摘要: 【目的】 探究东北三省(以下简称东三省)主要粮食作物种植结构的时空演变。【方法】 采用决策树法,基于MOD13Q1数据,结合农作物物候数据和东三省土地利用数据,运用景观指数对东三省主要粮食作物——玉米、水稻和大豆种植结构的时空演变进行分析。【结果】 2000—2015年东三省玉米和大豆的平均斑块面积持续增长,斑块密度持续下降,斑块聚合度在整体上呈增加趋势。2000—2010年东三省水稻平均斑块面积持续增长,斑块密度持续减少;2010—2015年水稻平均斑块面积减少,斑块密度增加;2000—2015年水稻斑块聚合度处于稳定状态。【结论】 从种植结构来看,2000年大豆是东三省最主要的粮食作物,2005—2015年玉米是东三省最主要的粮食作物;从种植格局来看,东三省玉米和大豆的种植一直比较集中,水稻种植在2010—2015年出现轻微的破碎化现象,但整体上相对集中。

Abstract: 【Objective】To explore the spatio-temporal evolution of the main food crops planting structure in the three northeastern provinces.【Methods】Using the decision tree method,based on MOD13Q1 data,combined with crops phenology data and land use data in the three northeastern provinces,the landscape index was used to analyze the spatio-temporal evolution of the planting structure of the main food crops in the three northeastern provinces—maize,rice and soybean.【Results】From 2000 to 2015,the average patch area of maize and soybean in the three northeastern provinces continued to increase,the patch density continued to decrease,and the patch aggregation degree increased on the whole. From 2000 to 2010,the average patch area of rice continued to increase and the patch density continued to decrease. From 2010 to 2015,the average patch area of rice decreased and the patch density increased. From 2000 to 2015,the patch aggregation degree of rice has been in a stable state.【Conclusion】From the perspective of planting structure,soybean was the most important crop in the three northeastern provinces in 2000,and maize was the most important crop in the three northeastern provinces from 2005 to 2015. From the perspective of planting pattern,the planting of maize and soybean in the three northeastern provinces has been relatively concentrated,and the rice planting showed a slight fragmentation phenomenon from 2010 to 2015,but it was relatively concentrated overall.
