基于地理信息系统的青年男子短跑成绩与地理因素相关分析与评价——以陕西省为例

摘要

运用相关分析、主成分分析和系统聚类分析等方法,选取平均气温、气压、纬度、海拔等9项自然地理指标以及国内生产总值、人口总数、恩格尔系数、基尼系数4项人文地理指标,对1988—2009年陕西省青少年田径比赛短跑成绩进行分析处理,确立了各因素与运动成绩间关系的密切程度,并将陕西省适宜开展男子短跑项目的地区分为3类.结果表明：在0.01的置信度水平下,青年男子短跑成绩与相对湿度、降水量、国内生产总值、恩格尔系数、基尼系数呈现较高的相关性;西安为最适宜开展男子短跑项目地区,其次为咸阳、宝鸡、榆林、延安.%This article used correlation and principal components analysis methods,selects the average temperature,the frost-free period,the precipitation,the latitude,total nine physical geography target,GDP,the gross population,the Engel′s coefficient,the Gini′s coefficient four human geography target,collected 1988-2009 year of Shaanxi Province young people track and field competition results,established the close degree between various factors and the movement results,used the system cluster to divide area into three suitable kinds;and calculated composite index which means being suitable to develop the young man sprint project.
