县域土地利用中建设用地增长及其影响因素——以辽宁省建昌县为例

以辽宁省建昌县为研究对象,对2000—2010年建昌县建设用地的变化和利用效率进行了分析,选取建设用地和社会因素、经济因素建立相关关系模型,分析相关系数并得出结论:与全国土地利用变化态势一致,建昌县建设用地逐年增长;促使其变化的影响因素主要有人口、GDP、城镇化水平、固定资产投资以及第二、第三产业产值,总体上这与大多数城市类似;今后几年建昌县建设用地总量仍然会持续增长,土地供需矛盾将日益加剧,这给耕地保护任务带来了巨大压力,有效协调县域土地利用中经济建设和生态环境、耕地保护的关系迫在眉睫。

On the Expansion of Construction Land in County Land Use and its Influencing Factors-- A Case Study of Jianchang County in Liaoning Province

This paper selects Jianchang which belongs to Liaoning province as the research object and analysis its change and efficiency of construction land from 2000 to 2010.Construction land and social factors,economic factors are selected to establish the relation model,and correlation coefficient is analyzed to conclude that: consistented with the change trend of the national land use,construction land of Jianchang is increasing year by year;main influence factors of this change includes population,GDP,the level of urbanization,fixed asset investment and two,three industrial output value in general are similar with the most city;in the next few years,the total amount of land in Jianchang used for construction purposes will still continue to grow,and the contradiction between supply and demand of land will become increasingly severe,which bring the huge pressure to the cultivated land protection mission,so effective coherence with the relationship between economic development,ecological environment and the cultivated land protection in county land is imminent.
