| 摘 要： | 在鄱阳湖周围分布着一系列砂山，由于历史时期人为不合理的经营活动，加之该地区特定的自然环境，荒漠化发展迅速，其标志是流沙面积的扩大，对当地群众生产生活构成新的威胁。本文以江西星子县和都昌县砂山为例，运用卫星像片初步分析出星子县流沙面积占其砂山面积的12．08％，都昌县流沙面积比重为20．3％，处于中度荒漠化发展阶段，最后进一步分析了荒漠化发生与发展机制。

| Abstract: | There existed lots of sandy hills around Bouyang Lake, Jiangxi Province, China. Un-der the influence of local physical conditions and irreasonable land use, desertification de-veloped at a risk speed and area of reaction of vegetated dunes got enlarged. Which didharm to the living of local people. This paper took the sandy hills in Xingzi and DuchangCounty, Jiangxi Province as examples, by analyses of satellite image , ratio of sandy hill inXingzi and Duchang county was 12. 08 percent and 20. 3 percent respectively which showeddesertification in Sandy hills got in moderate stage. In further, this paper analysized themechandism of desertification. |
