平原农区空心村典型土壤的重金属污染评价 ——以山东省禹城市为例
Consolidation and Using Oriented Evaluation of Heavy Metal Pollution in Typical Soils of Hollowed Villages of Plain Agricultural Zones:A Case Study of Yucheng City, Shandong Province, China
摘要
Abstract
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 levelⅡ, 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.关键词
