中文摘要: 经过各地多部门采取有效措施、积极推进,东北黑土地保护利用取得了显著成效。目前,东北黑土地保护利用已经上升到国家战略,被纳入相关国家规划或纲要中,科学研究取得了重大进展。通过实施东北黑土地保护利用试点项目,黑龙江省、吉林省、辽宁省和内蒙古自治区已经将黑土地保护利用纳入重要工作日程,因地制宜、分区域制定了黑土地保护利用措施,建立了“梨树模式”和“龙江模式” ;黑土地6个土壤类型耕地地力得到提高,黑土地保护利用工作达到预定目标,社会和民众参与意识明显提升。此外,各级政府通过不断完善相关条例规范,实现黑土地保护利用有章可循,下一步逐步完善国家层面相关法规制度,让黑土地保护利用有法可依。然而,东北黑土地保护利用仍然面临着现有耕作方式能否保持住黑土层厚度、浅薄层黑土能否通过技术创新恢复至中厚层黑土、如何通过低成本投入实现白浆土障碍消减与培肥、黑土区可容忍的风蚀和水蚀量是多少等一系列问题。在未来的工作中,应该加强顶层设计,充分发挥《东北黑土地保护规划纲要(2017—2030年)》和《国家黑土地保护工程实施方案(2021—2025年)》对东北黑土地保护利用的指导作用,在北纬45°以北的黑土带上建立大于4×104 km2黑土地保护区,实现中厚层黑土的永续利用;集中力量破解浅薄层黑土耕地地力提升与粮食产能高效的肥沃耕层构建技术瓶颈;建立以长坡为研究对象的水土流失长期观测场,重点攻关坡耕地区域内系统降能排水技术和沟蚀控制技术;设立土壤风蚀监测站点,形成监测网络,进行实时观测,为制定防风蚀技术对策提供重要参考。
Abstract:The conservation and utilization of black soil have achieved remarkable results under effective measures and active promotion taken by different departments in China. At present, the conservation and utilization of black soil have been upgraded to national strategy and incorporated into related planning and outline, major scientific advances have been achieved. The black soil conservation and utilization have also been listed into the important governmental schedules in Heilongjiang Province, Jilin Province, Liaoning Province, and Inner Mongolia Autonomous Region in Northeast China. The promotional mechanisms of black soil conservation and utilization have been established, approaches of black soil conservation and utilization have been proposed according to the local conditions, Lishu model and Longjiang model were established, soil fertility of six soil types in black soil has been enhanced, mass satisfaction has reached 100% according to the questionnaire survey, social and public participation awareness has been significantly improved. Additionally, black soil conservation and utilization could rely on related regulations and specifications under continuous improvement, and will rely on related national law in the future. Nevertheless, there are still a range of problems to be solved for further work in black soil conservation and utilization, such as whether the thick black soil layer can be maintained under current practices, whether soil with thin black soil layer can restore to soil with thick black soil layer by the technology innovation, how to simultaneously realize obstacle abatement and soil fertilization of albic soil with low input, and what are the threshold values of wind erosion and run off in black soil zone. In the future, black soil conservation and utilization should focused on strengthening top-level design, playing a full guiding role of Outline of the Northeast Black Soil Conservation (2017-2030) and Implementation Programme of National Black Soil Conservation Project (2021-2025), establishing black soil conservation zone in the north of black soil zone (N 45°) with area of more than 4×104 km2 in order to reach the objective of black soil sustainable utilization, breaking through technical bottlenecks of constructing fertile cultivated layer for soil with thin black soil layer in order to realize improvement in black soil fertility and enhance the crop yield, building field observation stations with long slope in sloping arable areas focused on drainage technology with low energy and controlling groove erosion, setting up soil wind erosion monitor network in order to provide important reference for developing technology of controlling wind erosion.
