【摘要】 试验模拟了冻土及融土中生活垃圾的填埋对于周边土体的影响,通过检测填埋场各点处土壤含水量、温度、含盐量和有机质的含量,认为水分运移是影响可溶盐离子迁移的主要因素,盐分与水分的分布具有很好的一致性;温度对盐离子的迁移及有机质的分解有很大影响,温度越高,盐离子的迁移及有机质的分解速率越快。冻土环境不利于可溶盐离子及有机质的迁移与分解,冻土中各点含盐量及有机质含量高于融土。更多还原

【Abstract】 The experiment simulated municipal waste landfill in permafrost and unfrozen soils and its influence on surrounding soils. Through detecting water content, temperature, salt content and organic content in different sites of landfill area, it was found that water transport is the main factor in affecting soluble salt ions and there is very good consistency between water movement and salt ions movement. Temperature has a great influence on transport speed of salt ions and decomposition speed of organic matters, the higher the temperature, the faster the speed. Permafrost environment is not favorable for salt ions transport and organic decomposition, and the salt content and organic matter content in permafrost is higher than that in unfrozen soils.更多还原
