四川省城镇化与耕地资源变化关系及协调性分析

Analysis on relationship and coordination between urbanization and cultivated land resource change of Sichuan province

在分析1978—2011年四川省城镇化水平与耕地资源变化趋势的基础上,探讨了城镇化与耕地资源变化的理论关系与定量模型,并对两者协调关系进行了分析。研究结果表明:四川省城镇化水平不断提升的同时,耕地总面积与人均耕地面积呈整体减少趋势,并具有阶段性特征;理论框架下的城镇化与耕地资源协调发展难以实现,城镇化水平每增加1个单位,耕地面积相应减少5.743个单位;四川省城镇化与耕地资源变化协调度表现出阶段性特征,整体呈现出"基本调和、调和——勉强调和、不协调——基本协调、较协调"的状态趋势。在此基础上,提出城镇化与耕地资源协调发展的对策建议。

Based on the tendency analysis of urbanization level and cultivated land resource change from 1978 to 2011 of Sichuan province, the paper studied the theoretical relationship and quantitative model between urbanization and cultivated land resource change, and analyzed the coordination. Results showed： accompanied with the rising of urbanization level in Sichuan province, cultivated land total areas and per person area presented decreasing tendency which possessed stage characteristics; coordinated development between urbanization and cultivated land resource hardly realized under the theoretical framework, as cultivated land area would decrease 5.743 units if urbanization level promoted one unit; coordinated degree between urbanization and cultivated land resource change of Sichuan province showed stage characteristics which presented state of ＂basically coordinate and coordinate to barely coordinate and incoordinate to basically coordinate and comparatively coordinate＂. Based on these, the paper put forward suggestions on the coordinated development between urbanization and cultivated land resource.
