| 随着气候变化及种植结构调整，农业水土资源配置状况发生改变，研究农业水土资源匹配特征对农业可持续发展具有重要意义。基于作物生产水足迹视角，采用广义农业水土资源匹配系数的计算方法，对 1985—2018年辽宁省春玉米生育期的水土资源匹配特征进行分析。结果表明：1985—2018 年间辽宁省春玉米农业水土资源匹配系数变化波动明显，总体以 14 m3/（hm2·a）增长，多年平均农业水土资源匹配系数值为 5733 m3/hm2。同时，1985—2018 年间辽宁省春玉米农业水土资源匹配状况呈现向好趋势，东部农业水土资源匹配良好的地区增多，西北部农业水土资源匹配较差的范围缩小。未来辽宁省玉米种植结构调整，应立足各地区农业水土资源匹配特征，构建水土资源空间均衡的农业生产体系。 |

| With the warming of climate and the adjustment of planting structure, the allocation of agricultural soil and water resources has also changed, and it is of great significance to study the matching characteristics of agricultural soil and water resources for the sustainable development of agriculture. Based on the perspective of crop production water footprint, the characteristics of soil and water resources matching in spring maize growing period of Liaoning Province from 1985 to 2018 were analyzed by using the calculation method of generalized agricultural soil and water resources matching coefficient. The results show that:the variation of soil and water resources matching coefficient of spring maize in Liaoning Province from 1985 to 2018 fluctuats obviously, with an increase of 14.18 m3/hm2·a-1, and the average annual agricultural soil and water resources matching coefficient is 5733.08 m3/hm2. From the change of spatial matching pattern, the matching situation of spring maize agricultural soil and water resources in Liaoning Province shows a better trend between 1985 and 2018, and the areas with good matching of agricultural soil and water resources in the eastern region increase, and the range of poor matching of agricultural soil and water resources in the northwest decreases. In the future, the adjustment of maize planting structure in Liaoning Province should be based on the matching characteristics ofagricultural soil and water resources in various regions, and construct a balanced agricultural production system of soil and water resources in space. |
