“双碳”视域下的“环境土壤学”教学改革

Teaching Reform of Environmental Pedology from the Perspective of“Double Carbon”

“双碳”目标自提出以来,就受到党和国家的高度重视,是加快我国生态文明建设和实现高质量发展的重要抓手。土壤是自然环境中碳捕集和封存的理想场所,然而目前环境专业的实践教学偏重土壤污染物的环境行为及其修复去除,对土壤固碳相关内容涉及较少。环境土壤学是涉及地学、化学、微生物学、环境工程的一门交叉学科,知识点零散,一些学生难以在知识点之间建立逻辑联系,并形成对课程的连贯理解。此外,“双碳”政策的出台意味着环境土壤学的前沿方向变化跨度大,对学生的自主学习和创新探索能力提出了更高的要求。基于以上问题,重塑教学内容,利用知识网络构建法和项目式学习法(project-based learning,PBL)改革教学过程,以期提高学生的自主探索和创新能力,培养顺应“双碳”时代的创新型人才。

The“double carbon”strategic goal,has been highly valued by the Party and the state since it was put forward.It serves as a crucial catalyst for expediting the construction of ecological civilization in China and achieving high-quality development.The soil provides an optimal environment for carbon capture and storage.However,the current teaching approach in environmental studies primarily focuses on the behavior and remediation of soil pollutants,with comparatively less emphasis on the crucial aspect of soil carbon sequestration.The field of Environmental Pedology falls within the interdisciplinary realm of geosciences,chemistry,microbiology,and environmental engineering.However,due to the scattered nature of its knowledge points,it is difficult for students to establish logical connections between them and form a cohesive understanding of the subject matter.The implementation of the“double carbon”policy also brings about a significant shift in the forefront direction of Environmental Pedology,thereby placing higher demands on students’capacity for independent learning and innovative exploration.Based on the aforementioned issues,this study proposes to enhance the teaching content and reform the teaching process through the utilization of knowledge network construction methodology and projectbased learning(PBL)approach.This aims to foster students’independent exploration and innovation capabilities,as well as cultivate innovative talents who can adapt to the challenges posed by the“double carbon”era.
