eaodi shahuo fongzhi草地沙化防治(脚ssland desertifieation。ontrol)即草原沙漠化防治，是为控制风沙危害草原而采取的措施。 草地沙漠化是在干旱与不合理利用下，草原生态系统衰退蒸草场沙化哪蘸摹黔翼毅簇其蘸篆鑫鑫薰鑫葬蘸热聋罐罐黔耀蘸粼熟鬓〕摹纂(《中国国矍耀馨……{蘸黔黝…土一演替的过程，是目前全世界面临的重大生态问题之一。现在全球沙漠和沙漠化的土地已达4500多万平方千米，约占陆地总面积的30%，每年还以5~7万平方千米的速度扩大;有10亿人口的生产、生活直接受沙漠化威胁，全世界因沙漠化造成的经济损失一年可达423亿美元以上。中国是沙漠化危害严重的国家之一，全国沙漠与沙漠化土地已占国土总面积的巧.9%，达153万平方千米，近年来还以每年2以x)多平方千米的速度继续扩展。沙漠化危害首当其冲的是草原。 随着草原沙漠化的加剧，草地植被趋于简单化，种类贫乏化，牧草品质劣化，草层的盖度和产量减少，土壤趋于旱化或盐渍化，进而使草原的生产能力和生态功能下降，甚至完全变为毫无生产能力的荒漠。 草原沙漠化一般是在干旱的土壤与气候条件下，由于人为过度放牧、开垦、采挖等因素影响下造成的。其防治亦应采取相应的措施和对策，应遵循全面规划，综合治理，改造与利用相结合;大量种草造林与保护现有植被相结合;生物措施与工程措施相结合;治理措施与管理措施相结合的原则。其主要方法熬 新疆吐鲁番治沙站沙拐枣(王培摄)是:①固定草地使用权。将草地使用权长期有偿固定到农牧户，使草地的管、用、建与责、权、利相统一，以调动千家万户防治草地沙化的主动性和积极性，为其他防治措施的有效实施提供必要的前提与保证。②保护和合理利用现有植被。对可能造成沙化的草地，采取强有力的办法，将草地牧草的利用率控制在50%以内，严防滥牧、滥垦、滥挖，通过“护柴湾”、封沙育林育草、轮休轮牧等措施，保护、恢复原有植被。如内蒙古阿拉善盟草原站，对严重退化的梭梭荒漠草场，经过3年封育后，使每公顷植株密度由以刃株增加到15巧株，平均冠幅由94.6厘米增至320 .7厘米，盖度由8%增至21 .7%，当年生绿色枝条的产量增加4.7~8.9倍。③工程防治。利用柴草、树枝、粘土、石块、板条等，在沙丘上条带状或全面设置直立式或平铺式沙障，以减缓风速，阻滞流沙。
