- Abstract:
-
The investigation on transition of recessive land use and its eco-environmental impact strongly benefits the green economy. With the methods of synthetic index model, coupling coordination degree model and Geodetector, we discussed the spatiotemporal pattern, transition mode of recessive land use morphology and its coupling relationship with land eco-security in Fujian Province. The results indicate as follows. The recessive land use morphology index generally is on the rise, and it is gradually developing to a higher level. The recessive land use morphology index of coastal cities decreases from southeastern coastal to northwestern inland area in space. During the research period, land use transition shows characteristics of stages with the transition period showing the S-shaped evolution trend. The overall level of land eco-security in Fujian Province fluctuates and rises, and is closely related to the regional transition stage of recessive land use morphology. The land ecological level in the northwest inland area is higher than that in the southeast coastal area. In the past 15 years, the average coordination degree of coupling between recessive land use morphology and land-eco security in Fujian has increased from 0.44 to 0.61. The coordination of coastal cities is higher than that of inland cities. The major driving forces on the coordination include land use intensity, land output efficiency and endowment of ecological resources. In order to promote coordinated green development among cities, the government should apply recessive land use morphology and its rule of coordinated development with eco-security to land use and implement management policies according to local conditions.
