摘要
以江苏省农业统计资料为数据来源,利用区位基尼系数、集中率、平均地理集聚率以及局域空间相关性等指标,测算出江苏省粮食作物种植的地理集聚程度。静态考察发现1980年江苏省粮食作物种植总体上具有地理集聚特征,不同行业地理集聚的差异显著,多数地区具有中度地理集聚特征,一些行业具有连片化特征。动态考察发现1959—1980年江苏省粮食作物种植地理聚集整体表现为先降后升,不同行业的变动差异显著;空间上不同地区呈现一定的地理集聚特征,集聚程度的变动并不明显。这一时期江苏省粮食作物种植的地理集聚主要受传统农业种植结构、农业政策和农业技术进步因素的影响,其中传统农业种植结构是基础性因素。
Taking the agricultural statistics of Jiangsu Province as the data source,the geographical agglomeration degree of grain crop planting in Jiangsu Province is calculated by using the indicators such as location Gini coefficient,concentration rate,average geographical agglomeration rate and local spatial correlation.The static.investigation found that the grain crop planting in Jiangsu Province in 1980 generally had the characteristics of geographical a agglomeration,the geograp phical agglomeration of different industries had significant differences,most arcas had the characteristics of moderate geographical agglomeration,and some industries had the characteristics of contiguity.The dynamic investigation found that the overall performance of grain crop planting geographical ag lomeration in Jiangsu Province from 1959 to 1980 was first down and then up,and the changes in different industries were significantly different;Spatially,different regions show certain geographical agglomeration characteristics,and the change of agglomeration degree is not obvious.During this period,the geographical agglomeration of grain crop planting in Jiangsu Province was mainly affected by traditional agricultural planting structure,agricultural policy and agricultural technology progress,among which traditional agricultural planting structure was the basic factor.
