Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of forest gap measurement, and particularly relates to a device for estimating forest gap data. BACKGROUND

[0002] In forestry research and ecosystem analysis, accurate measurement and data estimation of forest gaps are of great significance. Forest gaps refer to the void areas formed by the death or falling of trees in forests, and their size, shape and distribution characteristics have a significant impact on the dynamic changes of forest ecosystems, species diversity, light and water distribution.

[0003] Traditionally, the estimation of forest gap data often relies on manual field measurement and simple estimation methods. However, this approach has many limitations and shortcomings.

[0004] On the one hand, when manually measuring with conventional measuring tools such as tape measure, ruler, etc., due to the complex terrain of forest gaps, irregular shapes and undulations, errors are likely to occur during the measurement process, making it difficult to accurately outline the boundaries of the forest gap, resulting in inaccurate estimation of the perimeter and area.

[0005] On the other hand, for larger or specially shaped forest gaps, traditional measuring tools are very inconvenient to operate, requiring a lot of time and manpower. Moreover, in complex forest environments, carrying and using these tools may be subject to many restrictions, increasing the difficulty of measurement work.

[0006] In addition, some measurement methods based on satellite remote sensing or aerial images can obtain large-area forest gap information, but due to resolution and image interpretation limitations, small or detailed forest gaps may not provide sufficiently accurate data, and such methods are often costly and complex in data processing.

[0007] Therefore, we propose a device for estimating forest gap data, which not only has a simple structure, is easy to carry, improves measurement accuracy, and is suitable for various complex shapes and sizes of forest gap terrain. CONTENT OF THE UTILITY MODEL
