中文摘要:
      为摸清耕地质量“家底”,服务现代山地特色高效农业发展,贵州在全国率先完成全省1∶5万耕地质量地球化学调查评价工程。其方法技术总体遵循现行技术标准的基本原则和要求外,结合贵州山地耕地实际,对耕地表层土壤样点布设、耕地土壤养分等级评价、耕地土壤环境质量评价,以及耕地土壤质量综合等级评价等,进行了探索与创新,从而进一步完善了调查评价有关方法技术,对贵州特殊地质背景和自然地理环境条件下的耕地质量地球化学调查评价工程的圆满完成,起到了较好的作用。本文将重点介绍上述内容,并对有关问题进行讨论,以丰富和完善这一领域的方法技术。
英文摘要:
      In order to find out the cultivated land quality and serve the development of modern efficient agriculture with mountainous features, Guizhou took the lead in completing the province’s 1∶50000 land quality geochemical survey and evaluation project. The method and technology generally follow the basic principles and requirements of the current technical standards, combined with the actual conditions of the cultivated land in Guizhou, the layout of surface soil samples, the evaluation of the soil nutrient grade of the cultivated land, the environmental quality of the cultivated land, and the comprehensive grade evaluation of the soil quality of the cultivated land. Exploration and innovation have been carried out to further improve the survey and evaluation methods and technologies, and have played a good role in the successful completion of the geochemical survey and evaluation project of cultivated land quality under the special geological background and natural geographical environment in Guizhou. In this paper, it will focus on the above content and discuss related issues in order to enrich and improve the methods and technologies in this field.
