【摘要】：以江河源区为案例选取指标,通过相关性分析及建立影响缓冲区探究牧民收入与交通发展水平的关联性。结果表明:(1)到达中心城市的通达便利程度与收入水平之间呈滞后性显著相关,即到达中心城市越便捷的县域牧民收入相对较高;(2)2005年路网密度与收入微弱负相关,2011年打破总体密度过低的限制,两者相关系数达0.471,呈显著正相关,路网总密度中高等级公路贡献越大,越能发挥公路对牧民收入的促进效应;(3)2005年县乡道与收入关联性最强,2011年省道成为影响牧民收入的最关键等级道路,但目前各等级道路均处于较低建设水平;(4)2006年青藏铁路全线通车即刻发挥对周边县域的辐射影响,距铁路距离与收入之间呈显著负相关,并逐年增强,进一步建立缓冲区发现铁路300 km缓冲区以内县域收入明显高于300 km以外县域;(5)西宁机场300 km缓冲区内县域牧民收入明显高于其他县域,格尔木机场及玉树机场目前影响不显著,但未来潜力不可忽视,三大机场300 km缓冲区覆盖整个源区所有县域,最终带动牧民整体收入水平的提高。
[Abstract]:Taking the headwaters of the Yangtze River as a case study, the correlation between herdsmen's income and the level of traffic development is explored through the correlation analysis and establishment of the buffer zone.The results showed that there was a significant lag correlation between the accessibility to the central city and the income level.That is, the more convenient to reach the central city, the higher the income of the herdsmen in the county) in 2005, the road network density has a weak negative correlation with the income, and in 2011, the limit of the total density is too low, the correlation coefficient between the two is 0.471. there is a significant positive correlation between the road network density and the income.The higher the contribution of highway network to the total density of road network, the greater the contribution of highway to herdsmen's income. (3) the county and township roads have the strongest correlation with income in 2005, and the provincial roads in 2011 have become the most critical grade roads affecting herdsmen's income.However, at present, the roads of all grades are at a relatively low level of construction. In 2006, the whole Qinghai-Tibet Railway immediately brought into play the radiation effect on the surrounding counties. The distance from the railway to the railway has a significant negative correlation with the income, and it has increased year by year.Further establishment of buffer zone found that the income of county area within 300 km buffer zone was obviously higher than that of county area beyond 300 km.) the income of herdsmen in Xining airport 300 km buffer zone was obviously higher than that in other counties, but the influence of Golmud airport and Yushu airport was not significant at present.But the potential in the future can not be ignored. The 300 km buffer zone of the three airports covers all counties of the source area and eventually leads to the improvement of the overall income level of herdsmen.
