摘要:
选择农田防护林作为界定田块是否连片的标准，分析了水稻规模连片种植的时空格局及变化特征。结果表明，①2011-2019年， 研究区内0.67×103 hm2以上规模连片水稻种植面积逐年减少。其中， 6.67×103 hm2以上连片水稻种植面积平均减少7.38%， 3.34×103～6.67×103 hm2连片水稻种植面积平均减少2.40%，0.67×103～3.33×103 hm2连片水稻种植面积平均减少0.76%。②位于洪泽县，东海县、灌云县、连云港城区交界处，东海县的大于6.67×103 hm2连片水稻种植面积持续保持稳定；位于淮安市楚州区，滨海县、射阳县、阜宁县交界处，盐城市盐都区的大于6.67×103 hm2水稻连片区从大到小或从有到无，变化幅度较大。③随着水稻规模连片区的缩小，连片区内水稻种植逐步单一化、水稻田块空间分布紧密度提高。本研究提出的用田块间间距来界定田块是否连片的方法，能够有效解决区域性农作物规模连片种植的量化问题。
Abstract:
The farmland shelterbelts were chosen as the criterion for determining whether the fields were contiguous or not to analyze the spatiotemporal pattern and variation characteristics of rice planted on a large scale contiguously. The results showed that, firstly, from 2011 to 2019, the area of the contiguously planted rice with a scale above 0.67×103 hm2 in the study area decreased year by year. Among them, the area of the contiguously planted rice with a scale above 6.67×103 hm2 decreased by 7.38% in average and the area of the contiguously planted rice with a scale between 3.34×103 hm2 and 6.67×103 hm2 decreased by 2.40% in average, while the area of the contiguously planted rice with a scale between 0.67×103 hm2 and 3.33×103 hm2 decreased by 0.76% in average. Secondly, the area of the contiguously planted rice with a scale above 6.67×103 hm2 in Hongze County, the junction of Donghai County, Guanyun County and Lianyungang urban areas as well as Donghai County continued to remain stable. Area of the contiguously planted rice with a scale above 6.67×103 hm2 in the junction of Chuzhou District of Huaian City, Binhai County, Sheyang County and Funing County as well as Yandu District of Yancheng City varied greatly from large to small or from presence to absence. Thirdly, as the scale of rice contiguous planting areas shrinked, rice planted in the contiguous areas became monolithic gradually and the spatial distribution compactness of paddy fields increased. The method proposed in this research of using the spacing between fields to define whether the fields are contiguous or not can effectively solve the quantitative problem in regional contiguous planting of crops on a large scale.
