Abstract:

Qingyang City is located in the loess plateau region of eastern Gansu Province, which is endowed with abundant natural resources and serves as one of the key zones for supplying energy to the country. It plays a crucial role in fostering development, safeguarding ecological integrity, promoting high-quality growth, and enhancing environmental protection within the western region. Exploring and analysing the ecological risk patterns and coupled the coordination of the production-living-ecological space landscapes is of profound significance. This study focused on Qingyang, located in the loess plateau region of eastern Gansu Province, employing methodologies such as land use transfer matrix analysis, landscape ecological risk assessment models, and coupling coordination degree models to investigate and analyze changes in land use structure from 2000 to 2020. This work also incorporated the patterns of landscape ecological risk, and the degree of coupling coordination among production-living-ecological space based on comprehensive evaluation. The following results were obtained: (1) Over the last two decades, the ecological and residential space in Qingyang City has consistently increased year after year, whereas the area designated for production has exhibited a gradual decline. (2) The overall landscape ecological condition of Qingyang City is in a low-risk state, and the distribution of the degree of risk is “low in the east and high in the west.” (3) The degree of coupling coordination of the production-living-ecological space is well developed and concentrated, presenting a distribution of “high in the south and low in the north.” The coupling coordination area is expanding continuously year by year, while the uncoordinated area is shrinking. (4) By analyzing the coupling coordination of the production-living-ecological space using natural and social economic factors, it is concluded that socioeconomic factors have a more significant impact on this. Therefore, the driving factors are integrated with the needs and characteristics of the production-living-ecological space, and the layout of the production-living-ecological space is optimized to facilitate the coordinated development of the ecological risk pattern of the landscape, enhance the regional ecological security of the landscape, and advance the sustainable development of the ecological economy of Qingyang City.
