【摘要】：土地是社会经济发展的基础,是人类生存的空间载体。我国虽然拥有的土地资源总量比较大,但由于人口众多,加之长期以来的粗放利用,使得我国的人地矛盾非常突出。土地资源的不可再生性和数量有限性决定了我国必须走集约利用的道路。从十七届三中全会第一次把节约集约用地定位为基本国策到十八届三中全会的健全土地节约集约使用制度;从中央城镇化会议上对节约集约利用土地问题做的重要阐释到农村工作会议上再次强调要节约集约用地,尽量少占或不占良田,再到2014年6月25日把“节约集约利用土地,转变土地利用方式”确定为宣传主题,无不彰显了节约集约用地的重要性和必要性。本文在阐明耕地集约利用的研究意义和国内外研究现状,深入理解耕地集约利用内涵和相关理论的基础上,通过耕地集约利用影响因素分析,结合巴中市巴州区耕地利用现状,基于“压力-状态-响应”(PSR)模型构建了耕地集约利用综合评价指标体系,运用层次分析法确定各指标的权重;进而计算出了巴州区2003-2010年耕地集约利用综合评价值,依据评价结果,提出了促进巴州区耕地集约利用的合理化建议。研究表明:从2003-2010年,巴州区耕地集约利用水平总体趋势是在波动中呈现上升。主要分为两个阶段,2003-2005年为第一阶段,该阶段耕地的集约度是在稳定中出现略微下降;2005-2010年为第二阶段,此阶段耕地的集约度增长幅度较大,除2008年和2010年集约度降低外,其余年份都有不同程度地增加。2003-2010年耕地集约利用度的总排序为:2009年2007年2010年2008年2006年2003年2004年2005年,年平均集约度为0.4393,属于中等集约利用水平。
[Abstract]:Land is the foundation of social and economic development and the space carrier of human existence. Although the total amount of land resources in our country is relatively large, because of the large population and extensive utilization for a long time, the contradiction between people and land in our country is very prominent. The non-reproducibility and limited quantity of land resources determine that our country must take the road of intensive utilization. From the third Plenary session of the 17th Central Committee of the first time to the conservation of intensive land use as the basic national policy to the third Plenary session of the 18th Central Committee of the sound land conservation intensive use system; From the important interpretation made at the Central urbanization Conference on the issue of land conservation and intensive use, to the rural work conference, which once again stressed the need to conserve intensive land use, to occupy as little or no good land as possible, and to "economize intensive use of land" by 25 June 2014, The change of land use mode "is determined as the propaganda theme, which shows the importance and necessity of saving intensive land." On the basis of expounding the significance of intensive use of cultivated land and the present research situation at home and abroad, and deeply understanding the intension and related theory of intensive utilization of cultivated land, this paper analyzes the influencing factors of intensive utilization of cultivated land, and combines with the present situation of cultivated land utilization in Bazhou District of Bazhong City. Based on the "pressure-state-response" model, the comprehensive evaluation index system of cultivated land intensive utilization is constructed, and the weight of each index is determined by AHP, and the comprehensive evaluation value of cultivated land intensive utilization in Bazhou district from 2003 to 2010 is calculated. According to the evaluation results, the rational suggestions for promoting intensive utilization of cultivated land in Bazhou district are put forward. The results show that from 2003 to 2010, the general trend of intensive use of cultivated land in Bazhou district is rising in fluctuation. The first stage is mainly divided into two stages: 2003-2005, in which the intensity of cultivated land decreases slightly in the stabilization period and the second stage in 2005-2010. The increase of the intensive degree of cultivated land in this stage is relatively large, except for the decrease of the intensive degree in 2008 and 2010. The total order of cultivated land intensive utilization between 2003 and 2010 in other years is: 2009, 2007, 2010, 2008, 2006, 2004, 2005, with an average annual intensity of 0.4393, which belongs to the level of moderate intensive utilization.
