国土空间视角下的高原山地民族聚落空间格局研究——以保山隆阳区为例

Research on the Spatial Pattern of Plateau Mountain Ethnic Settlement from the Perspective of National Land Space:Taking Longyang District of Baoshan City as a Case

基于国土空间整体系统性视角总结民族聚落空间特征,以期为高原山地民族聚落保护与发展提供依据。研究利用遥感数字图像数据,运用GIS空间分析法研究保山市隆阳区民族聚落水平空间格局,分析自然条件海拔影响下的垂直空间格局。结果表明:隆阳区民族聚落水平空间分布整体呈现“坝区低密度—山区高密度”特征,坝区多为中大型聚落低值集聚,山区多为中小型聚落高值集聚;在垂直梯度上民族聚落用地规模呈现菱形变化的特点,随着海拔的增加先增高后降低,且不同民族聚落垂直梯度分异明显。受自然及民族文化的影响,隆阳区形成了具有地域特色的高原山地民族聚落格局特征,但在高原山地复杂性、脆弱性、独特性条件下,民族聚落格局保护与发展受到限制。

The overall systemic perspective of the national land space can summarize the characteristics of ethnic settlement space and thus provide the basis for the protection and development of plateau mountain national settlements.Using remote sensing digital image data,in this work,GIS spatial analysis method is used to investigate the horizontal spatial pattern of ethnic settlements in Longyang district of Baoshan city,as well as the vertical spatial pattern under the influence of natural conditions.Our results show that the horizontal spatial distribution of ethnic settlements in Longyang district can be characterized by“low density in the dam area-high density in the mountainous area”.Most of the dam areas are low-value clusters of medium and large-scale settlements,and most of the mountainous areas are high-value clusters of small and medium-sized settlements.The size of the national settlement land shows the characteristics of rhomboid change.It increases first and then decreases with the increase of the altitude,and the vertical gradient of different ethnic groups is distinct.Affected by nature and national culture,Longyang district has displayed the pattern of plateau mountainous ethnic settlements with regional characteristics.However,under the constraints of plateau mountain complexity,vulnerability and uniqueness,protection and development of ethnic settlement patterns should be preserved.
