摘 要:陕北黄土高原土地利用变化与经济发展之间相互作用关系十分复杂。通过回归分析和典型相关分析法对本区土地利用变化与经济发展之间的耦合关系进行了分析。1988-2004年陕北土地利用变化的总体特征是农用地和未利用地减少,建设用地增加。回归分析结果表明:土地利用变化与主要经济发展指标之间具有明确的函数耦合规律;土地利用结构变化与三次产业结构演变之间相关性达0.976,林地和建设用地比重的变化通过影响第二产业的比重,从而影响三次产业结构。林地和园地、耕地比重变化直接影响种植业在农业结构中的比重,从而影响农业结构,相关性分别达0.918和0.788。There exist very complicated interactions between land use change and economic development in northern Shaanxi Province of Loess Plateau.The coupling relationships between land use change and economic development were analyzed by applying methods of Regression Analysis and Canonical Correlation Analysis.From 1988 to 2004,land use dramatically changed in region.Agricultural land and un-used land area were decreased,but construction land increased.There were obvious coupling relationships between land use change and economic development in periods of study duration.The land use structural changes strongly influenced the industrial structure's development;the correlation coefficient was 0.976 between them.The forest and anstruction land influenced the secondary industrial proportion in total industry,and further influenced whole industrial structure.The structural changes of forest,orchard and arable land also directly influenced cultivated land in agriculture,affected agricultural department's structure.The correlation coefficient between the forest area and the crop cultivation income in total agriculture reached 0.918,and also is up to 0.788 between the orchard,arable land areas and the crop cultivation income.
