“新三农”视域下中国耕地利用的可持续集约化：概念认知与研究框架

耕地利用的可持续集约化为保障粮食安全、农业绿色发展和资源永续利用提供了新思路,对于深化农民主体地位、夯实农业发展的现代化导向、破解“新三农”复杂的问题集合具有重要的现实意义。系统梳理国外可持续集约化的思想缘起,辨析可持续集约化的内涵差异,厘清“新三农”视域下中国耕地利用可持续集约化的逻辑本源;基于要素融合—结构重整—功能优化的运行轨迹,遵循耕地利用系统过程—格局—机制—效应的逻辑进路,尝试从学理辨析、水平测度、演化机理和优化调控等方面厘清耕地利用系统基本问题域并阐释其研究主题,构建耕地利用可持续集约化的研究框架。探索性提出未来研究需重点关注的农业生态空间—人地关系—耕地利用可持续集约化等科学问题,探讨因素+机理、功能+系统、过程+格局、尺度+界面的关键路径。

Conceptual cognition and research framework on sustainable intensification of cultivated land use in China from the perspective of the "New Agriculture,Countryside and Peasants"

Promoting sustainable intensification of cultivated land use (SICL) has provided a new idea for ensuring food security and green development of agriculture and sustainable use of resources. It is of important practical significance to deepen the dominant position of farmers, strengthen the modernization orientation of agricultural development, and solve the problem "New Agriculture, Countryside and Peasants", which is a complex collection of problems. This paper reviews the research on the ideologial origin of sustainable intensification abroad, identifies the connotation differences of SICL, and clarifies the logic origin of SICL of China under the background of "New agriculture, Countryside and Peasants". Based on the trajectory of "factor fusion-structural reorganization-functional excellence", following the logical approach of "process-pattern-mechanism-effect" in the system of cultivated land use, this paper clarifies the problem domain of cultivated land use system from the aspects of theoretical analysis, level measurement, evolution mechanism and optimal regulation, so as to construct a research framework of SICL. Finally, it proposes the scientific issues of "agricultural ecological space-human-land relationship-SICL", and discusses the significance and key issues of "factor & mechanism, function & system, process & pattern, scale & interface".
