摘    要:为了提高辽宁省的农业经济效益,以辽宁省为研究区域,以2001—2014 年农作物统计数据为数据源,运用数理统计和GIS 空间分析方法,分析辽宁省近14 年玉米、水稻、大豆、油料和蔬菜5 种主要粮食和经济作物播种面积的时间空间变化特征。结果表明:(1)2001—2014 年辽宁省农作物总种植面积增加16.97%,粮食作物和经济作物种植面积分别增加17.30%和15.85%,且粮食作物始终占农作物总种植面积的较大比例,大致为77.50%。(2)玉米种植面积大幅增加70.54%,种植比例逐年上升,水稻种植面积减少79.62%,油料作物种植面积增加33.4%,蔬菜种植面积增加14.73%,大豆种植面积大幅减少63.36%。增加的地区集中在沈阳、铁岭、锦州等辽宁中北部地区。(3)通过对辽宁省各市5 种主要农作物种植面积进行GIS 空间分析,发现其分布存在一定的空间集聚现象。玉米、水稻、油料和蔬菜的种植结构呈现出以沈阳为中心向西、北辐射的分布特点,大豆的种植区域主要集聚在大连和沈阳。

Temporal and Spatial Characteristics of Crop Planting Structure in Liaoning Province
Abstract:To improve the agricultural economic benefit of Liaoning Province, we take 2001-2014 statistical data of crops as the data source, used mathematical statistics and GIS spatial analysis method to analyze temporal and spatial variations of sown area of five major grain and economic crops including corn, rice, soybean, oil and vegetable. The results showed that (1) from 2001 to 2014, the total sown area of crop in Liaoning Province increased by 16.97%, and the sown area of grain crops and economic crops increased by 17.30% and 15.85% respectively, and grain crops always accounted for a large proportion of total crop cultivation area, approximately 77.50%; (2) the sown area of corn increased by 70.54%, the planting proportion increased year by year, the sown area of rice decreased by 79.62%, the sown area of oil crops increased by 33.4%, the sown area of vegetables increased by 14.73%, and the sown area of soybeans decreased by 63.36%, the increased areas concentrated in the central and northern regions of Liaoning, such as Shenyang, Tieling and Jinzhou; (3)through GIS spatial analysis of the sown area of five major crops in Liaoning Province, it was found that there was some spatial agglomeration in distribution, the planting structure of corn, rice, oil and vegetables showed a radiation distribution from Shenyang to the west and north, while the planting area of soybean mainly concentrated in Dalian and Shenyang.
