为医治荒漠化这个“地球癌症”贡献“中国药方

  增绿增收 治沙治穷(绿色焦点·广泛开展国土绿化行动④

我国北方分布着八大沙漠、四大沙地,在人类活动和气候变暖的共同影响下,上世纪荒漠化和沙化土地面积一度持续扩张,甚至出现“风沙逼近北京城”的威胁。

进入新世纪特别是党的十八大以来,随着国土绿化和防沙治沙工程不断加强,我国北方绿色屏障持续拓展,实现了从“沙进人退”到“绿进沙退”的历史性转变。自2000年以来,全国荒漠化和沙化土地面积连续三个监测期保持“双减少”:全国荒漠化土地从上世纪末年均扩展1.04万平方公里,转变为年均缩减2424平方公里;沙化土地面积由上世纪末年均扩展3436平方公里,转变为年均缩减1980平方公里。大力度推进生态文明建设,增绿又增收,治沙又治穷,中国为医治土地荒漠化这个“地球癌症”,贡献了宝贵的“药方”。

不过,我国仍然是世界上受荒漠化危害很严重的国家之一,北方一些地区沙尘天气不时来袭,防沙治沙形势依然严峻,任务依然艰巨。深入践行绿色发展理念,牢固树立绿水青山就是金山银山的意识,凝聚各方面力量,加快土地荒漠化治理步伐,才能使得沙区更加美丽宜居,实现人与自然和谐共生。
