| 中文摘要: |
| 运用计量统计和GIS 空间分析法，对2004—2014 年长江中游城市群各地市农业经济的时空差
异特征进行分析，结果表明：（1）2004—2014 年，长江中游城市群各地市农业经济绝对差异和相对差异均
呈逐步扩大的趋势；（2）农业经济发展水平在空间上从“西高东低”的空间特征逐渐演变为“西北至东南
逐渐降低的阶梯状”空间格局，且具有典型的“核心- 边缘”特征；（3）2004—2014 年各地市农业经济空
间差距总体呈缩小的趋势，其发展水平由次发达和欠发达地区为主的橄榄型结构向全面平衡过渡；（4）农
业经济空间集聚特征区域差异明显，并渐趋稳定，表现为由西部HH 集聚向东部LL 集聚变化的特征，逐步
演化为由东北HH 集聚向西南LL 集聚变化的空间格局，HH 空间集聚特征主要分布在东北部襄阳、宜昌、
荆门一带，LL 空间集聚特征主要集中在东南部上饶、南昌、景德镇一带；（5）自然因素中耕地面积是影响
农业经济发展的内在因素，而人口数量、农业机械动力、GDP、固定资产投资等是影响农业经济空间差异的
外在推手。 |
| 英文摘要: |
| By measurement statistics and GIS spatial analysis，the spatial-temporal differences in agricultural
economy of urban agglomeration in the middle reaches of the Yangtze River from 2004-2014 were analyzed. The
results showed that，during 2004-2014，the absolute difference and relative difference of agricultural economy in
the city of the Yangtze River middle reaches urban agglomeration expanded. The development level of agricultural
economy was from“ west to east” to“ northwest to southeast gradually reduced stepwise” in space and had a typical
“core - periphery” feature. During 2004-2014，agricultural economy in all regions of space gap was narrowing
overall. The level of development was from the“ less developed” and“ underdeveloped” area-based，which like oliveshape
structural to overall balance of transition. The regional differences of agricultural economy spatial agglomeration were significant and gradually stabilized；the spatial pattern of performance was characterized by“ the west HH to the
east LL agglomeration”，and gradually evolved into“ from northeast HH to southwest LL agglomeration”. HH spatial
agglomeration characteristics were mainly distributed in the Northeast，such as Xiangyang，Yichang，Jingmen. LL
spatial agglomeration characteristics were mainly concentrated in the Southeast，such as Shangrao，Nanchang，
Jingdezhen. Agricultural machinery power and arable land were inherent natural factors，which influenced the
development of agricultural economy. The per capita GDP，investment intensity and population density were external
promoter，which affected agricultural economic disparities. |
