Abstract

Abstract: Taking Jinzhong City of Shanxi Province as an example, the layout optimization path under the difference of national land spatial utilization efficiency was explored. Firstly, based on the analysis of land spatial utilization system, the land spatial utilization efficiency of Jinzhong City was measured. Secondly, the scenario plan and index system of national land spatial development and protection with efficiency as the core were constructed, and multi-criteria decision analysis was introduced to identify the advantages of spatial development. Finally, the land spatial utilization of Jinzhong City was optimized using the method of space superposition, classification and merger. The results showed that the land utilization efficiency of Jinzhong City had obvious spatial imbalance, showing the distribution characteristic of high in the east and west, and low in the middle. The western and northwestern plain areas of Jinzhong City had more advantages in urban development and agricultural production, which were mainly determined as urban advantage areas and agricultural advantage areas under different scenarios, while the eastern mountainous areas had prominent ecological advantages and were mainly classified as ecological advantage areas. There were six types of optimized territorial space zoning in Jinzhong City, including the urban core development area, agricultural core production area, ecological core protection area, urban-rural integration development area, ecological and agricultural development area, ecological and economic development area, and the overall distribution was relatively concentrated. Among them, the ecological core protection area had the largest area, accounting for 37.27%. The future development of Jinzhong City should adjust the land utilization structure, improve the factor input mechanism, and realize the efficient use of land space to support high-quality development according to the land spatial optimization zoning characteristics that the northwest mainly developed towns and agriculture, and the southeast mainly developed ecology.

Key words: national land spatial utilization efficiency, national land spatial utilization layout, zone optimization, high-quality development, Jinzhong City
