Analysis and prediction of dust storm monitoring by China Environmental Monitoring Station in 2005, the overall level of dust storm in China was low, with more in the West and less in the East. The analysis of dust storm monitoring results by China Environmental Monitoring Station showed that in northern China in 2004, except for Hexi region of Gansu Province, the ecological environment quality of the source area and main transmission path of dust weather had not changed significantly, and some areas had been restored. According to the relevant national identification standards, it is estimated that the sandstorm weather in China will be more in the West and less in the East in 2005, and the overall level is low

it is predicted that in the spring of 2005, the overall level of sand dust weather in China is low, and the frequency and intensity of large-scale sand dust weather will be reduced and weakened. However, the frequency of primary sand dust weather in Hexi, Gansu Province may be different. Where is the future development direction? " With the increasing concerns of these industries, the sand and dust weather is more in the West than in the East

in the source area of sandstorms: there was no significant change in the ecological status of Northern Xinjiang and Alxa, Inner Mongolia in 2004. It is expected that the occurrence of sandstorms in 2005 will be the same as that in 2004; In 2004, the precipitation in Hexi area of Gansu Province was less, and the soil moisture was poor. It is expected that the number of sand dust weather will increase in 2005; In 2004, the vegetation coverage in the central and northern Inner Mongolia and Hunshandake region was good, and it is expected that the number of sand dust weather will decrease in 2005

in the areas of dust storm transmission and enhancement: the ecological conditions in Ningxia and Northern Shaanxi improved in 2004, and the vegetation coverage increased. It is expected that the sand and dust supplement along the road will be weakened in 2005, and the sand and dust weather in the downstream affected areas such as Beijing will also remain at a low level. Comprehensive analysis shows that the overall occurrence level of sand dust weather in spring of 2005 is low

in addition, according to the analysis of monitoring results in recent years, in January, 2005, except for some parts of Xinjiang and western Gansu, the most important use and parameters in northern China: some areas will not be affected by dust weather
