土地整治构建绿色发展空间体系

2017-09-04 06:25:50   中国青年网

治理完成后的高标准农田。

易地补充耕地。

整治前,堆积在土地上的矿渣。

治理后,矿渣做成了透水砖。

土地整治是指对田、水、路、林、村进行综合整理,对宜农未利用土地进行开发,对历史遗留损毁和自然灾害损毁土地进行复垦。近年来,随着经济社会发展,我省对土地的需求呈现增长趋势,落实“占一补一、占优补优、先补后占”的占补平衡指标越来越困难,这为土地整治提出了新的要求。

土地整治就像一把刻刀,能雕琢出五彩纷呈的作品,在建设“山水林田湖生命共同体”、构建绿色发展空间体系,以及优化国土空间开发格局等方面,意义重大。为实现布局科学合理的绿色生产空间、生活空间和生态空间,在新一轮土地整治过程中,我省将进行哪些规划?采取哪些措施?记者进行了采访。

固废处置

利用废弃矿渣进行生态修复

富硫矿渣,是因采矿和冶炼而生的固体废弃物,无论是露天堆放还是填埋处理,都会损毁耕地、污染环境,但如果用来生产盐碱地改造专用肥,就能变废为宝。

太原锦华能源科技有限公司,投资1亿多元,对我省弃存的尾矿渣山及污染损毁土地进行实地勘察和科技攻关,研发出一套较为成熟的资源化技术和工业路线,并据此规划设计了《山西废弃矿渣(山)及污染损毁土地综合开发利用项目》。锦华能源董事长张利荣告诉记者,生态修复综合运用工程和生物等整治措施,对硫铁矿烧渣、腐植风化煤、煤矸石、废弃花岗岩碎石、废弃矿石矿渣等,进行分解、分离、分选,提取有价成分,加工成金属铁精粉、硫磺结晶粉、花岗岩骨料、煅烧高岭土等产品;废弃矿渣则用来生产盐碱地改造专用肥,使被占被污土地恢复耕种状态。截至目前,已经在交口等地修复治理压占、损毁土地近3000亩。
