摘要：

【研究目的】拟了解黄土丘陵土地整理区的土壤压实情况，从而制定相应的改良措施，促进土地资源的优化配置和有效利用。【研究方法】以闻喜县后宫乡的土地整理项目为研究对象，调查了压实地土壤的容重、紧实度、含水量以及渗水速率。【研究结果】结果表明：（1）与一般农田土壤相比，整理区土壤容重平均增高1.34倍、紧实度平均高484倍。（2）压实土壤的初始渗透速率为1.21mm/10min，稳渗速率为0.7 mm/10min，约相当于一般农田土壤的16%和28%。【研究结论】这些物理性状表明土地整理区内土壤压实程度非常严重，必须采取相应措施改良压实的土壤，迅速提高土地的生产力。

Abstract:

【OBJECTIVE】The author plan to understand the soil compaction of land consolidation in loess Plateau area and formulate corresponding improvement measures to promote the optimal allocation and effective use of land resources【METHOD】The land consolidation project in Hougong Town Wenxi County was conducted in this paper, to investigate the soil bulk desity, compaction, the water content and infiltration rate. 【RESULT】The result showed:(1) In comparison with the general farmland soil, the soil bulk desity increased by 1.34 times and compaction increased by 484 times in land consolidation. (2)The rate of initial infiltration was 1.21mm/10min and the rate of steadily infiltration was 0.7mm/10min in compaction soil,was equal approximately to 16% and 28% in general farmland soil. 【CONCLUSION】These physical properties indicated that land consolidation area is very serious level of soil compaction, we must take appropriate measures to improve compaction of the soil, rapidly improving land productivity.
