The total and available contents of micronutrients(Zn,Mn,Cu and Fe)in the black soils(Udic Isohumosols)in Gongzhuling,Hailun and Beian were determined and evaluated.The results showed that the total contents of Zn,Mn,Cu and Fe were little changed compared with the results obtained in1980.The available contents of the four micronutrients were higher than the correspondent critical values of shortage,which means that there were no defects of these micronutrients in the3areas.Except the available Cu in Beian...

以不同地区黑土阳离子微量元素的全量及有效态含量变化为研究内容 ,重点讨论和评价了锌、锰、铜和铁的分布状况、变化规律和丰缺程度。研究结果表明 :公主岭、海伦和北安地区黑土全锌、全锰、全铜和全铁平均含量与1980年第二次土壤普查结果基本一致 ;有效锌、有效锰、有效铜和有效铁的平均含量都高于缺素的临界值 ,说明3个地区黑土中目前不会出现严重的微量元素缺乏的现象。除北安地区有效铜含量低于1980年第二次土壤普查结果外 ,其他地区微量元素有效含量都有所提高 ,一般顺序为 ,公主岭<海伦<北安。黑土中微量元素与其他理化形状之间的相关性在不同地区表现不同 ,但有效锌、有效铜和有效铁含量与黑土中有机质含量之间存在一定的正相关。因此 ,在目前情况下 ,黑土中有机质水平可以基本上反映出微量元素的丰缺程度。

The black soil region is important food base of China, it plays a great role in food safety and national economy. But there are few studies of regional geochemistry spatial characteristic of black soil. In this article we study the geochemistry spatial characteristic of black soil region of Heilongjiang province based on GIS. It shows that most trace elements is proper high in black soil region .But some heavy elements such as Pb show regional pollution. On the other hand some compulsory elements of plant such as Zn, Mo show insufficiency which should be pay more attention to. 

黑土区向来是我国重要的商品粮生产基地,对于我国的粮食安全和国民经济的稳定都有着举足轻重的作用。但是大范围的关于黑土环境地球化学特征的研究却很少,本文主要利用黑龙江省1:50万区域化探资料应用GIS分析了黑龙江省黑土区环境地球化学空间特征。研究得出:黑土区大部分微量元素的含量还是比较高的,但是某些重金属元素如Pb等出现多个高值,反映了污染范围广而分散的特点;某些植物必需微量元素如Zn、Mo显现出不足的趋势,这对本区的可持续发展是不利的,应当予以重视。

The black soil region is the important food base of China,It plays a great role in food security and national economy.But there are few studies of regional geochemistry spatial characteristic of the black soil region.By selecting five heavy metal elements,the geochemistry environmental quality of the black soil region in Heilongjiang province is evaluated based on GIS.The result shows that the geochemistry environment of the black soil region in Heilongjiang province is good.There is no pollution...

The black soil region is the important food base of China,It plays a great role in food security and national economy.But there are few studies of regional geochemistry spatial characteristic of the black soil region.By selecting five heavy metal elements,the geochemistry environmental quality of the black soil region in Heilongjiang province is evaluated based on GIS.The result shows that the geochemistry environment of the black soil region in Heilongjiang province is good.There is no pollution in most part of the region.In some part of northwest region there is slight pollution.Only near Bin and Bayan county shows moderate pollution.

黑土区向来是我国重要的商品粮生产基地 ,对于我国的粮食安全和国民经济的稳定都有着举足轻重的作用。但是大范围的关于黑土区环境地球化学特征的研究却很少 ,本文主要利用黑龙江省 1∶ 5 0万区域化探资料 ,选取五种重金属元素在 GIS支持下对黑龙江省黑土区环境地球化学质量进行了评价 ,评价结果表明 ,本区的地球化学环境质量是比较好的 ,大部分地区处于无污染的水平 ,只是在西北部的克山和克东一些地区处于轻度污染的水平 ;中度污染只出现在宾县和巴彦交接处附近的极小部分地区
