石河子地区的热量资源与绿洲农业Ⅱ、准噶尔盆地沙漠沉积冷空气对石河子绿洲农业影响的研究

新疆内流型绿洲的最大特点是绿洲分布在山前至沙漠的倾斜平原上,形成沙漠与绿洲不同部位的高度差。冬季处于地势低洼的沙漠沉积冷空气最多,绿洲则随着高度上升而冷空气逐渐减少,导致不同部位的温度差异,影响作物布局及有关农业技术。石河子地区夏季沙漠的增温效应直接影响绿洲不同部位的气温,形成距离沙漠越远,温度越低,呈负相关关系(r=-0.8813*);冬季沙漠与绿洲由于沉积冷空气多少的差异,也形成距离与温度的弱正相关关系(r=0.8489);在春、秋季沙漠与绿洲间的温度则无相关关系(r=-0.4218及0.5524)。以上共同构成石河子绿洲农业的热量特征。

Oasis Agriculture and Calories Resources in Shihezi Region Ⅱ、Studying the Affection of Skin to Accumulate the Cold Air of Deserton Oasis Agriculture

The characteristics of the oasis is the distribution on the mountains left for the desert' s inclination plain in Xinjiang,forming high degree between desert and oasis, the winter locates the low-lying and damp desert of geography to sink to accumulate the cold air at most, the oasis is then to rise with the high degree but the cold air gradually reduces, causes the difference of the different part of temperature, influences crop patterns and agriculture technique concerned.. The improving temperature effect of desertly directly influences air temperature in different parts of oasis in summer, the lower temperature is, the far distance is, and both report the negative related relation ( r = - 0.8289) , due to the difference sinking to accumulate the cold air of desert and oasis in winter, and form distance and temperature of related relation ( r = 0.8489), there is nothing to do with the related relation ( r = -0.4218,r=0.5524) the temperature between desert and oasis in spring and autumn,commonly constituting the oasis agriculture.
