| 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. |
