摘要/Abstract

摘要： 以數(shù)值模擬與大規(guī)模網(wǎng)絡(luò)觀測的對比結(jié)果為基礎(chǔ)，通過對"去除"已經(jīng)沙化土地獲得的近地面層粉塵濃度的進(jìn)一步分析，結(jié)合已獲得的亞洲沙塵暴各源區(qū)粉塵釋放量結(jié)果，提出我國的人為沙漠化因素對亞洲沙塵暴的貢獻(xiàn)約為6%的觀點(diǎn)。

關(guān)鍵詞: 亞洲粉塵源區(qū), 沙塵暴成因, 沙漠化對沙塵暴的貢獻(xiàn)

Abstract: On the basis of simulations of emissions and surface concentrations for Asian dust along with validations from a network observation, the anthropogenic related desertification areas within China contribute only about 6% increasing to Asian dust storm. This idea is also derived from the re-assessment of sensitivity test for dust concentration reduction by removing the desertification areas, and simulated dust emission fractions from different Asian dust sources.

Key words: Asian dust sources, dust storm formation, contribution of desertification to dust storm
