Study on Optimization Structure of Urban and Rural Land Use in Changyang Tujia Autonomous County

根据长阳土家族自治县国民经济和土地利用现状数据,系统分析了1997-2005年该地区城乡建设用地结构现状,结果表明：1997-2004年长阳土家族自治县城乡建设用地面积呈逐年增加趋势,到2005年城乡建设用地面积明显下降。利用实地调查法、平均增长率法、定额指标法和灰色预测法等相关经济分析方法,对长阳土家族自治县2010、2020年城乡建设用地结构进行预测。针对城乡建设用地结构存在城镇用地规模偏小、农村居民点用地结构不合理以及土地利用率低等问题,提出了城乡建设用地结构优化建议措施。
