宁夏农业现代化水平格局演变及空间分异

The Pattern Evolution and Spatial Distribution of Agricultural Modernization Level in Ningxia Hui Autonomus Region

农业现代化是"四化"协调发展的核心问题,研究农业现代化水平格局演变和空间分异对协调"四化"发展和区域发展具有重要意义。文章基于2001—2013年宁夏农业现代化相关数据,以宁夏19县市为基本研究单元,采用综合指数法和相对发展率研究宁夏农业现代化水平格局演变和空间分异。结果表明:(1)宁夏农业现代化水平总体发展趋势呈上升状态,19县市农业现代化水平呈交替上升状态,等级格局变动明显;(2)研究基期农业现代化综合指数较低的海原县、泾源县、彭阳县等县市相对发展率较高,但是到研究期末其农业现代化水平仍然处于区域最末水平;(3)宁夏农业现代化水平空间分异明显,呈现"北高南低"的分布态势,与宁夏自然地理分区呈现出明显的耦合性。

The modernization of agricultural is the key one of the coordinated development‘the four-modernization＇.It has great significance of coordinating development of the‘four-modernization＇and regional development to study the pattern evolution and spatial distribution of the agricultural modernization level.Based on Ningxia agricultural related data from 2001 to 2013,we selected 19 counties in Ningxia as the basic research units,and used the comprehensive index method and relative development rates to study the pattern evolution and spatial distribution of Ningxia agricultural modernization level.The results indicated that the overall trend of Ningxia agricultural modernization level was rising,but the scores of the 19 counties in Ningxia increased dramatically and pattern changed significantly;Haiyuan County,Jingyuan County and Pengyang County had the high relative development rate due to the low score of agricultural modernization at the base,but they still had the lowest score of Ningxia at the end of the study period.Ningxia agricultural modernization level presents obvious spatial distribution,showing apattern of high level in the north and low level in the south and obvious coupling with the natural geographical partition.
