利用Arc GIS强大的空间分析及建模功能优势,运用栅格计算、空间分析等方法构建国家级公益林保护等级智能划分的图解模型,对贵州省都匀市国家级公益林保护等级进行划分。研究结果表明该方法能有效提高划分的精度和效率,避免了传统方法工作量大、人为操作误差等弊端,可为贵州省国家级公益林区划界定工作提供借鉴价值。 Utilizing ArcGIS’s strong spatial analysis and modeling advantages, this paper constructs a graphical model of state-level protection level intelligent division of public welfare forests by using grid computing and spatial analysis, and divides the level of protection of national-level public welfare forests in Duyun City, Guizhou Province. The results show that this method can effectively improve the accuracy and efficiency of the classification, avoid the disadvantages of traditional methods such as heavy workload and human error, and provide reference value for the demarcation of state-level public welfare forest in Guizhou Province.
