被伐树木整体分离痕迹检验中特殊特征和固有特征的运用

被伐树木形成的整体分离痕迹有其独特性,反映出特有的规律。本文介绍了在盗伐林木案件中,运用整体分离痕迹检验原理、方法,检验被伐树木分离面、分离缘的形态,检验其凸凹断茬特征、虫眼特征、裂纹特征、空心特征等特殊特征以及节子特征、年轮特征、木射线特征、树皮纹理特征等固有特征。特别是在两对应的锯断面之间木质完全缺失情况下,综合运用上述特征有针对性地检验,解决了部分被伐树木整体分离痕迹检验中分离痕迹能否作为同一认定证据、分离体是否原为同一整体的问题。文中所述对被伐树木上的特殊特征和固有特征的研究和运用,拓宽了被伐树木整体分离痕迹检验中特征标记的范围,为丰富被伐树木整体分离痕迹的检验方法提供了参考。

Application of Sawn-apart Boles from Lumbered Trees into Their Special and Inherent Marking Features

Ordinarily,the integral marks occurred into the lumbered trees on their entire sawn-apart stubs/boles,having peculiar patterns.Therefore,evidence is able to provide with such marks when they are to test in the case of illegal logging.From the broken stubs/boles,there are usually special features found of,e.g.,the wormholes,cracks and hollow cavities together with the inherent ones like the knots,annual growth rings,radial lines and bark texture.All the above-mentioned marks will defi nitely contribute evidential assemblage if they are totally and comprehensively examined into their harboring patterns/shapes on the severed boles,helping determine whether the involving marks can be regarded as the identifi cation evidence and/or whether the separated stubs/boles are of same tree/provenance when the ligneous substance is devoid of the sawn-apart surfaces.Taken into a case investigation of woods pillage,the special and inherent marks were here introduced about their features from the cut stubbles,wormholes,hollow cavities,cracks,knots,annual growth rings,radial lines and bark texture,with the relevant testing methods and utilization being elucidated.The experience and knowledge described here would be valuable for the same or similar examinations and case investigation.
