%X The vertical division of agrotopoclimate is carried out by the way of principal component analysis in the warm gorge sectors in the southwest of Hubei Province. According to the calculation, three layers are divided in the warm gorge sectors: hot layer (<300 m), warm layer (300~600 m) and mild layer (600~800 m). Such division provides a theoretical basis for setting up the rational allocation of three-dimensional agriculture. On the basis of the vertical division , decision on agricultural development strategy is carried out by means of analytical hierarchy process in the warm gorge sectors. It is necessary even in the same layer to select agricultural and forest crops that are suitable to the agroclimatic characteristics of microclimate environments, so that we can bring the agroclimatic superiority and potentiality into full play, develop agriculture and diversified economy, and protect the ecological balance. The conclusion will be good for the further use of agroclimatic resources and give an essential help for working out strategic objectives of agricultural development in the area.
