| 摘 要： | 耕地利用系统对全球变化和人类福祉具有巨大影响。论文运用系统科学的理论与方法,探究耕地利用系统的概念、构成、运行、功能和特点,并构建耕地利用系统研究框架,对于深化土地系统科学、解决耕地利用中存在的各种问题具有重要的理论和现实意义。主要结论有：① 耕地利用系统是农业生产经营者在一定数量和质量的耕地上投入适量生产要素种植农作物,进而获得农产品及相应效益的自然—人工复合系统,由耕地子系统、经济子系统及社会子系统构成,具有显性和隐性双重结构。② 耕地利用系统运行及演化是自然生态过程、经济发展过程、社会演化过程耦合行进的结果,并涌现出经济、社会、生态功能,具有复合性、开放性、韧性和多等级性等特征。 ③ 耕地利用系统研究应遵循要素—结构—功能—机制—调控的理论框架,从各要素组成、作用关系及变化特征揭示不同要素的演化特征;从显性与隐性结构2个方面探索耕地利用系统结构及其转型规律;从经济、社会和生态功能3个方面探索功能演化及其对于结构转型的响应特征;从系统对外界环境变化的适应与调整机制、系统要素的相互影响与竞争替代机制、系统运行的信息传导机制、不同等级耕地利用主体协同与组织运行机制、耕地利用功能的涌现机制剖析耕地利用系统运行机制;针对不同情景、不同目标、不同主体,运用情景模拟法、多目标优化法、综合调控平衡法探究耕地利用调控策略。 |

| Abstract: | Cultivated land use system has a great impact on global change and human well-being. This study used the theories and methods of system science to explore the concept, composition, operation, functions, and characteristics of cultivated land use system and constructed the research framework of cultivated land use system, in order to promote the deepening of land system research and solve various problems. The main conclusions are as follows: 1) Cultivated land use system is a compound natural-human system in which agricultural producers and operators invest an appropriate amount of production factors in a certain amount and quality of cultivated land to plant crops, and obtain agricultural products and corresponding benefits. Cultivated land use system consists of cultivated land subsystem, economic subsystem, and social subsystem. It has explicit and implicit structures. 2) The operation and evolution of cultivated land use system is the result of natural ecological processes, economic development processes, and social evolution processes. It also has compound, open, resilient, and multi-level characteristics. 3) The study of cultivated land use system should follow the theoretical framework of element-structure-function-mechanism-regulation. This study revealed the action mechanism of different elements from the composition and influence relationship of various elements; analyzed the structure and transformation of cultivated land use from two aspects of explicit and implicit structure; revealed the impact of functions on structure from three aspects of economic, social, and ecological functions; analyzed the operation mechanism of cultivated land use system from the adaptation and adjustment mechanism of the system to the changes of external environment, the interaction and competition substitution mechanism of system elements, the information transmission mechanism of system operation, the coordination and organization operation mechanism of cultivated land use subjects at different levels, and the emergence mechanism of cultivated land use functions; and used scenario simulation method, multi-objective optimization method, and comprehensive regulation balance method to explore regulation strategies of cultivated land use. |
