Spatial Differentiation and Tradeoff–Synergy of Rural Multifunction at the County Scale in Anhui Province in the China’s Traditional Agricultural Areas

Abstract

The study of rural multifunction interaction has ignored the spatial differentiation characteristics, so it is necessary to reveal in-depth the spatial interaction relationship of rural multifunction interaction on the basis of type division and pattern recognition at the county scale. Taking Anhui as a case study, based on the county scale, the paper constructed an index system of rural multifunction evaluation, and comprehensively applied the improved entropy method, spatial autocorrelation model, and Spearman correlation coefficient to study the temporal-spatial characteristics and tradeoff–synergy relationship of rural multifunction from 2000 to 2020. The results showed that (1) the overall rural production function at the county level in Anhui showed an upward trend, showing a spatial pattern of “low in the south and high in the north”. The rural life function was gradually weakened, showing the characteristics of gradual decline from suburban to exurb. The rural ecological function increased, showing a high value distribution in areas with rich mountains and hills or a dense water network. (2) The spatial concentration of HH (High-High) and LL (Low-Low) positive correlation types of rural production, life, and ecological function was significant during the study period. The negative correlation types of HL (High-Low) and LH (Low-High) had low spatial agglomeration and showed discrete distribution. (3) There was a spatial synergistic relationship between rural production and life function at the county scale in Anhui Province. The tradeoff–synergy relationship between rural production and ecological function and between rural life and ecological function showed a trend of synergistic–tradeoff fluctuation. The spatial difference of the rural multifunction tradeoff–synergy relationship was significant during the study period. (4) In the future, we should change the situation that the expansion of rural production function compresses rural life and ecological function, and promote rural life and ecological function to promote the benign and coordinated development of rural multifunction at the county scale in traditional agricultural areas.

The Relationship between the Spatial and Temporal Evolution of Land Use Function and the Level of Economic and Social Development in the Yangtze River Delta

“…Spatial heterogeneity existed among the four functions in the Yangtze River Delta region, and the overlapping and competing coexistence of functions would result in concurrent synergy/balance relationships [65], which would increase multifunctionality and reduce trade-offs for sustainable regional development. This study diagnosed the synergistic/balancing relationships between functions and their degree of action based on the Spatial heterogeneity existed among the four functions in the Yangtze River Delta region, and the overlapping and competing coexistence of functions would result in concurrent synergy/balance relationships [65], which would increase multifunctionality and reduce trade-offs for sustainable regional development. This study diagnosed the synergistic/balancing relationships between functions and their degree of action based on the correlation coefficients' positive and negative absolute magnitude.…”

Exploring the motivations for rural tourism in China during the COVID-19: The existence of a single motivation

“…Since 2022, rural tourism has recovered 92% compared to the same period in 2019, making it one of the tourism categories with the strongest recovery momentum. Anhui Province, located in central China, is a traditional agricultural province with rich agricultural and rural resources [6]. The region is close to the economically developed and densely populated Yangtze River Delta region, with a large consumption capacity for rural tourism, and during the epidemic, rural tourism in Anhui Province showed explosive growth.…”

Research on multilevel evaluations and zones of territorial spatial functions in Yibin, China

“…There are differences in the components or quantity compositions of spatial elements in each region, the effect of natural evolution, and human activities, which result in various spatial patterns (Xie et al, 2021a;Zhao et al, 2022b). The failure of those patterns to adapt to sustainable human development is regarded as spatial dysfunction, which can be balanced by artificial planning constraints Zhang, 2022). The evolution of territorial space also follows the general laws of geography: the initial pattern and process determine the pattern and the corresponding functions, while the pattern in turn affects the evolution of the process (Fu, 2002;Brooks and Lee, 2019).…”
