四川省农业现代化发展的格局演化研究

A Sdudy on Pattern Evolution of Agricultural Modernization in Sichuan Province

通过构建农业现代化水平综合评价指标体系,运用熵值法对2005—2014年四川省21个市(州)地域单元的农业现代化发展水平进行测度,再运用空间自相关分析法探究农业现代化发展的时空演化规律.研究表明:在研究时间段内四川省农业现代化发展水平持续上升,地区差距有所减小;四川省的农业现代化水平整体表现出"中间高,四周低"的特点,农业现代化水平空间分布为HH型和HL型市域主要分布在成都平原地区,并向川南地区扩展;空间分布为LL型和LH型市域则集中在川西北、川西南、川东北的高原、山地、丘陵地区.自然条件基本决定了四川省农业现代化发展的总体格局,区位因素、农业基础设施、政府扶持和引导、农业科技水平、农村劳动力素质、交通等影响着四川省农业现代化发展的格局演变.

Through the construction of a comprehensive evaluation index system of agricultural modernization,the entropy method was used to measure the level of agricultural modernization of 21 urban（prefecture）regional units in Sichuan Province between 2005 and 2014,and then the spatial self-correlation analysis was done to investigate the temporal and spatial evolving law of agricultural modernization.It finds that：（1）During the studied period of time,the level of agricultural modernization in Sichuan Province undergoes a stead fast in crease,and the regional gap has been narrowed moderately.（2）The overall level of agricultural modernization in Sichuan Province is characterized by＂a high middle with low periphery＂.The HH and HL horizontal distribution of agricultural modernization is chiefly concentrated in the Chengdu plain area and extended to southern Sichuan;the LL and LH-type spatial distribution is concentrated in the northwest,southwest of Sichuan,and northeastern Sichuan plateau,mountainous or hilly areas.Natural conditions basically determine the overall pattern of agricultural modernization.Regional factors,agricultural infrastructure,government support and guidance,agricultural science and technology level,rural labor quality,transportation and so on have all played a part in forming the evolution pattern of agricultural modernization in Sichuan Province.
