In the recent years, the agroclimatic investigations have been made at various temporal and spatial scales in mountainy and hilly regions, and so have the adaptability tests on the plant ecoclimate. A large quantity of reliable and representitive data have been obtained.Through the synthetic studies on "belt" , "layer" , "topography"and "ecological-type" in mountainy and hilly regions have been taken, climate with agriculture, zone with non-zone to show the similarities and differences of agroclimatic resources at various layers and with different topography types in mountainy and hilly regions. A general review is given here on the above studies.
