尝试了用表土地球化学转换函数恢复渭南剖面最近１３ 万ａ 来的古温度、古降水。结果显示：（１）全新世适宜期及末次间冰期时，降水量显著增加，渭南地区的年降水量可大于７００ ｍ ｍ ；（２）末次冰期时降水量明显低于全新世适宜期及末次间冰期，但是这一时期有一些次一级的变化，特别是与深海Ｏ 同位素阶段４ 对应的时期，不仅降水量显著降低，而且还有更次一级的变化；（３） 全新世适宜期时，渭南地区的年平均温度在１２～１４ ℃左右，末次冰期时年平均温度在８．５～１１．５ ℃左右，而末次间冰期的古温度在１２～１５ ℃之间。
Attempt to recover the paleo-temperature and paleo-precipitation of the last 130,000 years in the Weinan section with surface geochemical transformation function. The results show that: (1) During the Holocene interglacial period and the last interglacial period, the precipitation increased significantly, and the annual precipitation in Weinan area could be more than 700 m m. (2) The precipitation in the last glacial period was obviously lower than the Holocene suitable period and the last Interglacial period, but there are some sub-level changes in this period, especially during the period corresponding to the O isotope stage 4 in the deep-sea, not only with a significant decrease in precipitation, but also in more sub-stage changes; (3) , The annual average temperature in Weinan is about 12-14 ℃, the average temperature in the last glacial period is 8.5-1.5 ℃, while the palaeoclimate in the last interglacial period is 12-15 ℃.
