Agroclimatic Study of Mountainous Regions and Its Progress in China

In recent years, the agroclimatic investigations have been made at various temporal and spatial scales in moun-tainous and hilly regions, and so have the adaptability tests on the crop ecoclimate. A large quantity of reliable and representative data are obtained. Through the synthetic studies on “bell”, “layer”, “topography” and “ecological-type” in mountainy and hilly regions, climate with agriculture and zonality with non-zonality are closely combined 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 in this paper.
