摘　　要：研究选取高程、坡度、坡向、植被覆盖度、道路缓冲区、土地利用类型6个影响因子,采用Arc GIS空间分析技术对石佛沟国家森林公园单因子进行综合分析,根据现状有针对性地提出对策与建议。结果表明,石佛沟国家森林公园极度敏感区、高度敏感区、中度敏感区、轻度敏感区、极低敏感区分别占总面积的9.19%、24.89%、20.28%、27.19%、18.45%。极度敏感区和高度敏感区主要分布于公园的西部、东部和南部,其海拔高、坡度大、土地利用多为林地、植被覆盖度较低;中度敏感区在公园零散分布,其海拔较高,土地利用以灌木林地和草地为主;轻度敏感区和极低敏感区集中分布在有耕地和乡村建设区等开发建设程度较高的区域。研究区主要集中在轻度敏感到高度敏感范围。The study selected six influencing factors including elevation,slope,aspect,vegetation coverage,road buffer zone and land use type were selected.The single factor of Shifogou National Forest Park was comprehensively analyzed by ArcGis spatial analysis technology,and the countermeasures and suggestions were put forward according to the current situation.The results showed that the extremely sensitive area,highly sensitive area,moderately sensitive area,mildly sensitive area and extremely low sensitive area of Shifogou National Forest Park accounted for 9.19%,24.89%,20.28%,27.19%and 18.45%of the total area,respectively.The extremely sensitive areas and highly sensitive areas are mainly distributed in the west,east and south of the park,with high altitude,large slope,mostly woodland and low vegetation coverage.The moderately sensitive areas are scattered in the park,with high altitude,and the land use is dominated by shrub land and grassland.Mild sensitive areas and very low sensitive areas are concentrated in areas with high development and construction,such as cultivated land and rural construction areas.The study area is mainly concentrated in the mildly sensitive to highly sensitive range.
