4种绿化造林面积验收方法的比较研究

为有效解决大规模绿化造林面积验收精度差、效率低，成果信息化、可视化程度低的问题，以张家口地区为例，对比分析4种常用绿化造林面积验收方法。结果表明，奥维互动地图软件勾绘验收和利用无人机技术验收是适用性较强的两种方法。当地势平缓，地标地物明显时，奥维互动地图软件勾绘验收方法灵活、准确、易操作；当地形复杂，造林地块多位于山区、沟壑地带时，无人机技术验收精度高、外业劳动强度低，成果信息化、可视化程度高。

Comparative Analysis of Four Acceptance Methods for Afforestation Area

In order to effectively solve the problems in the large-scale afforestation area acceptance, such as poor accuracy, low efficiency, and low degree of information and visualization, this paper comparatively analyzed four commonly used acceptance methods for afforestation area based on the case of Zhangjiakou region. The results showed that the Ovital map and unmanned aerial vehicle were the suitable methods with strong applicability. When the local terrain is gentle and the landmarks are obvious, the acceptance method of the Ovital map is flexible, accurate and easy to operate. When the local terrain is complex and the afforestation plots are mostly located in mountainous areas and ravines, the acceptance method of unmanned aerial vehicle is a better choice with a high acceptance accuracy, low labor intensity, and the acceptance results are informationized and visualized with high degree.
