摘　　要：本研究基于遥感卫星影像,获取江苏省监测区内2015年和2019年水稻种植的空间分布信息,分析监测区内水稻种植面积变化程度、变化模式以及变化位置。结果表明,至2019年,监测区内90.7%的水稻田仍为水稻田,9.3%的水稻田调减为非水稻田,与2015年相比,监测区内水稻面积总计减少5.7%。在调减的水稻面积中,调减为水产养殖的占29.7%,调减为水生作物的占18.3%,调减为其他作物的占52.0%。调减幅度和调减模式具有很强的地域特征,水稻面积减少幅度大于10.1%的图幅框集中分布于里下河农区,减少幅度小于5.0%的图幅框集中分布于徐淮农区。针对监测区内3种调减模式,徐淮农区占比最大的是水稻→其他作物,其次是水稻→水生作物,最少的是水稻→水产养殖;里下河农区占比最大的是水稻→水产养殖,其次是水稻→水生作物,最少的是水稻→其他作物。Based on the remote sensing satellite images,spatial distribution of rice planting in the monitoring area of Jiangsu province in 2015 and 2019 was obtained,and the changes of position and pattern in rice planting areas were analyzed.The monitoring results showed that 90.7%of the rice planting fields in the monitoring area were still rice planting fields in 2019,while the rest 9.3%of the rice planting fields had been changed.The area of rice planting in 2019 reduced by 5.7%compared with that in 2015.Aquaculture accounted for 29.7%of the reduced rice planting area,aquatic crops accounted for 18.3%,and other crops accounted for 52.0%.The reduction range and mode had strong regional characteristics.The area with a decrease of more than 10.1%was concentrated in the agricultural area of Lixiahe,and the area with a decrease of less than 5.0%was concentrated in the agricultural area of Xuhuai.The proportion of aquaculture in the reduced rice planting area was largest in Lixiahe agricultural area,followed by aquatic crops,and the least was other crops.Other crops accounted for the largest proportion in Xuhuai agricultural area,followed by aquatic crops,and the least was aquaculture.
