结合峡江水利枢纽工程建设中的库区抬田研究课题开展库区多元结构抬田土壤肥力及水分变化规律研究。通过四年的水稻种植试验结果分析表明：抬田示范区水稻耕作层的有机质、全氮、碱解氮、有效磷、速效钾含量指标大部分比未抬田对照区低，水稻土壤耕作层受到抬田影响，土壤养分含量在一定程度上有所降低，水稻生长所需土壤养分含量在一定程度上受到破坏。采取秸秆还田配合化肥施用后，土壤有机质含量得到了有效的改善，同时，也起到调节土壤中全氮和碱解氮的含量，培肥土壤的作用。其次，抬田区耕作层土壤的干容重较抬田前有所降低，田间持水率得到一定程度的提高，土壤结构性能得到了一定程度改善。

This paper, analysised the variation rules of soil fertility and moisture to the multi-base Structure by the project of Xia jiang reservoir construction. Through four years's experimental research showed that most of the indicators including total nitrogen, nitrogen, phosphorus, potassium content of the Lifted demonstration area were lower than the not lifted field area, which indicated that the topsoil was affected by lifting field , the soil nutrient content was decreased in some extent, and soil nutrient content needed for growth was undermined. After taking straw with chemical fertilizers, soil organic matter had been effectively improved, and it also modulated the total nitrogen content of the soil and nitrogen,improved soil fertility role.What more,dry bulk density of the topsoil in the lifted field area was lower than before lifted ,the field capacity had increased in some extent, and soil structural properties had been improved.
