摘　　要：针对造林地平整工程的土方量测算过程中高程点布设和获取较困难,工作量较大且往往由于布设不均匀导致获取的高程数据精度不高的问题,基于ArcGIS 10.2软件、CASS 10.1软件和91卫图助手(V19.3.4)软件,提出了一种土方测算办法,即通过ArcGIS 10.2软件创建方格网并提取平整区DEM模型的高程数据,利用91卫图助手(V19.3.4)下载平整区的DEM模型,利用CASS 10.1软件测算平整土方。本研究选取东山赤山国有防护林场赤山工区一个造林地平整工程为研究对象,采用上述测算方法测算其总填方为58720.57 m^(3),总挖方为8263.06 m^(3)。结果表明,该方法不仅有效解决了高程点布设工作量较大和分布不均匀的问题,而且还满足了造林地平整中土方计算的要求,为造林地平整土方的合理调配提供了数据支持。Addressing the challenges of difficulty in laying out and acquiring elevation points,heavy workload,and often low precision of elevation data due to uneven distribution during the earthwork volume estimation process for land preparation projects in afforestation,a method for earthwork estimation is proposed based on ArcGIS 10.2 software,CASS 10.1 software,and 91 Satellite Map Assistant(V19.3.4)software.The method involves creating a grid using ArcGIS10.2 software and extracting elevation data from the DEM model of the leveling area.The DEM model of the leveling area is downloaded using 91 Satellite Map Assistant(V19.3.4),and the leveling earthwork is calculated using CASS10.1 software.In this study,a land preparation project for afforestation in the Chishan Work Area of Dongshan Chishan State-owned Protective Forest Farm was selected as the research object.Using the estimation method,the total fill volume was calculated to be 58,720.57 m?and the total excavation volume to be 8,263.06 m?.The results indicate that this method not only effectively resolves the issues of heavy workload and uneven distribution in elevation point layout but also meets the requirements for earthwork calculation in land preparation for afforestation,providing data support for the reasonable allocation of earthwork in land preparation for afforestation.
