表土剥离对土地整治项目收益的影响研究

Study on Impact of Surface Soil Stripping to Land Remediation Projects

为了揭示表土剥离对土地整治项目收益的不同影响,作者采用采样分析、调查问卷、地统计分析、空间分析等方法对这种影响进行了分析。研究表明,表土剥离是土地整治工程必不可少的一步。通过土壤质量空间分布和作物投入—产出值比较分析,土地整治可有效减少农业生产成本,而表土剥离可最大限度地保护土壤表层,通过追肥和田间管理,在2—3年时间可基本恢复耕地肥力。

The objective was to reveal the surface soil stripping which had a significant impact on land remediation projects of income. The methods were sampling and analysis, surveys, geostatistical analysis, spatial analysis. The results showed that the surface soil stripping had obvious impact on land remediation projects. Though analysis the spatial distribution of soil quality and crop inputs,land remediation could effectively reduce the cost of agricultural production, and topsoil stripping could maximize the protection of the soil surface, arable land fertility could be recovered in 2 - 3 years by topdressing and field management.
