摘  要:研究少数民族山区的土地利用对其实现国土空间格局优化和脱贫致富具有重要的现实意义。该文以云南省南涧彝族自治县80个行政村为评价单元,基于"三生"功能理论构建评价指标体系,运用土地利用多功能测算模型、空间自相关和地理探测器等方法,系统分析2008-2017年该区域土地利用多功能时空分异特征和影响因素及其动态变化。结果表明:1)2008-2017年南涧彝族自治县土地利用多功能水平提升较快,生态功能水平最高,生产功能和生活功能变化幅度最大;2)2008-2017年南涧彝族自治县土地利用多功能空间分异明显,二级功能空间分布呈现不同的空间形态特征,土地利用多功能空间分布呈现"北高南低、一主两副"的格局;3)2008-2017年南涧彝族自治县土地利用多功能空间分异的影响因素变化较大,主导因素从自然资源禀赋转向社会经济和区域政策因素,其变化主要以增强型和稳定型为主,且存在5个增强型因素,4个稳定型因素和3个减弱型因素。The study of land use in ethnic mountainous regions is of great practical significance to optimization of the spatial pattern of land and alleviation of poverty in the regions in question. In this paper, with 80 administrative villages in Nanjian Yi autonomous county in Yunnan Province as the evaluation units, an evaluation index system based on the "production-living-ecological" functions theory was established;on top of that, the spatio-temporal diversity and influencing factors of the multifunctionality of land use in the area during the period from 2008 to 2017, as well as their dynamic change, were systematically analyzed using the measurement model of multi-functionality of land use, spatial autocorrelation, geo-detector and other tools. The results indicated that: 1)from 2008 to 2017, the multifunctionality of land use in Nanjian Yi autonomous county improved fast, the level of multifunctionality in 2017 being almost 50% higher than that of 2008, with 67 out of 80 administrative villages across the county at intermediate level or above. In the meantime, the development of various functional levels was uneven. The ecological function of land use was the highest, while the production function and living function grew faster. Among the secondary functions of land use, the ecological conservation function and ecological purification function were higher, followed by the agricultural production function and social security function, and the residential support function and economic development function were relatively lower, but the economic development function changed the most.2)from 2008 to 2017, the multifunctionality of land use in Nanjian Yi autonomous county was found with obvious diversity in spatial distribution, showing a "higher in the north and lower in the south" spatial pattern of "one center and two sub-centers". The spatial distribution of production functions therein was in clusters, and was expanding with the county town and the flat basin area of Gonglang town as centers;living functions, on
