Study on Distribution Characteristics of Industrial Population in Wumeng Mountain Area Based on Topographic Fluctuation

Abstract

Abstract: Industrial poverty alleviation is an important way to get rid of poverty in poor mountain areas. Understanding the topographic relief characteristics ofWumeng Mountain area and the distribution of industrial population can bring reference to the implementation of precision industry poverty alleviation. Based on the DEM data of 90m resolution ofWumeng Mountain area and the census data of industrial census in 2010,the best statistical window of terrain fluctuation is determined by mean change point method and the regional topographic undulation is extracted,combined with industrial population density and industrial population concentration index. The topographical relief ofWumeng Mountain area and the gathering of the industrial population reveals the intrinsic link between the two. The study draws the following conclusions:(1) The topographic relief ofWumeng Mountain area is dominated by small rolling hills and hills. The overall topographic relief is decreasing from the northwest to the southeast,and the central and eastern plains and terraces are quite wide. (2) The industrial population ofWumeng Mountain area is dominated by agricultural population,and its density is the highest in all industries; the concentration of Liangshan is the lowest in all industries,and the concentration of population in each region with better regional economic development is higher. (3) In Wunmeng Mountain area the population of the primary industry has the greatest correlation with the topographical relief, followed by the tertiary industry population,and the least relevant is the secondary industry; the small rolling hills are the comprehensive development zones and are the primary activity areas of the primary industry,hills and The layout of the second and third industries in the following regions is relatively reasonable,and it is advisable to protect and moderately develop tourism in the high and low mountains.

Key words: topographic relief, industrial population distribution, industrial poverty alleviation, Wumeng Mountain area
