长三角典型农业区农业现代化水平分区研究——以江苏省兴化市为例

Zoning of Agricultural Modernization on A Typical Agricultural Area in the Yangtze River Delta:A Case Study of Xinghua City

采用因子分析方法,按照兴化市农业现代化水平评价指标体系,以乡镇为评价单元,分析各主因子的空间分布特征及影响因素。根据各主因子得分系数矩阵,采用分层聚类法把兴化市35个乡镇划分为5个农业现代化水平类型区,并对各类型区提出相应的农业发展策略。结果表明:兴化市农业现代化水平具有明显的空间集聚分布特征,以西部的昭阳镇为中心和以东南部戴南镇为中心的区域农业现代化水平程度最高;较高农业现代化水平的地区主要位于南部和东北部的安丰镇、永丰镇和戴窑镇;中等农业现代化水平的区域主要是兴化市区的卫星城镇;较低和低农业现代化水平的区域主要位于兴化市西北和东部,其中,位于西北部的周奋乡和缸顾乡农业现代化水平最低。

Referencing to the factorial analysis which is used in the studying urban social spatial structure, evaluation index system of agricultural modernization level in Xinghua City was established. Based on the villages and towns in Xinghua City as evaluation unit, the spatial distribution of the main factors and influence elements were analyzed. According to the main factor scores coefficient matrix, the 35 townships in Xinghua City were divid- ed into five classes of agricultural modernization by using hierarchical clustering, and put forward different agricultural development strategies for them. The results show that ： the level of agricultural modernization has obvious spatial agglomeration distribution in Xinghua City. The regions which center is Zhaoyang in the west and Dainan in the southeast have the highest level of agricultural modernization; the regions which have higher level of agricultural modernization are mainly located in south and northeast; the majority regions in medium level of agricultural mod- ernization are the satellite towns of Xinghua; low level of agricultural modernization areas are mainly located in the northwest and east of Xinghua City, in which Zhoufen and Ganggu Village in the northwest are the lowest level of agricultural modernization areas.
