泛长三角地区农用地资源利用效率与空间格局分析

以泛长三角地区为例,运用修正DEA模型测度1999-2013年区域农用地资源利用效率值.通过ESDA模型分析了泛长三角地区农用地利用效率空间格局演变特征.结果表明：1999-2013年泛长三角地区农用地利用效率以提升为主要趋势,技术效率高于综合效率和规模效率,农用地利用总体表现出技术效率驱动模式.全局上,泛长三角地区农用地利用效率呈现出空间自相关,效率高（低）的城市空间表现集聚分布.局部上,效率H-H类型主要分布在苏锡沪地区,H-L类型主要集中在杭甬、宁镇及皖江地区,L-H类型主要集聚在苏中、皖南及浙西南地区,而L-L类型主要分布在苏北地区、皖北及皖西地区.最后,结合效率空间格局分析有针对性地提出未来泛长三角地区农用地利用的优化路径.

Agricultural Land Use Efficiency Assessment and Spatial Pattern Evolution in the Pan-Yangtze River Delta

This paper took the Pan-Yangtze River Delta as the research object, built up the agriculturalland use efficiency assessment index system, using DEA model to measure agricultural land use effieiency value from 1999 to 2013, and ESDA model to discuss agricultural land use efficiency spatialpattern. Results showed the following. From 1999 to 2013, agricultural land use efficiency was on therise, the efficiency of regional differences became increasingly significant, and technical efficiency washigher than comprehensive and scale efficiency. In addition, technological progress was the main driveand on the whole, agricultural land use efficiency presented spatial autocorrelation; the efficiency typeof H-H was mainly located in Suzhou-Wuxi-Shanghai, the efficiency type of H-I. was mainly situatedat Hangzhou-Ningbo, Nanjing-Zhenjiang and Wan Jiang region; the efficiency type of I.-H was mainlylocated in the middle of Jiangsu, the southern of Anhui and the southwest of Zhejiang; the efficiencytype of L-L was mainly in the northern Jiangsu and Anhui. Finally, based on the above analysis of theagricultural land use efficiency spatial pattern, an optimum path of future agricultural land use in thePan--Yangtze River Delta was pertinently proposed.
