西北旱区农业遥感的需求分析与发展建议

Demand analysis and development suggestions for agricultural remote-sensing in arid regions of Northwest China

【目的】文章旨在分析我国西北旱区农业发展趋势的基础上,探讨西北旱区农业遥感发展存在的机遇与挑战,并为发展西北旱区农业遥感提出相应建议。【方法】该文分析了特色农业资源调查、抗旱种质资源选育、现代农业发展、区域耕地保护、乡村振兴、推动落实“一带一路”倡议等西北旱区农业发展对农业遥感技术的迫切需求,在此基础上探讨了作物对象众多、自然条件苛刻、新平台新数据大量涌现、现有遥感产品难以直接应用、实地观测数据和区域专家知识缺乏等西北旱区农业遥感发展所面临的问题;指出了旱区发展农业遥感技术在国家政策、科技发展等方面的机遇,并提出了相应的发展建议。【结果】西北旱区农业发展对农业遥感技术的需求极为迫切,但当前的农业遥感算法和农业遥感产品难以满足西北旱区农业发展的定制化需求。【结论】通过构建旱区特色农业遥感样本数据库、加强旱区特色农业遥感算法研究、建立西北旱区盐碱地“天—空—地”立体监测网络、完善全国农业遥感区域网络、建立旱区农业遥感多级合作机制与平台等方式,加强旱区农业遥感技术和平台建设。总之,助力农业新质生产力的发展是当前西北旱区农业高质量发展的迫切任务,也是促进农业遥感学科发展的必然趋势。

[Purpose]This paper aimes to analyze the agricultural development trends,explore the opportunities and challenges in the development of agricultural remote-sensing,and put forward corresponding suggestions for the development of agricultural remote-sensing in the arid regions of Northwest China.[Method]The paper analyzed the urgent needs for agricultural remote-sensing technology in aspects such as investigation of characteristic agricultural resources in arid areas,selection of drought-resistant germplasm resources,development of modern agriculture in arid areas,regional farmland protection,rural revitalization in arid areas,and implementation of the"Belt and Road"initiative.On this basis,this paper discussed the problems faced by the development of agricultural remote-sensing in the arid areas of Northwest China,such as multiple crop objects,harsh natural conditions,appearance of new platforms and new data,difficulties in direct application of existing remote-sensing products,and lack of field observation data and regional expert knowledge.However,national policies and scientific development provided opportunities for the development of remote-sensing technology in arid areas.And corresponding development suggestions were put forward.[Results]Agricultural development in the arid areas had an extremely urgent need for agricultural remote-sensing technology,but the current agricultural remote-sensing algorithms and products were difficult to meet the customized needs of regional agricultural development in the arid areas of Northwest China.[Conclusion]Through constructing sample databases for agricultural remote-sensing with characteristics of arid areas,strengthening the research on algorithms for agricultural remote-sensing with characteristics of arid areas,establishing a three-dimensional sky-ground monitoring network for saline-alkali lands in northwest arid areas,improving the national agricultural remote-sensing network,and establishing a multi-level cooperation mechanism and platform for agricultural remote-sensing in arid areas,the development and application of agricultural remote-sensing technology will be strengthened in arid regions of Northwest China.In general,the promotion of the development of new agricultural productivity is an urgent task for the high-quality development of agriculture in the arid areas of Northwest China,which is also an inevitable trend for the discipline of agricultural remote sensing.
