摘要
根据广西壮族自治区2005～2009年的统计资料,运用相关系数法分析了广西耕地动态变化过程,并选取广西总人口、人均GDP、社会固定资产投资、第二产业比重、第三产业比重等社会经济指标,定量分析了社会经济的发展对耕地面积变化的影响。结果表明,2005～2009年广西耕地面积在总体上呈减少趋势,社会经济的持续快速发展对这一时段耕地减少起着重要作用,但影响程度正在逐步降低,第三产业比重与耕地面积的相关性不大。
According to the statistical data of Guangxi Province from 2005 to 2009, the dynamic changes of Guangxi cultivated lands were an- alyzed with the method of correlation coefficient, and the impact of socio-economic development on the change of cultivated lands was quantita- tively analyzed with the indices of total Guangxi population, per capita GDP, social investment in fixed assets, proportion of the second and tertiary industry, etc.. As indicated by the results, the total cultivated area in Guangxi presented a decreasing trend from 2005 to 2009, the rapid development of society and economy produced significant influence on the decrease of cultivated lands, but the influential degree was gradually decreasing, and there was little correlation between the proportion of the tertiary industry and the cultivated lands.
