【摘要】：通達性發(fā)育及其演化的根本動力是城鄉(xiāng)社會經(jīng)濟—資源環(huán)境系統(tǒng)(SERE)要素非線性關(guān)聯(lián)作用的結(jié)果。針對傳統(tǒng)最短路徑通達性模型的缺陷及研究視角的狹隘,本文基于2000年~2014年荊州市道路網(wǎng)空間數(shù)據(jù)庫,重構(gòu)最短通行時間通達性模型,定量刻畫荊州市鄉(xiāng)鎮(zhèn)綜合通達性的時空演化格局,并從區(qū)域交通與社會經(jīng)濟資源環(huán)境要素耦合的視角,引入耦合協(xié)調(diào)度模型,揭示鄉(xiāng)鎮(zhèn)綜合通達性演化的非線性機理,研究表明:(1)荊州市鄉(xiāng)鎮(zhèn)綜合通達性發(fā)育良好,基本呈正態(tài)分布,表現(xiàn)出一定的隨機性;(2)中心區(qū)位偏好、荊江"天塹"作用、快速干道建設(shè),共同引致荊州市鄉(xiāng)鎮(zhèn)綜合通達性圍繞市域中心呈不規(guī)則的圈層分布;(3)鄉(xiāng)鎮(zhèn)綜合通達性與其SERE系統(tǒng)耦合協(xié)調(diào)度全局呈弱空間正相關(guān),但局域空間相關(guān)作用復(fù)雜,四種基本類型呈"抱團"分布;(4)鄉(xiāng)鎮(zhèn)綜合通達性與其SERE系統(tǒng)耦合協(xié)調(diào)度雖持續(xù)優(yōu)化,但存在明顯的交通滯后性發(fā)展,同時空間分異明顯,整體呈高耦合度——低協(xié)調(diào)度的異配性特征。
[Abstract]:The fundamental motive force for the development and evolution of accessibility is the result of nonlinear correlation between urban and rural socio-economic and resource environment system (SERE) elements. In view of the defects of the traditional shortest path accessibility model and the narrow research perspective, Based on the spatial database of Jingzhou road network from 2000 to 2014, this paper reconstructs the shortest time accessibility model and quantitatively describes the space-time evolution pattern of comprehensive accessibility in Jingzhou. From the perspective of coupling of regional traffic and social economic resources and environmental factors, the coupling coordination degree model is introduced to reveal the nonlinear mechanism of the evolution of township comprehensive accessibility. The study shows that the comprehensive accessibility of Jingzhou is well developed. Basically showing a normal distribution, showing a certain randomness in the central area preference, Jingjiang "natural cutting" role, rapid construction of the main road, The result is that the comprehensive accessibility of the towns in Jingzhou City is irregularly distributed around the center of the city. The comprehensive accessibility of the villages and towns is positively correlated with the overall degree of coupling and coordination of the SERE system, but the role of the local spatial correlation is complex. Although the coupling and coordination degree between the integrated accessibility and the SERE system of the villages and towns is optimized continuously, there is obvious development of the traffic lag, and the spatial differentiation is obvious at the same time. The whole is characterized by high coupling degree and low coordination degree.
