黄土高原区复垦村庄土壤肥力评价——以山西省泽州县西郜村为例

Evaluation of Soil Fertility of Reclaimed Village in the Loess Plateau Area——A Case Study of Xigao Village,Zezhou County,Shanxi Province

以黄土高原区复垦村庄山西省泽州县西郜村为研究区,采集和测定了村庄中不同用地类型的土壤,从土壤的物理、大量养分元素和微量元素3方面构建了复垦村庄肥力综合评价体系,并通过将粗糙集理论与综合指数法相结合的方法对复垦前后村庄土壤肥力状况进行了对比分析。结果表明:村庄复垦活动有效提升了区域的土壤肥力,但复垦耕地的土壤肥力与标准耕地之间相比仍然存在一定差距,不同地类的土壤肥力改良程度有所不同,其中旧宅的改良效果最好,菜地的改良效果相对不显著。研究结果可为村庄进一步开展土壤肥力提升改良活动提供一定借鉴。

We selected Xigao Village of Zezhou County, Shanxi Province in the Loess Plateau as the research area, collected and measured soil samples according to different types of land in the village and established the soil fertility evaluation index system from perspectives of physical attributes, nutritional attributes and trace elements, and conducted the contrast analysis of soil fertility before and after the reclamation work. The results are as follows. The reclamation activities effectively elevated the soil fertility in the village, but the gap between soil fertility in the reclaimed soil and standard arable land still existed. In addition, the degree of the enhanced soil fertility varied among different types of land, the degree in old residential land was elevated the most, while the degree in vegetable field was not remarkable. The research results could provide some reference for conducting activities to enhance soil fertility in the reclaimed village.
