Following the completion of the 5700m2 RPC carpet-like AS array at YangBaJing this year, a further plan based on the ARGO Carpet is raised. It characterizes with its high altitude site, its full-coverage detector array and the multi-parameter measurements. Apart from studies on TeV and sub-TeV energy range, UHE Gamma-ray sources and the Knee Physics will become its characteristic subjects. In the first phase of the plan, the Yangbajing Super Complex Array (YSCA) will include a 104m2 RPC Carpet, five indoor μ-detectors (∼170 m2each), four big outdoor μ-detectors (∼432 m2 each) and a traditional field scintillation detector array surrounding the Carpet. Monte-Carlo study shows that, with such an array in YBJ (4300m a.s.l.), γ-ray induced air showers can be separated from proton induced air showers clearly using only the observed electron and μ data event by event. To assist the classification of UHE air showers induced by different primary nuclei groups without severe interference by Composition/Model Entanglement, a second phase plan having a Central Burst Detector Array (CBDA) and some pulse shape detectors is schemed.
