This paper deals with status of eight heavy metals (Hg, Cd, Pb, As, Cu, Cr, Ni and Zn) in the soil from the Fengrun region, Tangshan City, Hebei province and quality evaluation of the soil. The result of the investigation indicates that: 1. the study area soil is neutral — alkaline — strongly alkaline;2. the organic matter content is widespread low;3. high concentrations of all heavy metals distribute in the localities where there are intensive mankind's activities. The most outstanding localities are Xiaodaodi village, Shawoxin village, Puzhuangzi village, Qianxinzhuang village, Xuezhuang village and Hancheng town. The main pollutant exhausting enterprises in study area are Guofurunxing Milk Ltd., the hennery, Jinxiang chemical fibre factory, Tangshan Fuming steel Ltd.

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。
