沙漠增温效应特征及其对绿洲农业的影响

Characteristics of improving temperature effect of desert and its affection on the oases agriculture

研究表明沙漠增温效应强弱随距离沙漠远近而不同,且表现出一定的分区规律;绿洲距沙漠的远近与气温间存在一定线性关系。沙漠增温效应对绿洲气候有多方面作用,形成夏季富照高温、冬季冷空气沉积而寒冷,日夜温差大等典型大陆性气候特征,且显著影响绿洲特色高效农业的产生及特殊栽培管理技术体系的形成。

The studies show that the improving temperature effect of desert is different with the distance to the desert, which is a kind of regional pattern. There is a linear relation between the distance from oases to desert and air temperature. There are lots of functions of improving temperature effect of desert to the oases climate, i. e. being higher-temperature and full-illumination in summer, lower-temperature in winter, bigger temperature difference between day and night and so on, these profoundly affect oases characteristic and high-benefit agriculture and cultivation technique.
