The increasing rate of deforestation leads to increased critical land in forestry, which leads to national critical lands. One of the areas that are critical of the critical land is the Sub-Sub Amandit of Hulu Sungai Selatan Regency. Efforts to rehabilitate forests and critical land can be made with approaches to empirical equation modeling, spatial land modeling and land cover simulation. Formulation of forest and land rehabilitation (RHL) model in a watershed should consider the problem of land criticality (TKL) and socioeconomic aspects. Formulation of the model refers to data obtained through the process of observation and interview. The result of the research before the simulation was done TKL there were 5 classes, that is: Not Critical (TK) 20,51 Ha, Critical Potential (PK) 18.786,44 Ha, Rather Critical (AK) 20.947,31 Ha, Critical (K) 10.062,31 Ha and Very Critical (SK) 105.60 Ha. The value of TP 0.88, (TP <1), means that the carrying capacity of the land can still accommodate more farmers. DASE value 41.64, means support for RHL activities very strong. Extensive model of RHL efforts in Amandite Upper Sub Watershed 15.193.52 Ha and the middle Section 15,922.37 Ha. In addition, there was also a decrease in the TKL as a result of simulation of land cover on RHL model above, where there were 5 TKL classes changed into 3 TKL classes, that is TK 20,51 Ha, PK 30,624,51 Ha and AK 19.27781 Ha.
