中文摘要：

系统记述了广西崇左三合大洞早更新世堆积中出土的与巨猿伴生的小猪（Sus xiaozhu）和裴氏猪（Speii）。三合大洞是小猪在我国境内至少为第12个产地，也是目前最靠南的产地。小猪在三合大洞的发现进一步证实了小猪的繁盛时期是早更新世，繁盛地区在广西。三合大洞是裴氏猪在我国境内至少第9个产地，也是裴氏猪在我国境内目前最靠南的记录。裴氏猪在三合大洞的发现同样证实了裴氏猪的繁盛时期是早更新世，繁盛地区也在广西。虽然小猪的时代分布从早更新世早期起并可能延续到晚更新世早期，裴氏猪的时代分布从早更新世早期到中更新世早期，但是迄今发现的小猪与裴氏猪同时产出的层位均为早更新世地层，而三合大洞是迄今我国境内第6个小猪和裴氏猪伴生的早更新世地点。小猪和裴氏猪也经常出现在巨猿产地，三合大洞是迄今它们共生的第5个地点。小猪和裴氏猪在三合大洞的出现指示三合地区在早更新世具有近水的森林和灌丛环境。

英文摘要：

Two suids identified as Sus xiaozhu and S. peii associated with Gigantopithecus unearthed from Sanhe Cave are systematically described. Sanhe Cave is at least the 12th site yielding S. xiaozhu and at least the 9th site yielding S. peii, both finds recognized as the southernmost location in China so far. This evidence confirms the thriving period of both S. xiaozhu and S. peii in the Early Pleistocene and Guangxi as their favorable habitat. Although S. xiaozhu chronologically ranges from the early stage of the Early Pleistocene to the early stage of the Late Pleistocene and S. peii chronologically ranges from the early stage of the Early Pleistocene to the early stage of the Middle Pleistocene, the co-occurrence of S. xiaozhu and S. peii happens always in the Lower Pleistocene. Sanhe Cave is the 6th Early Pleistocene site yielding both types of suids, which are often found with Gigantopithecus; Sanhe Cave is the 5th site with such an association. The presence of these two suids indicates that the Early Pleistocene environment around the cave was forested with scrub and swamps nearby.
