摘  要:
由于长期的开发以及掠夺式经营,土壤退化和环境污染问题日益严重,黑土区环境面临着较大的压力。尽管如此,我国对黑土区的研究尤其是区域尺度的关于黑土区农业环境地球化学质量的问题的研究重视不够,相关的研究不多。本文采用GIS和AHP藕合的方法对黑龙江省中部黑土区农业地球化学环境质量进行综合评价。研究表明:黑土区农业地球化学环境非常优越,优越区和适宜区面积共占黑土区总面积的88.06%;较不宜区和不宜区面积总共仅占黑土区面积的8.35%。不宜区主要分布在坡度较大的(一般>25°)和黑土区重金属含量较高的一些污染地区以及植物必需微量元素含量缺乏的地区。

摘  要:
The black soil region is important food base of China,it plays an important role in food safety and national economy.But there are few studies on environmental capacity's spatial characteristic of black soil.The regional agriculture geochemistry environment quality integrated estimation of black soil region was finished by applying the method of AHP and GIS,this providing scientific data for precise agriculture practice and the sustainable development in the area of black soil region.The study results show that the black soil region has predominant agriculture geochemistry environment.Predominant area and fitting area account for 88.06% of the black soil region.Relatively unfavorable and unfavorable areas account for 8.35%.Unfavorable region is mainly distributed in the high slope region(slope>25°) and polluted area with high heavy metal content and the area shortage of plant indispensable trace elements.
