total dissolved solid

The research on the karst collapse distribution and the hydrogeochemical environmental characteristics of Guilin city shows that SIc value is closely related to the collapse distribution, secondly pco2, but the total dissolved solid, the hardness and SID value are weekly related to it.

对桂林市岩溶塌陷分布及其水文地球化学环境特征研究表明，塌陷分布与SIc值的关系较密切，与Pco2次之，而与矿化度、硬度、SID值的关系不明显。
