It can have significant impact on regional productivity , life, infrastructure construction and other social economic development. Chongqing City is the only municipality directly under the central government in western part of China. Being reduced to fragments of terrain, the surface fluctuation degree here is rather high. The natural geographical environment, traffic conditions and the original basis for the development of the enormous differences within Chongqing City area result in the unbalanced regional economic development. Through the research on the correlation betwween the relief degree of land surface and the development of District economy, it is discovered that there is a certain correlation between social economic development indicators and the the surface fluctuation degree. Furthermore, with social and economic development, this correlation will be enhanced and obvious.These findings can not only help to understand the surface fluctuation condition in Chongqing City, from the macro aspects, but also provide some reference for the government to make the budget and transfer payment. key words: the surface fluctuation degree; the development of county economy; Relevance. 1 引言 具有“山城”之称的重庆市地处中国第二阶梯的前缘，区域地跨大巴山断褶带、川东褶皱带和川鄂湘隆起褶皱带三大构造单元，地形支离破碎，地表起伏程度较大。这种崎岖破碎的地表起伏状况极大的增加了重庆境内的生产、生活、基础设施建设和行政办公成本，降低了生产和基础设施投入产出效应，加大了财政运行难度。主要表现在： 地表起伏程度越大，在城市建设、交通水利等基础建设时桥隧比、土石方开挖、地基平整的工程量越大，学校、医
