【防治荒漠化·库布其在行动】“数”说库布其之变:从“不毛之地”到“经济绿洲”

2017-09-20 09:27:22   国际在线

在荒漠化治理过程中,最普遍的做法是通过植树造林等方法“防沙”“治沙”,而鄂尔多斯市同圆库布其生态工业治沙项目却是通过“吞沙”,把沙漠变成资源,实现生态效益的同时创造了巨大的经济效益。

据鄂尔多斯市同圆库布其生态工业治沙有限责任公司常务副总经理李光介绍,这种可以“吞沙”的环保砖是以沙漠风积沙为主原料,工业园区“三废”、煤矸石为辅助原料,按照风积沙、煤矸石、粉煤灰、陶土4:3:2:1的配比,通过天然气以1040摄氏度高温烧结而成的陶土砖。目前,这些陶土砖主要销往周边城市,用于市政建设。

利用独特的资源优势和低廉的天然气价格,库布其环保砖每块的成本仅为0.3元,售价为0.8元,预计实现年均利润总额3750万元。“我们的砖投产时间并不长,但已经有俄罗斯企业和我们洽谈合作,依托库布其的沙漠资源,我们的发展一定会越来越好。” 谈到未来,淖门生充满信心。

甘草种植户吴直花

从2000×1到6000×12:“靠沙吃沙”带来生活红利

“我现在负责200亩左右的甘草种植,一个月就收入6000多块钱呢,我才在这干了6个月,收入已经有3万多了。”贫困户吴直花做梦也没想到,只是在甘草种植示范园里拔拔草、浇浇水就能有这么多的收入,而来这里之前,她靠种玉米,一年的收入才2000多元。

吴直花所在的甘草种植园成立于2013年,由亿利集团投资建设。据亿利资源集团库布其生态事业部副总经理孙永强介绍,库布其产的甘草是乌拉尔甘草,是甘草中最好的品种,“这种甘草适合在沙漠里生长,固氮量大,改土效果明显。可以说,一棵甘草就是一个固氮工厂”。除了甘草本身的固氮价值,在种植过程中,亿利还自创了“甘草平移技术”,让甘草可以躺着生长,1棵甘草治沙的面积由0.1平方米扩大到1平方米左右,绿化效率扩大了十倍。

甘草不仅有极大的生态价值和药用价值,还能进行产业扶贫,给当地百姓带来红利。孙永强说,甘草产业扶贫主要有三种模式:“三到户模式”,即公司提供甘草苗条、技术服务和订单回购“三到户”;“四到户模式”,即公司提供沙漠土地,甘草苗条、技术服务和订单回购;就业扶贫模式。通过这种“产业扶贫、持续造血”的方式,给有劳动能力的贫困户自主脱贫创造条件。2017年以来,亿利已经与431户农牧民签订了半野生化种植65.5万亩的甘草种植合作协议,公司提供的110吨甘草苗条已全部到户。计划种植6520亩,目前已经全部种植完毕,扶贫人数达到5052人。
