摘要：

通过研究黄龙钙华滩流处的沉积速率和气候要素之间的关系，发现钙华沉积速率对气候重建的指示意义，为利用黄龙古钙华重建当地的古气候奠定了理论依据。通过现场采集水样和钙华样品，进行水化学分析，并进行沉积速率的监测，研究黄龙内生钙华的沉积速率在时间上的变化及其主要控制机理，找出影响钙华沉积的主要因素，发现在雨季沉积速率具有显著的降水量效应，即在雨季降水较多的时间钙华的沉积速率受地表水和雨后坡面流的稀释作用也降低，旱季钙华的沉积速率主要受水温的影响。钙华沉积速率的季节变化与气候（降雨、水温）有很好的线性关系：雨季时以降水量控制为主，旱季时以水温控制为主。

Abstract:

This paper discusses the indication of travertine deposition rate to climate through an investigation on Huanglongs travertine shoal, which provides a theoretical basis for reconstructing Huanglongs ancient climate by using its ancient travertine. Based on water and travertine samples and deposition rate, this paper studies the deposition rate changes over time and its mechanism. The major factors for travertine deposition rate is largely controlled by waterfall, also influenced by groundwater and slope. During dry season, it is controlled by water temperature. A linear relation is shown between seasonal changes of travertine deposition rate and climate (waterfall and water temperature) that waterfall prevails during rainy season and water temperature during dry season.

Key words: travertine, deposition rate, climate, Huanglong
