Yes, in your user_nl_clm. Just specify the location and name of your file.

double PCT_NAT_PFT(natpft, lsmlat, lsmlon) ;
PCT_NAT_PFT:long_name = "percent plant functional type on the natural veg landunit (% of landunit)" ;
PCT_NAT_PFT:units = "unitless" ;

See this table in the CLM User's Guide for the list of pfts:

2.2. Surface Characterization, Vertical Discretization, and Model Input Requirements — ctsm CTSM master documentation

I want to know what's difference between lsmlon and longtitude？ Is there any function mapping between them? What do I do if I want to get the common latitude/longitude grid?

Here is the example using the plot for PCT_NATVEG variable in the surfdata_0.9x1.25_hist_16pfts_Irrig_CMIP6_simyr1850_c190214 file.
