蒿藜

草本植物花粉与陆缘植被相应，以盐生的蒿、藜科花粉占优势，表明花粉沉积与当地及周边地区植被密切相关。

Corresponding with the epicontinental vegetation , the herb pollen mainly is salt Artemisia and Chenopodiaceae . It shows that pollen deposition is closely related with the vegetation in the vicinity of the research area .

草原区植被的A/C（蒿属/藜科）值较干旱区草原植被为低，分布规律也较干旱区复杂，但仍能反应干旱程度的差别，而且还反映了草原植被的退化程度。

Although A / C ( Artemisia / Chenopodiaceae ) value was lower and more complicated than arid steppe area , it could reflect the humidity and the level of grass degeneration .

落叶阔叶林区灌丛花粉组合中，松蒿比（P/A）大于0.1，而草原及荒漠区灌丛则小于0.1，但草原区灌丛蒿藜比（A/C）大于1，荒漠区则小于1。

However the ratio of Artemisia to Chenopodiaceae ( A / C ) is higher than 1 in steppe area and lower than 1 in desert area .
