摘要
耕地是人类生存及社会经济发展的重要保障性资源,具有重要的物资生产能力。通过对长江中游城市群耕地多功能转型及其协同发展对缓解快速城镇化过程中复杂的社会矛盾,促进城市经济可持续发展的影响的考察,利用社会经济及landsat监测等数据,探究土地利用转型于多功能水平的关系。研究表明,长江中游城市群的耕地、林地、草地与建设用地之间的转换最为显著。武汉都市圈、环长株潭城市群土地利用转型显著,环鄱阳湖城市群土地利用多样性较好。耕地利用的生产经济功能—社会保障功能整体上在波动中保持权衡,生产经济功能—生态景观功能整体上保持权衡发展状态,社会保障功能—生态景观功能整体上在波动中保持协同发展。
Arable land is an important basic resource for human existence and social and economic development,which possesses significant production capacity of goods and materials.This paper examines the impact of the multi-functional transformation and the coordinated development of cultivated land in the urban agglomeration at the middle reaches of the Yangtze River on the alleviation of the complex social contradictions in the process of rapid urbanization and on the promotion of the sustainable development of urban economy.By making use of the social economy and the Landsat monitoring data,it explores the relationship between land use transformation and multi-function level.The findings show that the transformation between cultivated land,forest land,grassland and construction land in the urban agglomeration at the middle reaches of the Yangtze River is the most significant.The land use transformation is significant in Wuhan Metropolitan Area and in the urban agglomeration around Changsha-Zhuzhou-Xiangtan,and in the urban agglomeration around Poyang Lake the land use diversity is better.The productive and economic function--the social security function of farmland utility as a whole keeps its balance during the fluctuation,the productive and economic function--the ecological landscape function as a whole keeps a state of balanced development,and the social security function--the ecological landscape function as a whole keeps a coordinated development in the fluctuation.
