POLLEN ANALYSIS AT SITE 3324, A BURIED FISHPOND AND FIELD SYSTEM, WEST LOCH, OAHU

Pollen samples were collected from five locations in site 3324, a buried
pondfield system at West Loch. Backhoe Trench 4-41, as well as Cores 1 and 2
were collected from Area 4, which included buried fishponds. Backhoe Trench 4-41
was opened immediately outside Buried Fishpond 3322. Cores 1 and 2 were
collected inside the Buried Fishpond 3322 location. Local tradition has it that
the area of Fishpond 3322 functioned as a taro field, then rice field in historic
tines. Cores 3 and 4 were collected in Area 2, which included upland sediments.
Core 3 was retrieved from an area referred to as the lower Field System, while Core
4 was collected from the Upper Field System. Pollen analysis was undertaken to
provide a record of past vegetation in these locations, and in an effort to
identify any agricultural activities.

本研究的孢粉样本采自西洛赫（West Loch）埋藏塘田系统3324号遗址的5处采样点位。其中，挖掘机探沟4-41与岩芯1、2均采集自包含埋藏鱼塘的4号区域：挖掘机探沟4-41开挖于埋藏鱼塘3322的紧邻外侧，岩芯1、2则采集自该埋藏鱼塘3322的内部区域。据当地口述传统，3322号鱼塘区域在历史时期曾先后作为芋艿田与稻田使用。岩芯3与4采自包含高地沉积物的2号区域，其中岩芯3取自被称为“下部田块系统”的区域，岩芯4取自“上部田块系统”。本次研究开展孢粉分析（pollen analysis），以记录上述点位的古植被演化记录，并识别区域内曾存在的农业活动痕迹。
