国家自然科学基金“土地科学和自然资源管理”申请代码领域研究格局、热点透视与发展展望

支持基础研究是国家自然科学基金的职责使命。自然资源管理是地理科学交叉融合创新的重要领域。划分国家自然科学基金土地科学和自然资源管理申请代码领域的研究方向，分析该领域申报与资助格局，透视研究热点，提出发展展望。研究发现：2021年以来土地科学和自然资源管理领域的申报格局以交叉且偏向人文要素研究为主，交叉类研究占55%以上，人文要素为主类研究占30%，自然要素为主类研究占15%；以土地资源为对象研究占73%，以生态资源为对象占14%，以其他自然资源为对象的研究占13%。资助格局中土地资源类项目占主导，在75%以上，其他自然资源资助比例不高且资助率不稳定，在土地资源中，农用地、建设用地与土地系统是主要资助领域。为推动自然资源管理领域的健康持续发展，要创新该领域研究范式，增强基础研究属性，树立交叉融合研究典范，坚持申请代码初衷内涵。

Research patterns,hotspots and development prospects of land resource and natural resource management field within the National Natural Science Foundation of China

Supporting fundamental research is the responsibility and mission of the National Natural Science Foundation of China (NSFC). Natural resource management is an important research field of interdisciplinary integration and innovation in geographical sciences. This paper constructs a classification framework for research interests from the perceptive of logic and applicability, classifies relevant research interests in land sciences and natural resource management of geographical science of NSFC, analyzes the existing pattern of projects application and funding in this field, inspects the research hotspots, and proposes the development prospects of this field. Results show that: The application pattern in natural resource management since 2021 is dominated by the intersectional and human element-oriented studies, with over 55% of the intersectional category, 30% of the human element-oriented category, and around 15% of the natural element-oriented category, and from the perspective studied objects, around 73% is the land resource-oriented studies, around 14% of the ecological resource-oriented studies, and around 13% of the other natural resource-oriented studies; the funding pattern of projects is dominated by land resource studies, at more than 75%, while other natural resource funding is low in number and unstable in rate; agricultural land, construction land, and land use system are the main funding fields of land resources. To promote the healthy and sustainable development of the natural resource management research, it is necessary to innovate the research paradigm in this field, set an example of interdisciplinary integration research for geographical science, enhance its attributes of fundamental research, persist in the initial connotation of the code set, and prevent the polarization of the research pattern.
