苏北沿海地区土地质量地球化学评价及空间分布研究——以射阳兴桥镇为例

Geochemical assessment of soil quality and spatial distribution in the coastal land of northern Jiangsu——A case study of Xingqiao Town in Sheyang County

以江苏射阳兴桥镇1∶5万多目标区域地球化学调查成果数据为基础建立评价模型,对射阳兴桥镇耕作层土壤进行土地质量地球化学评价及空间分布研究,掌握兴桥镇土地质量现状,并对工作区农业发展规划和优质农产品种植提出合理建议。

This work is based on the multi-target geochemical investigation data at a scale of 1：50 000 in Xingqiao Town of Sheyang County, Jiangsu Province. An assessment model was established to conduct geochemical evaluation of land quality for the cultivated ho- rizon soil in Xingqiao Town and to determine the spatial distribution. This paper also presents the status of land quality, and proposes reasonable suggestions on agricultural development planning and high quality cultivation of agricultural products in the study area.
