hymenoptera,while Tubificidae,Arenas,Isopoda,Diplura,Coleoptera larvae were the ordinary groups and others were rear groups.The composition of soil animals in 4 habitats was extremely similar.There was a change trend for the 4 kinds of land as follow: Nursery greenbelt > Park...

From May to October,2006,soil animal communities from 4 greenbelts in Baoding city were investigated,a total of 1049 soil animals were collected,belonging to 14 orders,8 classes,and 14 phyla.The dominant groups were Aconite,Collembola and Hymenoptera,while Tubificidae,Arenas,Isopoda,Diplura,Coleoptera larvae were the ordinary groups and others were rear groups.The composition of soil animals in 4 habitats was extremely similar.There was a change trend for the 4 kinds of land as follow: Nursery greenbelt > Park greenbelt > Road greenbelt > Defend greenbelt in the animals density in soil.From the vertical distribution of soil animals in soil profile,the total amount of soil animals tend to decrease gradually with the soil layer increase generally,and the highest was in the 0~5 cmhorizon,the soil animals showed obvious surface assembly phenomenon.The evenness and abundance index of soil animals are positively correlated,but the evenness and the dominance are negatively correlated.

2006年5~10月对保定市4种城市绿地生境中的土壤动物群落进行了调查研究,共采获到土壤动物1462只,隶属2门8纲14目。其中优势类群为蜱螨目、弹尾目和膜翅目,常见类群为颤蚓目、蜘蛛目、双尾目和鞘翅目幼虫,其余类群为稀有类群。4种绿地类型的土壤动物种类组成极为相似。从单位面积土壤动物数量看,表现为苗圃绿地>公园绿地>道路绿地>防护绿地。从土壤动物群落数量的垂直分布来看,随着土壤层次的加深而递减,0~5 cm土壤层数量最大,有明显的表聚现象。土壤动物的多样性与均匀度指数呈正相关,与优势度呈负相关。
