贫困山区耕地利用转型的时空格局研究——以云南玉龙纳西族自治县为例

Research on Spatial and Temporal Patterns of Arable Land Use Transformation in Poor Mountainous Areas:A Case Study of Yulong Naxi Autonomous County in Yunnan

运用综合指数法、空间分析法等现代空间数据处理方法测算2009、2017年玉龙纳西族自治县下辖的16个乡镇的耕地利用转型指数、转型幅度、转型速度。结果显示:以县政府所在地为中心的县城核心区域耕地利用转型较显著;转型幅度小的乡镇空间分布格局较分散,转型幅度大的区域较集聚,分布于全县的东南、西北角;2009~2017年间全县耕地利用转型空间区域转型差异显著。

This paper uses the modern spatial data processing methods such as comprehensive index method and spatial analysis method to calculate the cultivated land utilization transformation index,transformation range and transformation speed of 16 towns under the jurisdiction of Yulong Naxi autonomous county in 2009 and 2017.The results show that the transformation of farmland use in the core area of the county centered on the county government is significant.The spatial distribution pattern of towns with small transformation range is scattered,and the regions with large transformation range are more concentrated,and they are distributed in the southeast and northwest corners of the county.The spatial regional transformation of farmland use in the county during 2009~2017 is significantly different.
