| 摘要: |
| 定量评估水土资源匹配程度对于保障区域水土资源可持续开发利用和粮食生产安全具有重要意义。本文小三江平原为研究对象，构建了水土资源匹配测算模型，分析了小三江平原水土资源匹配系数时空变化情况。结果表明：2015年小三江平原水土资源匹配系数仅为0.542，低于黑龙江省平均水平；从空间变化角度来看，小三江平原水土资源匹配呈现为“北高南低、西高东低，边缘高腹地低”的格局；从时间变化角度来看，过去的30多年间，小三江平原水土资源匹配系数则呈现逐年递减趋势。因此，小三江平原应通过强化过境水资源利用、加强水利工程设施建设、提升节水灌溉技术和合理分配种植结构，提高区域水土资源匹配系数，保障区域水土资源可持续开发利用和粮食生产。 |

| Abstract: |
| Quantitative evaluations of the spatial matching of water and land resources can contribute to the rational utilisation of water and land resources and ensure food security. This paper took the small Sanjiang plain as the research object, and A corresponding framework for the quantitative evaluation of the water and land resources spatial matching is proposed. The matching coefficient of water and land resources is 0.542 in the Small Sanjiang plain in 2010, lower than the average level of Heilongjiang Province. The matching coefficient of was Southeast low northwest high in the small Sanjiang plain. Ovre 30 years, the matching coefficient of water and soil resources in the Sanjiang Plain showed a decreased trend. These results show that the spatial matching of water and land resources should be further optimised by introducing inter-basin water transfer projects, developing water conservation agricultural practices, revising the planting structure and further optimising water and land resource allocation. |
