为了摸清土地利用形态转型的规律,促进绿色经济的发展,以福建省9个设区市为研究对象,采用综合指数模型、耦合协调度模型和地理探测器方法,探讨了福建省土地利用隐性形态时空特征、转型模式并分析其与土地生态安全的耦合协调性特征。结果 表明:福建省土地利用隐性形态指数总体呈上升趋势,形态上逐渐往高级发展,沿海城市土地利用隐性形态指数比内陆城市高。研究期内土地利用转型存在阶段性特征,在一定周期内呈现出“S型”的演化态势。土地生态安全水平总体呈波动上升态势,并与地区所处的土地隐性转型模式密切相关,西北内陆地区土地生态水平总体比东南沿海地区高。近15年来福建土地利用隐性形态与土地生态安全耦合协调度均值由0.44上升至0.61,沿海城市协调性高于内陆城市; 协调性差异的主要影响因素是土地利用强度、土地产出效益和生态资源禀赋。应当将土地利用隐性形态转型及其与生态安全的协调发展规律应用到土地利用中,因地制宜地施行管理政策,促进城市间协同绿色发展。
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.
