【摘要】：目的定量分析陕西省地形与城镇空间格局的特征,阐明二者之间的内在联系。方法以GIS为主要技术,以地形起伏度为主要指标,使用区域分析法、统计分析法和相关系数法进行分析。结果1)陕西省的地形起伏度在0.091~4.274的范围内,整体态势为南比北高,西比东高。2)陕西省的城镇大多分布在地形起伏度低于1的较为平坦地区。3)地形起伏度与人口密度的拟合曲线为指数形式,相关系数为-0.81,呈现显著负相关。4)陕西省地形起伏度与GDP的相关性不明显,地形条件对经济的影响日趋减弱。结论地形对城镇体系的分布起着至关重要的作用,新型城镇化战略往往是从地形起伏小和最佳区位条件处开始孕育和发展的。
[Abstract]:Objective to quantitatively analyze the characteristics of terrain and urban spatial pattern in Shaanxi Province, and to clarify the internal relationship between them. Methods using GIS as the main technique and terrain fluctuation as the main index, the regional analysis method is used. The results of statistical analysis and correlation coefficient analysis are as follows: 1) the relief degree of Shaanxi Province is in the range of 0.091 ~ 4.274, and the whole situation is higher in the south than in the north. The fitting curve between topographic fluctuation and population density is exponential form. The correlation coefficient is -0.81, showing a significant negative correlation .4) the correlation between terrain fluctuation and GDP is not obvious in Shaanxi Province, and the influence of terrain condition on economy is weakening day by day. Conclusion terrain plays an important role in the distribution of urban system. The new urbanization strategy often starts from the terrain undulation small and the best location condition place place place to begin to breed and develop.
