摘要:

土地利用功能转型可实现土地利用功能协调,是实施区域可持续发展的重要路径。从功能协调角度构建土地利用功能转型分析框架,利用江苏省1995年、2000年、2005年、2010年和2015年5期遥感影像及相关资源利用和社会经济数据,构建三级土地利用功能评价体系,以县域为评价单元,通过三角模型和空间相关分析等方法,定量解析江苏省土地利用功能时空演变特征及其与土地可持续利用目标的协调状况。研究结果显示:(1)研究期内,江苏省土地利用功能总水平提升减慢,其中生产、生活功能不同程度提升,生态功能明显下降。(2)生产、生活功能空间集聚不突出,生态功能的热点、冷点区域呈“Y”型集聚分布。(3)不同功能区功能协调性态势不一,重点开发区和限制开发区可持续发展态势总体良好,优化开发区可持续发展程度较弱并持续恶化。建议江苏省在落实发展蓝图和空间规划的过程中,应优先推进苏南现代化示范区建设,重点实施重点开发区生活功能转型、Ⅰ类限制开发区生产功能转型策略,并严格落实禁止开发区的生态保护责任等差别化管理策略。

Abstract:

The land use function transition is an important measure to promote the coordination of land use functions and achieve sustainable regional development. This paper constructs an analysis framework for land use function transition based on sustainable development from the perspective of functional coordination, and uses the five phases of remote sensing images of Jiangsu province in 1995, 2000, 2005, 2010 and 2015, as well as related resource utilization and socio-economic data to construct the three level evaluation system of land use function. Taking the county as an evaluation unit, through triangle model and spatial correlation analysis, the spatial-temporal evolution characteristics of land use functions are quantitatively analyzed, and the coordination status of land use functions is proposed for sustainable land use in Jiangsu province. This paper has obtained the following main findings: (1) During the research period, the overall level of land use function in Jiangsu province has increased at a slower pace. The production and living functions have enhanced in different degrees, and the ecological function has significantly been reduced. (2) The spatial aggregation of production and living functions of land use in this province has not been obvious, and the areas of ecological functional hot spots and cold spots have a "Y"-shaped pattern of agglomeration distribution. (3) The sustainable development of different functional areas has not been the same. The sustainable development of key development zones and restricted development zones has been generally good. The sustainable development of optimizing development zones has been weak and continued to deteriorate. In the process of implementing development plans and space planning, we suggest that priority should be given to construct the modern demonstrative region in Southern Jiangsu, the key development zones should be focused on the living function transition, the restricted development zones (I type) should be focused on the production function transition, and the forbidden development zones should be implemented strictly to protect the environment.
