| 摘 要： | 以香格里拉县1974～2003年的人文社会经济统计数据和遥感影像为基础,选择10个与县域土地利用变化有关的指标,进行主成分分析与回归分析,进而从地理信息挖掘的层面上分析了研究区土地利用/土地覆被变化的人文驱动力。结果表明:在推动土地利用与土地覆被变化错综复杂的原动力影响中,人文因子对研究区土地利用与土地覆被的短期变化有重要影响,其中耕地数量与农业人口数、种植业产值、农业产值在工农业产值中的比重、社会商品零售总额以及财政收入呈负相关的关系;耕地数量与牲畜数量、农村人均收入、粮食总产量、耕地保护政策变量,呈负相关的关系。

| Abstract: | Based on the social-economical statistics data of Shangri-La County from 1974 to 2003,10 indicators related to land use/ land cover change (LUCC) in county level had been selected,principal components analysis and regression analysis had been conducted,then the humanistic driving forces of LUCC in Shangri-La County had been analyzed from the aspect of geographical information mining. The results showed that the humanistic factors are keys to LUCC during short periods in county level. And the amount of cultivated land was negatively correlated with the agriculture population,production value of plantation,the proportion of agriculture production value in industrial and agriculture production value,social goods retail amounts,and financial income. The amount of cultivated land was also negatively correlated with the number of livestock,per capita income of rural people,crop production and protective policy of cultivated land. |
