| 摘要: |
| 在对本寨洞9个滴水点沉积玻片的晶体沉积质量监测后发现，现代洞穴沉积量主要受控于温度变化，统计的8个玻片沉积中，有6个滴水点的沉积速率与温度呈正相关关系。滴水速率对沉积速率影响较小，在统计的8个滴水点中，只有BZ9滴水点受滴水速率影响明显，具有正相关关系。其环境意义为石笋的生长速率主要受温度控制，呈正相关关系，可作为古温度代用指标。 |

| Abstract: |
| Investigation of 9 sedimentary slides in the Benzhai cave in Guizhou province, the capacity of cave deposit is controlled by the temperature variation. According to the statistics of 8 sedimentary slides, the rate of deposition of 6 drop points is positively related to the temperature. Drop rate has little effect on the rate of deposition, and among 8 drop points, drop rate affects BZ9 clearly. Therefore, the stalagmite growth rate is mainly controlled by temperature, it is positively related to temperature, so it can be used as paleotemperature substitute index. |
