Abstract: In this paper the climatic characteristics of western kangsliu are firstly described and then the possibility of the development of cotton cultivation from the vew-point of climate conditions is discussed. It is pointed out that in this region during the growing season the sunlight is rich, the rainfall is scare.e and the weather is steady. These conditions surpass those of the cotton area in. the region of Yangtze River and Haung-he. But there are also defects for cotton development is this legion. Tliey are: (1)the growing season is short,(2)the weather is more changeable in spring,(3) the temperatur rises rapidly in spring and decreases rapidly in autumn and(4)in certain places the temperature is too low for cotton.To overcome these defects certain suggestions are made. After a careful comparison of the climata of difierant places on a subdivision of regions for cotton dovelopment is suggestad.
