| 摘 要： | 东北黑土地是世界四大黑土区之一，以高有机质和高肥力而著称，在保障国家粮食安全中具有举足轻重的地位.东北平原大地构造位置上属于欧亚板块大陆边缘活动带，经历了多期复杂地质作用和环境演化过程，逐渐形成如今的黑土地.黑土矿物组分主要包括伊利石、蛭石、高岭石和蒙脱石.黑土地被开垦后农田化过程中存在黑土退化、地质调查方法不统一、基础地质研究薄弱、综合研究不足等主要地质问题.目前主要通过土地质量地球化学调查、遥感等技术手段，已在黑土地质量状况、土地质量限制因子及其交互作用机理、黑土形成时代及其环境、黑土地关键带天-空-地一体化调查方法、富硒土地资源筛选等领域取得重要研究进展.今后地质工作者应在长观基地监测与国际联合公关、黑土地修复地质方案研究与实践、元素地球化学循环机制研究、黑土形成演化理论、土地资源“双评价”技术方法等方面加强探索及综合研究，确保黑土可持续利用.

| Abstract: | The black land in Northeast China, as one of the significant four black soil areas in the world, known for high organic matter and high fertility, plays a pivotal role in ensuring national food security. The Northeast Plain is tectonically located in the active zone of Eurasia Plate continental margin, undergoing multistage complex geological process and environmental evolution and gradually forming the present black land. The mineral compositions of black soil mainly include illite, vermiculite, kaolinite and montmorillonite. With black soil degradation in the land transferring process into farmland after reclamation, there are also some major geological problems such as disunified geological survey methods, weak basic geological study and inadequate comprehensive research. At present, by means of land quality geochemical survey and RS technology, significant progress has achieved in the fields of black land quality, land quality limiting factors and interaction mechanism, black soil formation time and environment, integrated satellite-aero-ground survey methods for key area of black land and screening of selenium-rich land resources. The future exploration and research should focus on long-term observation base monitoring with international cooperation, geological program for black land restoration, elemental geochemical cycle mechanism, black soil formation and evolution theory, and land resources "double evaluation" techniques to ensure the sustainable utilization of black soil. |
