摘　　要：该文以莱芜市里辛土地整理项目为例,采用野外采样和室内分析相结合的方法,研究了丘陵区土地整理对土壤理化性状的影响。研究结果表明,土地整理对土壤物理性状影响极显著或显著;对土壤化学性状影响不显著;各土壤理化性状的变异系数,除土壤体积质量增加、土壤黏粒稍有增加外,其他均下降,整理后土壤理化性状更均匀。土壤理化性状变化原因主要是整理中注重物理措施、忽视土壤培肥,施工不规范及国家有关标准不具体等造成。今后应重视土壤培肥,规范施工,完善有关土地整理标准、明确各项土壤理化性状指标等,以确保土壤质量提高。Taking Lixin Land Consolidation Project of Laiwu City as an example, combining field survey with in-door analysis, effect of land consolidation on soil physical and chemical characteristics of hilly region were studied. The results indicated that effects of land consolidation on soil physical characteristics were highly significant or significant whereas on soil chemical characteristics were not significant yet. Except for soil bulk density increased and soil clay content slightly increased, other soil physical and chemical characteristics＇ coefficient of variations were decreased and soil physical and chemical characteristics was more uniform after land consolidation. The causes were paying attention to physical measures but ignoring improvement of soil fertility during land consolidation, non-standard construction, the State＇s relevant standards unspecific. Ensuring soil quality increased, improvement of soil fertility be taken into account and construction be standardized, relevant standards be perfected, and soil physical and chemical characteristics standards be materialized in the future.
