摘　　要：在滨海盐碱化地区,随着农村社会经济发展水平提高和城镇化速度加快,村庄废弃宅基地越来越多,急需整理复垦为耕地。论文通过田间试验研究,分析了村庄宅基地复垦前后土壤理化性质的变化情况,结果表明,复垦能明显降低耕作层土壤容重和增加宅基地土壤的入渗能力,特别是0~20cm土层的土壤容重明显减小,土壤饱和导水率比复垦前增大了约10倍;复垦模式I和复垦模式II均能显著提高土壤有机质含量和土壤微生物含量,降低土壤含盐量,提高土壤肥力;复垦模式II中,种植玉米的复垦土壤盐分降低最为明显,土壤微生物含量增大程度排序为番茄〉玉米〉茄子,种植番茄和玉米的复垦土壤中有机质含量提高较多。该研究可为滨海地区的宅基地复垦提供一定的理论依据。In coastal area ,with the improvement of rural social economic development level and urbanization speeding up ,more and more rural homestead urgent need reclamation .Based on field experiment research ,the change of soil physical and chemical proper‐ties of rural homestead reclamation was analyzed .The results showed that the reclamation could significantly reduce the Soil bulk density and increase the infiltration capacity of rural homestead ,especially in 0~20 cm soil layer soil bulk density was significantly decreased .The soil saturated hydraulic conductivity increased more than 10 times than before reclamation .The soil organic matter content and soil microbial content were significantly increased under the reclamation mode I and reclamation mode II .The soil salt content was also reduced and soil fertility was improved .For reclamation mode II ,the soil salt had an obvious reduction in corn field .The increased sort of soil microorganism content was tomato field 〉 corn field 〉 eggplants field .The tomato and corn of rec‐lamation were obtained more soil organic matter content than in eggplants field .The research could be used to provide certain theo‐retical basis for homestead reclamation in coastal area .
