摘要
本文分析了ArcGIS在湖北省恩施市森林资源调查规划设计中的应用成效。于湖北省恩施市某林场开展调查研究,借助ArcGIS的整理编辑功能、专题制图功能、设计小班调查功能以及逻辑检查功能和统计分析与报表生成等功能,实现对林场不同样地(Z1、Z2、Z3,Z4)的调查,以分析ArcGIS在森林资源调查规划设计中的具体作用。结果表明:ArcGIS可对不同处理的森林分布、植被类型、地貌地形以及林区郁闭度进行准确分析,其中Z1处理属于低、中海拔区,林区郁闭度和植被覆盖率分别为0.67和92.35%;Z2处理属于中海拔区,林区郁闭度和植被覆盖率分别为0.68和92.69%;Z3处理属于低海拔区,林区郁闭度和植被覆盖率分别为0.64%和85.25%;Z4处理属于高海拔区,林区郁闭度和植被覆盖率分别为0.60和80.36%;此外ArcGIS可实现对幼龄林、中龄林、近熟林、成熟林和过熟林不同林龄的动态监测以及对森林资源生态环境、水文地质条件和林木长势进行评估。指出了ArcGIS森林资源调查规划设计中可通过对数据的整合,生成直观的三维图像,有助于清晰地展示林业分区情况,实现林地资源的高效、精准管理,还可辅助调查人员进行科学决策。
This study analyzes the application effect of ArcGIS in forest resources survey planning and design in Enshi City,Hubei Province.A forest farm in Enshi City,Hubei Province conducted an investigative study utilizing various functionalities of ArcGIS,including data compilation and editing,thematic mapping,design of subcompartment surveys,logical checks,statistical analysis,and report generation.The study aimed to survey different sample plots(Z1,Z2,Z3,Z4)within the forest farm to analyze the specific role of ArcGIS in the planning and design of forest resource surveys.The results show that ArcGIS can accurately analyze forest distribution,vegetation types,geomorphology and forest canopy in different treatments.Z1 treatment belongs to low and medium altitude areas,and forest canopy and vegetation coverage rate are 0.67 and 92.35%,respectively;Z2 treatment belongs to the middle altitude area,and the forest canopy and vegetation coverage rate are 0.68 and 92.69%,respectively;Z3 treatment belongs to low altitude area,and forest canopy and vegetation coverage rate are 0.64%and 85.25%,respectively;Z4 treatment belongs to high altitude area,and forest canopy and vegetation coverage rate are 0.60 and 80.36%,respectively.In addition,ArcGIS can realize the dynamic monitoring of young forest,middle-aged forest,near mature forest,mature forest and over-mature forest at different ages,as well as the assessment of forest resource ecological environment,hydrogeological conditions and tree growth.In the planning and design of ArcGIS forest resources survey,data can be integrated to generate intuitive three-dimensional images,which is helpful to clearly display the forestry zoning situation,achieve efficient and accurate management of forest resources,and assist investigators to make scientific decisions.
