| 摘 要： | 为了探究四川省作物种植结构与气候变化的协调关系,本研究基于四川省气候数据与农作物播种面积数据,分析了2000—2018年四川气候变化、农作物种植结构变化以及它们之间的协调关系。结果发现：四川省2000—2018年间降水量、≥10℃积温均呈显著上升趋势,降水量气候倾向率为53.5 mm/10 a,≥10℃积温气候倾向率为123.7℃/10 a;作物播种面积明显增加的有玉米、油料作物、豆类、果园,薯类播种面积保持相对稳定状态,作物播种面积明显下降的有水稻、小麦和其他作物;各主要农作物种植结构占比变化明显。四川省农作物种植占比前三种为水稻、玉米和薯类,多年平均占比分别为21%、17%和13%,且水稻在所有种类中占比较稳定;小麦种植占比正在逐年降低。四川省2000—2018年农作物种植结构变化与气候变化整体相互适应,耦合度与耦合协调度均较高。

| Abstract: | To explore the coordinated relationship between crop planting structure and climate change in Sichuan Province, based on the climate data and crop planting area data of the province, this study analyzed the climate change, crop planting structure change and their coordination relationship from 2000 to 2018. The results showed that: from 2000 to 2018, the precipitation and accumulated temperature ≥10℃ in Sichuan showed a significantly upward trend, the climate tendency rate of precipitation was 53.5 mm/10 a, and the climate tendency rate of accumulated temperature≥10℃ was 123.7℃/10 a; the planting area of maize, oil crops, legumes and fruits increased significantly, the planting area of potato remained relatively stable, and the planting area of rice, wheat and other crops decreased significantly, and the proportion of planting structure of main crops changed significantly. The top three crops in Sichuan Province were rice, maize and potato, with an average proportion of 21%, 17% and 13%, respectively, and the proportion of rice was relatively stable among all kinds of crops; the proportion of wheat was decreasing year by year. The crop planting structure change and climate change in Sichuan Province from 2000 to 2018 were compatible with each other, and the coupling degree and coupling coordination degree were high. |
