| 中文摘要: |
| 空心村整治是农村土地综合整治的重要内容，在以土地可持续利用为核心的目标导向下，揭示空心村内典型土壤重金属污染情况是整治工作特别是构建耕层土体的先导环节。本文以黄淮海平原农区的禹城市为例，分析典型空心村在整治时可能涉及的村内道路、晾晒场院、坑塘底泥、林地表土、院落农地、院落实土、土墙墙体等7种土壤的As、Cd、Cr、Cu、Ni、Pb、Zn含量，利用单项污染指数和综合污染指数，按照有关国家标准，评价其重金属污染程度，为空心村改造中土壤的安全、合理利用提供依据。结果表明：前述7类参试土壤中，除院落农田的污染指数为0.85（污染等级为Ⅱ，属“较清洁”土壤）外，其余6类的综合污染指数均< 0.7（污染等级为Ⅰ，属“清洁”土壤），可直接用于空心村整治中的耕层土体重构。本研究基于整治利用导向进行了平原农区空心村典型土壤类型划分，揭示了其重金属污染状况，对于科学开展空心村整治、建设更加安全的高标准农田具有重要参考价值。 |

| Hollow village renovation is an important content of rural land comprehensive consolidation. Under the core goal of sustainable utilization of land, revealing heavy metal pollution in typical soils of hollow village is the guiding link of the consolidation work, especially the reconstruction of farmland. Taking Yucheng City of Huang-Huai-Hai Plain as an example, this paper aims to analyze the content of As, Cd, Cr, Cu, Ni, Pb and Zn in seven kinds of typical soils, namely the village roads, sunning grounds, pit-pond sediments, woodland topsoils, courtyard farmlands, courtyard soils and clay wall soils which may be involved in the reconstruction of typical hollow village. Individual pollution index and comprehensive pollution index were used to evaluate the degree of heavy metal pollution according to the relevant national standards in order to provide the basis for safe and rational soil utilization during the hollow village consolidation. The results showed that in the above 7 types of tested soils, except for the pollution index of courtyard farmland was 0.85(pollution level Ⅱ, belong to "less clean" soil), other six types were <0.7(pollution level Ⅰ, belong to "clean" soil), which could be directly used in the hollow village consolidation for reconstruction of topsoil for agriculture. This study revealed the heavy metal pollution condition in the typical soils of plain agricultural areas. It has important reference value to the consolidation of hollow villages scientifically and the reconstruction of safe and high standard farmland. |
