摘要

With the rapid socio-economic development, the relationship between man and land is becoming increasingly tense, and under the premise of guaranteeing food security and ecological safety, it is urgent to consider ‘Production-Living-Ecological’ functions of cultivated land in spatial planning of the national territory and the coordinated development of the region. Therefore, by exploring the evolution of the ‘Production-Living-Ecological’ functions of cultivated land, the analysis of the coupling coordination, the direction of deviation and the driving factors, we can provide data support for the utilisation and diversified management of cultivated land. This paper takes Yunnan Province as the study area, integrates the time-series land use remote sensing data from 2005 to 2020 and the statistical yearbook data of various departments, states and cities, and selects 20 indexes, such as the level of grain yields and the density of agricultural employees, to construct an evaluation system of the ‘Production-Living-Ecological’ functions of cultivated land, and adopts the entropy weighting method, the comprehensive index evaluation method, the mechanical balance model and the geographic probe to explore the temporal and spatial differentiation pattern, coordination degree, deviation direction and driving factors of the ‘Production-Living-Ecological’ functions of cultivated land in Yunnan Province. Entropy weight method, comprehensive index evaluation method, mechanical balance model and geographic detector were used to investigate the spatial and temporal pattern of the ‘Production-Living-Ecological’ functions of cultivated land in Yunnan Province, the degree of coordination, the direction of deviation and the driving factors. The results show: 1) The production, living and ecological functions of cultivated land in Yunnan Province were all improved from 2005 to 2020, and the differences between the regions of each function increased. 2) Differences in the spatial distribution patterns of the ‘Production-Living-Ecological’ functions of synergistic and trade-off areas and cultivated land. 3) Most of the cities and towns in Yunnan Province are dominated by living and ecological functions, with production functions to be improved. 4) The driving force of the ‘Production-Living-Ecological’ functions of cultivated land in Yunnan Province is not the same among different driving factors. Through this research, we aim to provide more appropriate optimisation of cultivated land use, increase the coordination of the ‘Production-Living-Ecological’ functions of cultivated land in each state and city, and balance the development of the ‘Production-Living-Ecological’ functions of cultivated land in each state and city.
