摘要
对川西北高原沙化典型县（若尔盖县、理塘县）的沙化治理示范工程典型治理模式进行成效调查，总结经验，以期为川西北防沙治沙工程顺利实施提供科学参考。提出针对不同程度沙地的治理策略：轻度沙地（盖度40％以上），通过围栏封育和补播混合草种的方式适当施用有机肥；而中度（盖度25％～40％）、重度（盖度10％-25％）沙化土地除了采用围栏封育和补播草种的方式治理，还需栽植灌木进行固沙；对于极重度（盖度10％以下）沙化土地还需要配置沙障进行固沙。
Investigations were made on the effect of typical management modes of desertification control demonstration project in typical counties （Ruoergai County and Litang County） of the typical desertification control demonstration project, aiming to sum up the experience and to provide scientific reference for the smooth implementation of desertification control projects in Northwest Sichuan. Management strategies were put forward for different degrees of sandy land. Mildly sandy land with above 40% coverage was managed by the way of the enclosure and reseeding of mixed grass and by applying proper organic fertilizen. And as for moderately sandy land with 25% to 40% coverage, and severely sandy land with 10% 25% coverage, in addition to the desertifieation land enclosure and reseeding grasses, the shrub should be planted for sand fixing. The way of managing extremely severe （ less than 10% ） desertification land nee- ded other configurations of sand barriers.
