| Abstract: | Under the background of cultivated land resource shortage and an increasing contradiction between human and land in east China, it is urgent to increase cultivated land to ensure a ‘balance of occupation and compensation’. Coastal saline-alkali land, as a potential land reserve resource, has strategic and practical significance by its rational development and utilization to alleviate the pressure of land resource shortage, improve agricultural water resource utilization efficiency and ecosystem stability. This paper introduced the current situation and main characteristics of coastal saline-alkali land resources, and summarized the recent research progress and existing problems of coastal saline-alkali land improvement and utilization from the physical, chemical, hydraulic engineering and biological aspects, and put forward the research prospect of coastal saline-alkali land in the future from biophysical process, obstacle reduction, soil fertility improvement and nutrient expansion, development and application of new materials, soil carbon sequestration, and comprehensive management and remediation, aiming to provide new ideas, new technologies and theoretical support for coastal saline-alkali soil improvement under the background of ecological civilization in the new era. |
