The goal of archaeology can be traditionally defined as ``the systematic study of antiquities as a means of reconstructing the past`` (Grahame Clark) and as ``the method of finding out about the past of the human race in its material aspect and the study of the product of this past`` (Kathleen Kenyon) forming culture-historical point of view whose thoretical background lies in the chronological order and the specific description of culture events. But the recent trend of archaeological study has been changed since Lewis Binford had proposed so-called ``New Archaeology`` in 1960s whose theoretical background lies in the revelation and explanation of cultural process, and the general systems theory with the help of logico-deductive reasoning and computer-based simulation. As Gordon Willey mentioned earlier, ``American archaeology is anthropology or it is nothing`` which means that American archaeology is one kind of social science like anthropology. The reconstruction of the human past can be achieved not only from the establishment of chronological order and specific description of cultural events, but also from the explanation of cultural process and the fossilized behavior patterns of the human race shown as a result of human adaptation to physical environment and biota forming large ecosystem. Either do we apply ``direct historical approach``, ``ethnographic analogy`` or ``microenvironment approach`` or any kind of new method to the reconstruction of the human past, the real goal of archaeology should be formed from the synthesizing, cumparision and interpretation of various aspects of culture traits. Recently we use any kind of method for archaeological data regardless of new or old Schools.
