Quantitative analysis of 3579 trees recorded in the Classic Maya city of Cobá, Quintana Roo, Mexico, indicates a strong relation between the location and quantity of certain trees producing fruit, fiber, bark, and resin, high-status vaulted architecture, and their distance from the center of the site out toward the fringes. The relationships suggest agreement between the residence pattern of Cobá and Diego de Landa's 16th-century class-oriented description of Maya towns during preconquest times.
对墨西哥金塔纳罗奥州科巴古城 3579 棵树木的定量分析表明，某些生产水果、纤维、树皮和树脂的树木的位置和数量、具有高地位的拱形建筑，以及它们与遗址中心的距离与边缘之间存在密切关系。这些关系表明，科巴的居住模式与迭戈·德兰达（Diego de Landa）在征服前时期对玛雅城镇的 16 世纪面向阶层的描述相符。
