摘要
对西南山区盘州市的城镇建设用地进行适应性评价,为西南山区及盘州市的城镇规划、土地开发、城镇开发边界划定等提供理论价值参考。根据盘州市自然环境及其实际情况,选取高程、地形坡度、地形坡向、地形起伏度4项因子,基于GIS空间分析法进行了综合评价。结果表明:城镇建设用地适宜性评价等级以低和较低等级为主,其中低等级的区域面积占总区域的56.27%,较低等级的区域面积占总区域的20.88%。住宅类城镇建设用地适宜性评价等级也以低和较低等级为主,其中低等级的区域面积占总区域的73.96%,较低等级的区域面积占总区域的14.68%。评价结果揭示了盘州市城镇建设用地及住宅类城镇建设用地适宜性评价等级及其空间分布特征,其中适宜性的较高、高等级的城镇建设及住宅类城镇建设用地土地较少,而高等级均只占全区面积的1%左右,因此在利用该等级区域土地应需十分珍惜。
This paper evaluates the adaptability of urban construction land in the southwestern mountainous area of Panzhou City,which provides theoretical value reference for urban planning,land development,and boundary delineation of urban development in the southwestern mountainous area and Panzhou City.Based on its natural environment and the actual situation of Panzhou City,four factors including elevation,terrain slope,terrain aspect,and terrain undulation were selected for comprehensive evaluation using GIS spatial analysis method.The suitability evaluation level of urban construction land is mainly low and lower,with the area of low-level areas accounting for 56.27%of the total area,and the area of lower-level areas accounting for 20.88%of the total area.The suitability evaluation level of residential urban construction land is mainly based on low and lower levels,with low level areas accounting for 73.96%of the total area and lower-level areas accounting for 14.68%of the total area.The evaluation results reveal the suitability evaluation levels and spatial distribution characteristics of urban construction land and residential urban construction land in Panzhou City.Among them,there are relatively few lands with high suitability and high-grade urban construction and residential urban construction land,and high-grade land only accounts for about 1%of the entire area.Therefore,when using land in this grade area,it is necessary to cherish and utilize this type of land.
