Studies investigating the differential decomposition of remains on different surfaces have been limited to qualitative data. This study statistically analyses the differences in rate and pattern of decomposition between concrete, gravel and grass surfaces. A total of 11 pigs (Sus scrofa domesticus) were used in the study: three for the concrete and gravel surfaces each, and 5 for the grass surface. Results showed that there was no difference in the overall rate of decomposition between surfaces (p > 0.05); however, there were significant differences in the pattern of decomposition. Mummification was observed on all subjects in the study and may have been the reason for the similarities in the decomposition rates between surfaces. The results of this study show that in the intertwined relationship between factors affecting decomposition surface type may be overshadowed by other environmental factors.
研究人员对不同表面遗体分解的差异进行了研究，但仅限于定性数据。本研究通过统计学分析了混凝土、碎石和草地表面分解速率和模式的差异。本研究共使用了 11 头猪（Sus scrofa domesticus）：每 3 头用于混凝土和碎石表面，5 头用于草地表面。结果表明，表面分解的整体速率没有差异（p>0.05）；然而，分解模式存在显著差异。所有研究对象都出现了木乃伊化现象，这可能是导致表面分解速率相似的原因。本研究结果表明，在影响分解的因素相互交织的关系中，表面类型可能会被其他环境因素所掩盖。
