| 摘 要： | 以宜宾市长宁县为研究区，基于多源数据，在栅格尺度上量化了土地利用功能。利用景观叠加分析及相关性分析等方法，明确了土地多功能性的空间分异特征，并揭示了土地功能与地形要素之间的地理空间过渡性关联。结果表明：① 山区过渡性地理空间土地生产、生态和生活功能具有多组合性，空间异质性较强。② 长宁县土地多功能性在空间上由北部平原向南部山区过渡递增，多重和双重功能主导的土地主要分布在中部槽谷和南部山区，占土地总面积的50%以上。③ 地形因子对土地多功能景观的形成发挥较大的作用，海拔650 m、地形起伏度200 m、坡度15°是土地利用多功能性的临界值，超过此临界值土地多功能性趋于减少，但生态功能占居主导。 |

| Abstract: | The ecological, production and living functions of the Transitional geo-space in the mountainous area are highly complex, and the pattern and structure of the three directly affect the multi-functionality and rationality of the land use. There is a multi-objective trade-off relationship between ecological protection and economic and social development in this area, and it is a key area for land space development and pattern optimization. The study takes Changning County, Yibin City as the research area, and quantifies land use functions on a grid scale based on multi-source data. Through landscape superposition analysis and correlation analysis methods, the spatial differentiation characteristics of land multi-functionality are clarified, and the geographic spatial transitional relationship between land functions and terrain factors is revealed. The results show that: 1) The production, ecological and living functions of the transitional geo-space in the mountainous area have multiple combinations and strong spatial heterogeneity. 2) The multi-functionality of the land presents an increasing trend in the transition from the northern plain to the mountainous area in the south. The land dominated by multiple and dual functions is mainly distributed in the central trough and the southern mountainous area, accounting for more than 50% of the total land area. 3) Terrain factors play a major role in the formation of multi-functional landscapes. The critical value of land use multi-function is 650 m above sea level, 200 m topographic relief and 15° slope. Beyond this critical value, land multi-function will tend to decrease, but ecological function will dominate. |
