河南省主要城市土壤污染评价及防护措施

Soil Contamination Assessment of Main Cities in Henan Province and Its Protection Measures

从土壤污染概念入手,介绍了土壤污染造成的危害,阐述了土壤污染评价的原则和方法。通过单指数评价和多指数综合评价方法得到河南省10个地级市的土壤污染现状,结果中列举出主要污染因子并剖析其污染原因,着重总结了污染分布地区及污染程度。分析结论认为,河南省主要城市土壤污染程度不大,但是工农业活动频繁的部分区域已达到中重度污染,需要引起重视并进行治理,未污染及轻度污染地区也应采取措施防止范围扩大。最后提出相应的防护措施。

Soil quality has a direct impact on crop growth and people＇s health. Henan province is a large province for grain-produced and population in China, so it is significant to assess its soil quality. We introduced the harms by soil contamination, described the principles and methods of soil contamination assessment. Its current situation of ten municipal cities in Henan Province was obtained by single index and multi-index comprehensive evaluation methods, the main pollution factors were enumerated and the causes of pollution were analyzed, the pollution areas and degree were emphatically summarized： soil pollution degree was not high in main cities of Henan, but the degree had reached middle and serious in the areas with frequent industrial and agricultural activities, so more attention should be paid on these areas; in non-pollution and light pollution areas measures should also be taken to control pollution range. Finally the corresponding protection measures were proposed.
