中文摘要:
      在介绍陕西省城市化水平与耕地资源动态趋势的基础上,采用相关性理论对陕西省城市化水平与耕地面积变化之间的关系进行分析,借鉴协和度模型分析了1980—2010年陕西省不同阶段的城市化与耕地面积的协同度。研究结果表明:陕西省的耕地面积呈不断减少的趋势,城市化水平每增加一个单位,耕地面积就会减少6.318个单位,城市化水平的增加和耕地面积的不断减少表现出由负面效应到正面效应的转变,陕西省城市化水平与耕地资源的协调度表现出一定的阶段性特征,总体呈现出“勉强调和与基本调和—不协调—调和、基本协调与较协调”等3个阶段。
英文摘要:
      On the basis of the introduction of the level of urbanization and the dynamic trend of arable land resources in Shaanxi Province, this thesis analysed the relationship between the level of urbanization in Shaanxi Province and the change of cultivated land by the correlation theory. And it also analysed the synergy degree of urbanization and arable land at different stages of Shaanxi Province from 1980 to 2010 drawing lessons from the Concorde degree model. The study showed that the cultivated land in Shaanxi Province had showed a declining trend, for every unit increase in the level of urbanization, the arable land will be reduced by 6.318 units. The increase in the level of urbanization and dwindling of arable land shows the transition from the negative effect to the positive effect. The coordination between the level of urbanization in Shaanxi Province and the arable land resources exhibits periodic characteristics, overall showing the three stages of "barely coordinate and basically coordinate - incoordinate – coordinate, basic ally coordinate and comparatively coordinate".
