| 中文摘要: |
| 通过对秦皇岛山区—平原—沿海一线土壤元素采样与化验分析，研究沿线土壤养分元素的空间分布特征。基于沿线105个采样点，分析了土壤养分的空间地球化学特征。结果表明：土壤养分综合等级在朱杖子乡以北为三等，双山子镇—大新寨插旗梁块段一等至三等均有分布，其他地段为四等。土壤养分综合指标林草地>农用地，养分综合指标山区生态用地>平原农业用地>沿海工业用地。本研究建立了秦皇岛山区至沿海的山区生态用地、山前农业用地、沿海工业用地3种不同土地利用类型的综合土壤地球化学剖面，可为秦皇岛地区农业绿色发展提供科学依据。 |
| 英文摘要: |
| Through the sampling and analysis of soil elements from mountainous to plain to coastal areas of Qinhuangdao， the spatial distribution characteristics of soil nutrient elements along the route were studied. Based on 105 sampling points along the route， the spatial geochemical characteristics of soil nutrients were analyzed. The results showed that the comprehensive grade of soil nutrients was the third grade in the north of Zhuzhangzi Town， the first to third grade in the section from Shuangshanzi Town to Daxinzhaichaqiliang area， and the fourth grade in other lots. The comprehensive soil nutrient index forest and grassland was larger than agricultural land， and the comprehensive nutrient index was sorted as mountain ecological land， plain agricultural land， coastal industrial land. This research work established a comprehensive soil geochemical profile of three different land use types， including mountainous ecological land， piedmont agricultural land and coastal industrial land， from the mountainous area to the coastal area of Qinhuangdao， which provided scientific basis for the green development of agriculture in Qinhuangdao. |
