Abstract

Abstract:

The rural area is a complex and giant system formed by the organic combination of core elements such as population, land and industry. In order to explore the interaction between rural population, land and industry, this paper used these three elements of rural development to construct the evaluation index system of the coupling coordination degree based on the county panel data of the Dongting Lake Eco-economic Zone. Then, the paper adopted the coupling coordination degree model to deeply portray the spatial-temporal differentiation of the coupling coordination of rural population-land-industry in Dongting Lake Eco-economic Zone. Results showed that the development of the subsystems with rural population, land and industry in the Dongting Lake Eco-economic Zone was generally very different and unbalanced; the development of rural population-land-industry in most counties was in the stage of coupling coordination, forming a spatial pattern centered on the developed area of Yueyang City in the east of Dongting Lake Eco-economic Zone and gradually spreading outward in the form of circles, which showed an overall upward trend year by year. The coupling coordination degree had four types: bare coordination, primary coordination, intermediate coordination and good coordination. The rural population-land-industry coupling coordination degree as a whole showed the characteristics of increasing from primary coordination to intermediate coordination in the study area.

Key words: rural area, population-land-industry, coupling coordination, spatial-temporal differentiation, Dongting Lake Eco-economic Zone
