摘 要: | 在潞安矿务局五阳煤矿采煤塌陷地上,按照混推和剥离两种复垦方法,分复垦种植1年、3年和5年进行采样,对不同复垦方法及年限下土壤养分、重金属元素含量以及物理性质进行分析,得出了不同复垦方法及年限对土壤肥力及其变化规律的影响,为制订科学合理的土地复垦标准提供依据。

A Study on Soil Fertility Change with Different Reclamation Methods and Years of Subsiding Mined Land |
| |
Abstract: | Through sampling different kinds of the reclaimed subsiding land in Wuyang coal mine, Luan corporation, which have respectively been reclaimed for 1, 3 and 5 years by topsoil stripping and unstriping methods and analyzing the soil fertility, heavy metal content and physical properties of each sample, the author reached a conclusion of different reclamation methods and different reclamation years affecting soil fertility and its regularity. This will provide the basis for reasonably and scientifically working out land reclamation standards. |
