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.
