| 摘 要： | 采用趋势分析法和回归分析法,剖析了黑龙江省耕地数量变化的驱动因子,研究了其变化机理.结果表明:黑龙江省经济增长与耕地递减呈明显线性负相关关系,社会经济发展因子是耕地减少的主要内在驱动力,经济利益和有关土地政策是引起耕地变化的外在驱动力,并指出保护耕地和确保粮食安全是土地管理工作的当务之急.

| Abstract: | The purpose of this study is to analyze the driving factors of cultivated land quantity variation and find its change mechanism in Heilongjiang Province.Methods of trend analysis and regressive analysis are employed.The results show that firstly a negative linear correlation between economic growth and the available cultivated land decreasing,secondly social economic development is the inner driving forces that caused cultivated land change,and finally economic benefit and land policies are exogenous driving forces.The conclusion is drawn that protecting cultivated land and insuring foodstuff security are very urgent in current land administration. |
