【摘要】：改革开放30多年来,沈阳城乡快速发展,但农村地区发展速度明显比城市地区慢,中心城区扩张速度快,造成土地利用的效率降低,“半城镇化”、“农村空心化”等问题日益凸显,因此,沈阳城市和农村土地利用结构和布局的优化研究对于地区城乡建设协调发展具有重要指导意义。本文以沈阳市为研究对象,利用定性与定量分析方法、GIS空间分析方法等相关的分析方法,通过研究沈阳市1986-2016年城乡建设用地结构和布局,为沈阳市经济社会快速发展提供科学建议和政策保障。论文的主要内容包括:1986-2000年,城乡建设用地增加169.78 km2,其中城市、乡村建设用地分别占28%、72%;2000-2016年,城乡建设用地增加151.63 km2,其中城市、乡村建设用地分别占71%、29%,呈现出显著的阶段差异性;对沈阳市城市扩张特征进行研究分析。运用GIS空间分析中的缓冲区分析和空间方位分析等方法。得出苏家屯区、于洪区、东陵区和沈北新区分别在1986年到2000年和2000年到2016年间城市和农村居民点用地扩展的速度和区域性差异显著;自城市中心向外围,城乡用地扩张强度指数先增加后降低,约在12 km处呈现峰值;1986-2016年,沈阳市人口城镇化与土地城镇化经历了严重失调—重度失调—严重失调—极度失调—轻度失调的过程,这说明沈阳市人口城镇化与土地城镇化一直处于波动状态,虽然从2010年后的离差系数看,失调程度有所下降,但是沈阳市人口城镇化与土地城镇化失调情况还是非常严重的;沈阳市城乡建设用地系统的协调度整体水平比较低,至2016年协调度整体水平仍然比较低。深入分析后的结果显示:在很大程度上,通过城乡建设用地协调发展带来的城镇建设用地增加所伴随的农村居民点用地减少的土地面积极少。
[Abstract]:Over the past 30 years of reform and opening up, Shenyang has developed rapidly in urban and rural areas, but the development of rural areas is obviously slower than that of urban areas, and the expansion rate of central urban areas is faster, resulting in a decrease in the efficiency of land use, "semi-urbanization" and "hollowing out in rural areas" and so on. Therefore, the optimization of urban and rural land use structure and layout in Shenyang is of great significance to the coordinated development of urban and rural areas. By using the qualitative and quantitative analysis method and GIS spatial analysis method, this paper studies the structure and layout of urban and rural construction land in Shenyang from 1986 to 2016. The main contents of this paper include: from 1986 to 2000, the number of urban and rural construction land increased by 169.78 km ~ 2, among which urban and rural construction land accounted for 28% from 2000 to 2016. Urban and rural construction land increased by 151.63 km ~ (2), among which urban and rural construction land accounted for 71 / 29 respectively, showing significant stage difference; The characteristics of urban expansion in Shenyang are studied and analyzed. By using the methods of buffer analysis and spatial azimuth analysis in GIS spatial analysis, it is concluded that Sujiatun district, flood area, etc. From 1986 to 2000 and 2000 to 2016, the speed and regional difference of urban and rural residential land expansion in Dongling District and Shenbei New District were significant, and the intensity index of urban and rural land expansion first increased and then decreased from the urban center to the periphery. During the period 1986-2016, the population urbanization and land urbanization in Shenyang experienced a process of serious maladjustment, severe maladjustment, severe maladjustment, extreme maladjustment and slight maladjustment. This shows that population urbanization and land urbanization in Shenyang has been in a state of fluctuation, although the deviation coefficient after 2010, the degree of imbalance has decreased, but the imbalance between population urbanization and land urbanization in Shenyang is still very serious; The overall level of coordination of urban and rural construction land system in Shenyang is relatively low, and by 2016, the overall level of coordination degree is still relatively low. The results of in-depth analysis show that: to a large extent, Through the coordinated development of urban and rural construction land, the increase of urban construction land is accompanied by the decrease of rural residential land area.
