【摘要】：交通在區(qū)域發(fā)展中起著基礎(chǔ)和支撐作用。以云南省為研究地域,以縣域為基本研究單元,以2002、2008、2012年為時間截點,以交通網(wǎng)絡(luò)密度、重要交通設(shè)施鄰近度、區(qū)位優(yōu)勢度三個指標集成交通優(yōu)勢度評價體系,運用緩沖區(qū)等GIS技術(shù)定量評價云南省縣域交通優(yōu)勢度的空間分布格局和時間變化特征。研究結(jié)果表明,(1)云南省交通優(yōu)勢度總體偏低,多數(shù)縣域的交通優(yōu)勢較弱,交通設(shè)施對云南區(qū)域發(fā)展的支撐能力和保障水平偏低。(2)云南省交通優(yōu)勢度的空間差異明顯。首先,“中心—外圍”分布格局明顯,以滇中城市群為中心,向周圍地區(qū)遞減;其次,以“云嶺—元江谷地”一線為界,東西地帶性差異突出,東部云南高原交通優(yōu)勢度明顯高于西部橫斷山脈及其余脈地區(qū);再次,滇中城市群地區(qū)交通優(yōu)勢度突出,交通設(shè)施對這些區(qū)域發(fā)展的支撐能力和保障水平較高,而省際邊界地區(qū)特別是滇西北地區(qū)交通優(yōu)勢度極低,交通設(shè)施對區(qū)域發(fā)展的支撐能力較弱,個(舊)開(遠)蒙(自)城鎮(zhèn)群、大理市、曲靖市的交通優(yōu)勢在全省相對明顯;此外,州市行政中心的交通優(yōu)勢度較高。(3)近10年來,云南省交通優(yōu)勢度的總體格局基本不變,但區(qū)域差異在增大。最后對云南省交通優(yōu)勢度的成因進行分析,提出交通發(fā)展建議。
[Abstract]:Traffic plays a fundamental and supporting role in regional development. Taking Yunnan Province as the research area, taking the county area as the basic research unit, taking the 2002 / 2008 and 2012 as the time cut-off points, integrating the traffic superiority evaluation system with the traffic network density, the proximity degree of the important transportation facilities and the location advantage degree. The spatial distribution pattern and temporal variation characteristics of county traffic dominance in Yunnan Province were quantitatively evaluated by using GIS techniques such as buffer zone. The results show that: (1) the degree of traffic dominance in Yunnan is on the low side, the traffic superiority in most counties is relatively weak, and the supporting capacity and support level of traffic facilities to the regional development of Yunnan are on the low side. (2) the spatial difference of traffic dominance in Yunnan Province is obvious. Firstly, the distribution pattern of "center-periphery" is obvious, taking the urban agglomeration in central Yunnan as the center, decreasing to the surrounding area; secondly, taking the "Yunling-Yuanjiang valley" as the boundary, the difference between the east and west zones is prominent. The traffic dominance degree of the eastern Yunnan plateau is obviously higher than that of the western Hengduan mountain range and its remaining veins. Thirdly, the traffic dominance degree of the central Yunnan urban agglomeration area is prominent, and the traffic facilities have a higher supporting capacity and guarantee level to the development of these regions. However, the interprovincial border area, especially in the northwest of Yunnan, has a very low degree of traffic dominance, and the traffic facilities have a weak supporting capacity to the regional development. The traffic advantages of the old (old) Kaikai (far) Mongolia (self) town group, Dali City and Qujing City are relatively obvious in the whole province. In addition, the traffic dominance degree of the administrative center of the city is higher. (3) in the last 10 years, the overall pattern of the traffic dominance degree in Yunnan Province is basically unchanged, but the regional difference is increasing. Finally, the causes of traffic dominance in Yunnan Province are analyzed, and suggestions for traffic development are put forward.
