城市边缘区生态承载力时空分异研究——以大连市甘井子区为例Urban fringe area Ecological carrying capacity space-time evolution research:the case of Ganjingzi District,Dalian
Abstract
The urban fringe area is the expansion area of the urban center urban area's economic industry,urban population,and urban traffic.Urbanization in the fringe urban area means the transformation of the economic and industrial structure of the fringe urban area due to the rapid urbanization,and the expansion of urban population and urban land use.The phenomenon of structural changes is mainly reflected in changes in urban land use structure, urban green space structure,population agglomeration,and evolution of urban ecological carrying capacity.With the continuous development of the urbanization of urban fringe areas, how to improve the infrastructure of urban fringe areas based on urbanization,the planning of urban construction land in urban fringe areas,and the level of eco-construction in urban fringe areas are also receiving widespread attention.In order to better promote the harmonious and sustainable development of urbanization,change the economic development mode of the urban fringe and promote the construction of urban ecological civilization,the research on the ecological carrying capacity of the urban fringe area can not be ignored.
Urban ecological carrying capacity is based on modern physical geography and urban ecological planning theory.Based on the characteristics of urban ecological carrying capacity at home and abroad,this paper discusses the temporal and spatial evolution characteristics of ecological carrying capacity in urban fringe.The ecological carrying capacity of the urban fringe zone proposed in this paper means that under the background of rapid urbanization development in urban fringe areas,the urban land use space continues to expand,the infrastructure in urban fringe areas is improved,and the ecological carrying capacity of urban fringe areas is gradually affected.process.At the same time,in the transformation of national economic development methods and the promotion of social harmony and civilized construction,the ecological carrying capacity of the urban fringe area will also play an important role that can not be ignored,providing a new research perspective for urban ecological construction.
Based on the SPOT5remote sensing image with a resolution of2.5m in2000,2006, 2012and2015and the land use data of Dalian,the Ganjingzi City of Dalian City was taken as an example to analyze the characteristics of spatio-temporal evolution of ecological carrying capacity in the urban fringe area.Drivers.The research results show that:(1)In the

process of urban land use evolution in Ganjingzi District,the urban land use types have expanded spatially over a large area,and the temporal evolution has been characterized by rapid growth and slow growth;the urbanization of Ganjingzi District has also shown rapid development.After the slow characteristics;community Theil index gradually increased.(2) In the temporal and spatial evolution characteristics of urban ecological carrying capacity,the pattern of time expansion and spatial expansion coexisted.Analysis of spatial-temporal evolution characteristics of urban ecological carrying capacity ranks:The spatial evolution of urban ecological carrying capacity:The spatial distribution of ecological carrying capacity of Ganjingzi District shows the characteristics of obvious differences in the eastern and western regions,similar levels interspersed,and the same level of small-scale accumulation.Time evolution of urban ecological carrying capacity:From2000to2006,the highest value of urban ecological carrying capacity was the highest,indicating that the degree of deterioration of ecological carrying capacity was largest from2000to2006,and the lowest value of urban ecological carrying capacity evolution was also the lowest,indicating the ecological carrying capacity from2000to2006.The degree of recovery is also higher than other periods.(3)In the mechanism research,taking the natural factors and the evolution of urban green space as internal driving factors,social factors,economic factors and urban traffic factors as the external driving force have become the main driving force for the evolution of ecological carrying capacity in urban fringe areas.On the basis of in-depth study of the evolution mechanism of ecological carrying capacity,we will better promote the development and construction of ecological planning in urban fringe areas.

1.1研究背景与意义
1.1.1研究背景
（1）城市生态承载力成为研究热点
承载力是生态学研究中的一项重要指标，它反映生物与其生存环境之间的承压关系，衡量自然环境容纳生物生存能力或自然界承受生物生存压力弹性的限度[1-2]。在21世纪，城市作为一个复合生态系统，不仅从土地利用、气候、生物多样性等方面对人类产生影响，更已经成为人类物质生产和精神活动的中心[3]。随着城市规模和城市人口的迅速增加，城市对于人类的未来发展将起到至关重要的作用[4]。因此，系统的分析城市不同区域上的土地利用和土地覆盖，协调发展与生态承载力之间的关系对城市社会建设发展有着积极的现实意义[5-6]。城市生态承载力问题也成为城市生态问题研究中的重点之一。
（2）城市边缘区生态问题是城市化发展过程亟待解决的问题
伴随我国城市化进程的不断推进,城市功能空间不断外溢，从而衍生出一个城市和乡村相复合的地域——城市边缘区[7]。城市边缘区作为城相结合区和城市扩展区，在城市发展过程中，城市边缘区的土地利用结构、产业结构、人口结构、社会经济结构等都逐渐发生转变[8]。城市边缘区土地利用方式多样,空间景观形态不一，各种错综复杂的关系使之成为城市空间扩展以及生态环境矛盾最为突出的地区。解决城市边缘区生态承载力与城市化建设扩张之间的关系问题，是目前城市边缘区实现生态环境与人类发展协调发展亟待解决的问题[9]。
1.1.2研究意义
（1）理论意义
①拓展了城市生态承载力研究的视角
文章以城市生态承载力理论为基础，通过城市地理学、自然地理学、人居环境学等不同的研究视角对城市生态承载力的定义和表现进行了探索，并以大连市甘井子区为例进行分析，丰富了城市边缘区生态承载力的研究，扩大了城市边缘区生态问题的研究视角，更适应中国的城市化发展现状。
②丰富了城市生态承载力的研究方法
现有的有关城市生态承载力的研究在中国多数是针对不同的城市类型，从不同的研究对象出发研究资源型城市、农业生产型城市、工矿业类型城市、社会经济快速发展型城市、以及面临产业转移的城市等各种类型城市，解决生态承载力与城市发展之间的协调发展问题，而缺乏从时空分异特征和驱动因素的方面，对小尺度典型研究区域进行城市生态承载力时空演变特征分析。本文以大连市的城市边缘区甘井子区为例，通过对城
