作物种植面积遥感提取的实验设计与教学实践

Experiment Design and Teaching Practice of Crop Area Extraction Using Satellite Remote Sensing

为将农学基础实验课程建设的“两性一度”要求落到实处,设计了一个符合新农科培养目标的实验项目——基于时序遥感数据的江苏省典型作物种植面积提取及时空变化分析(RS-CAE),并以全省广泛种植的冬小麦为例,介绍了卫星遥感在作物种植面积提取中的实际应用。同时,从教学模式、课程思政、考核评价等方面对RS-CAE实验教学进行了改革探索。教学实践表明,学生通过RS-CAE实验的学习既拓展了卫星遥感与作物物候相关知识点的交叉融合,又掌握了文献调研、数据整理、方案实施、结果分析、成果展示等技能,有效提高了学生的科研素养与实践应用能力。

In order to realize the requirement of“two-essences and one-degree”in the construction of the basic agricultural science experiments,an experiment entitled the extraction and analysis of spatiotemporal variation of typical crop planting area in Jiangsu province is designed based on time-series satellite data,which meets the cultivation requirements of new agricultural science.And taking winter wheat,which is widely grown in Jiangsu province,as an example,we present practical applications of crop area extraction using satellite remote sensing.Meanwhile,the experimental teaching mode is reformed and explored from aspects of teaching mode,course ideology,and evaluation according to the student-centered educational idea and the blended teaching method.The teaching practice shows that students not only expand the cross-fertilization knowledge related to remote sensing and crop phenology,but also master the skills of literature research,data collation,program implementation,result analysis and reporting through the learning of this experiment,which effectively improves students’scientific research quality and practical application ability.
