您使用的是哪个版本的代码？
CLM4.5 系列
您是否对源代码树中的文件进行了任何更改？
no
描述导致问题发生所采取的每个步骤：
I utilized the I850CLMCN component of CLM to simulate the carbon cycle in permafrost peatlands. My SSP5-8.5 simulation results unexpectedly showed significant carbon sink capacity by 2100, which contradicts established knowledge. I would like to inquire whether the permafrost thaw-freeze module in CLM4.5 can be modified to better represent freeze-thaw dynamics in northern permafrost peatlands.
如果这是新计算机的端口：请附上您为计算机端口添加或更改的任何文件（例如，config_compilers.xml、config_machines.xml 和 config_batch.xml），并告诉我们您在这台机器上使用的编译器版本。
请附上任何显示错误消息或其他有用信息的日志文件。
