在介绍我国现行采伐限额执行情况检查技术思路的基础上,分析其存在的不足,并提出具体的改进方法和建议:利用地理信息系统进行样地布设和判读、利用高分辨率影像判读有证伐区的采伐情况、对无证成片采伐改全面判读验证为抽样判读实测、加强对大面积无证大片采伐和重大毁林案件的监测力度等。该方法的应用可以充分挖掘高分辨率影像的优势和潜力,降低外业踏查工作量,增加成果数据的准确度,提高检查工作效率,为森林资源管理和监测工作提供参考和借鉴。
On the basis of introducing the technical idea of checking the implementation of the current cutting quota in our country, this paper analyzes the shortcomings of the existing cutting quotas and puts forward specific methods and suggestions for improvement: using the geographic information system to set up and interpret plots and interpreting the evidence-based cutting through high-resolution imaging Area of the logging situation, a comprehensive interpretation of the unlicensed piecemeal cutting verification verification for sampling interpretation, to strengthen large-scale undocumented large-scale logging and major deforestation monitoring efforts. The application of this method can fully exploit the advantages and potential of high-resolution images, reduce the workload of field inspection, increase the accuracy of the results data and improve the inspection efficiency, and provide reference and reference for forest resource management and monitoring.
