摘要
以1990—2019年的农业统计数据为数据源,采用空间数据分析法与数理统计分析法,探讨30年来江苏省农作物种植结构的时空分布及“非粮化”状况。结果表明,江苏省农作物种植面积近30年内不断下降,全省经济作物总播种面积在农作物总面积中的比重呈快速缩减趋势;苏北地区粮食作物播种面积保持逐渐增长态势,苏南地区“非粮化”趋势明显;小麦逐渐代替水稻成为江苏省播种面积最广的粮食作物,苏南地区水稻种植近10年来向苏中、苏北地区转移,玉米在南通市种植最广,大豆全省播种水平持续较低。江苏省种植类型逐渐多元化,已形成多类作物组合种植;粮食安全状况向好转变。
Based on the agricultural statistical data from 1990 to 2019,the temporal and spatial distribution and“non grain-oriented”situation of crop planting structure in Jiangsu Province in the past 30 years was discussed by using the methods of spatial data analysis and mathematical statistical analysis.The results showed that the planting area of crops in Jiangsu Province had been declining in recent 30 years,and the proportion of the total sown area of cash crops in the total area of crops in Jiangsu Province showed a rapid reduction trend.The sown area of grain crops in northern Jiangsu Province maintained a gradual growth trend,and the“non grain-oriented”trend in southern Jiangsu Province was obvious.Wheat had gradually replaced rice as the food crop with the widest sowing area in Jiangsu Province.Rice planting in southern Jiangsu Province has shifted to central and northern Jiangsu Province in recent 10 years.Corn was the most widely planted in Nantong City,and the sowing level of soybean in the whole province continued to be low.The planting types in Jiangsu were gradually diversified,and a combination of many kinds of crops had been formed.The food security situation had changed for the better.
