| 摘 要： | 利用１９９６年甘肃省沙漠化土地普查资料，对河西地区２０个县（市、区）的土地荒漠化程度进行了评价。结果表明：１９９５年，属于轻度荒漠化的有山丹县、张掖市、肃南县、永昌县、景泰县和玉门市。属于中度荒漠化的有阿克塞县、肃北县、安西县、金昌市、酒泉市、金塔县、嘉峪关市、高台县、临泽县和民乐县。属于严重荒漠化的有敦煌市。高台县在１９９０年以前为严重荒漠化县。属于极严重荒漠化的有武威市、民勤县和古浪县。从评价结果可以看出，河西地区除少数县（市、区）的荒漠化程度较轻外，大多数为中度，严重或极严重荒漠化区域，说明全区荒漠化形势十分严峻。

| Abstract: | Using the general investigation data of sandy desertification in 1996 of Gansu Province the authors we evaluated the land sandy desertification degree of 20 counties(cities or regions) in Hexi region. The results showed: in 1995, Shandan county, Zhangye city Sunan county,Yongchang county Jingtai county and Yumen county belong to slight sandy desertification. Subei county, Akesai county Minle county, Jiayuguan city Anxi county, Jiuquan city, Jinchang city Jinta county, Linzhe county and Gaotai are included in medium sandy desertification. Dunhuang city showed serious sandy desertification. Wuwei city, Minqin county Gulong county are extremely serious sandy desertification regions. From the evaluation result, we can see that most cities, counties and regions except a few counties in Hexi region, are medium, serious and extremely serious sandy desertified, which indicate that the sandy desertification situation in Hexi region is quite out-standing. |
