摘要
利用逐步回归分析建立了青海省共和县耕地利用变化的驱动力模型,利用多元统计分析中的通径分析、相关分析、偏向关分析和系统动力学的方法考察了影响耕地变化的驱动力在不同作用状况下的耕地变化情况,从县域规模水平上对土地利用变化的驱动因子及其作用机理和过程进行了分析,并提出了相应的政策措施。
Using gradually regression analysis to establish the driving force model of utilized change of cultivated land in Gonghe County, and using path analysis, correlation analysis, partial correlation analysis and system dynamics method to inspect the effect of driving changing on cultivated land change under different change situations. Driving factors, action mechanism and process of utilized change of cultivated land were analyzed from the county territory scale level. At last, some corresponding policies and measures were put forward.
