摘要: 产业扶贫是贫困山区脱贫的重要方式.了解乌蒙山区地形起伏特征与产业人口分布状况,可为精准产业脱贫的实施带来参考.基于乌蒙山区90m分辨率DEM数据和2010年分县产业人口普查数据,通过均值变点法确定地形起伏的最佳统计窗口并提取区域地形起伏度,结合产业人口密度和产业人口集中指数分析乌蒙山区地形起伏度与产业人口的聚散态势,并揭示二者内在联系.研究得出以下结论:(1)乌蒙山区地形起伏度以小起伏山地和丘陵为主,总体上地形起伏由西北部向东南递减,中东部平原和台地面积较广.(2)乌蒙山区产业人口整体以农业人口为主,其密度为各产业最高;大小凉山各产业人口集中度均为最低,区域经济发展较好地区各产业人口集中度均较高.(3)乌蒙山区第一产业人口与地形起伏度相关性最大,其次为第三产业人口,相关性最小的为第二产业;小起伏山地为综合发展区且同时是第一产业主要活动区,丘陵及以下区域第二、三产业布局较为合理,高起伏山地以保护和适度开发旅游为宜.

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
