摘要
土地利用系统是一个具有开放性、随机性、代谢性、非孤立性和自组织等基本特征的复杂巨系统。它不仅在空间和功能上表现出不同的组合关系和结构格局,而且在时间上也表现出演替、此消彼长等规律。城市土地利用的变化也是城市发展过程中空间布局和结构变化的综合反映,它直接或间接地与城市人口、环境的改变及社会经济发展密切相关。依据2000年、2011年和2017年洪山区的土地利用类型在数量、空间格局上的变化,得出洪山区17年间土地利用变化的时空演变规律;选用边界维数指标刻画洪山区土地景观的分形特征,并对影响洪山区土地利用结构和形态变化的驱动力因素进行剖析。
Land use system is a complex giant system with the basic characteristics of openness,randomness,metabolism,non-isolation and self-organization.It not only shows different combinatorial relations and structural patterns in space and function,but also shows the law of succession,growth and decline in time.The change of urban land use is also a comprehensive reflection of the change of spatial layout and structure in the process of urban development,which is closely related to the change of urban population,environment and social and economic development directly or indirectly.According to the changes in quantity and spatial pattern of land use types in Hongshan District in 2000,2011 and 2017,the temporal and spatial evolution law of land use change in Hongshan District in the past 17 years was obtained,and the boundary dimension index was selected to describe the fractal characteristics of Hongshan District land use landscape.The driving factors affecting the change of land use structure and shape in Hongshan District were analyzed.
