| 中文摘要: |
| :耕地是珍贵而有限的自然资源，同时关系到农产品质量安全及生态安全，开展土壤地球化学调查，以生态地球化学理论为指导，同时兼顾大气干湿沉降物和灌溉水地球化学调查，科学量化耕地质量，为调整农业种植结构、促进科学合理施肥及土壤污染治理和贵州“大扶贫、大数据、大生态”三大战略服务。通过调查，获得了贵州省平坝区土壤中21项土壤养分指标和7项环境地球化学指标的基本统计量及地球化学背景值等参数，以及灌溉水和大气干湿沉降中元素含量。土壤地球化学背景值为农业发展提供了科学基础，由此提出土地利用建议。 |
| 英文摘要: |
| The cultivated land is rare and limited natural resource, is also related to agricultural product quality safe and environmental safe. The soil geochemical survey is guided by eco-geochemistry theory, meanwhile taken atmospheric deposition and irrigation water geochemical survey in account, the cultivated land is quantified scientifically, it will service the agricultural plantation structure, scientific and reasonable fertilization , soil pollution treatment and the Three Main Strategies of ‘big poverty alleviation, big data and big ecology’ in Guizhou. Bu investigation, it achieved basic statistics of 21 soil nutrients, 7 environmental index and geochemical background value in the soil of Pingba, Guizhou, the element content of irrigation water and atmospheric deposition. The soil geochemical background value affords scientific basis for agricultural industry development, then the suggestions of land utilization are given. |
