摘 要:文章应用"3S"技术和野外调查相结合方法,对松嫩低平原盐碱地资源现状及其开发潜力进行分区评价。结果表明:研究区现有盐碱地125.6万hm2,轻、中度盐碱地占到盐碱地总面积的70%以上,土壤肥力较高,具有实施"种稻改碱"工程、建设水稻基地的资源优势。杜尔伯特南部、大庆—肇源—肇洲、肇源、泰来片、大安东北、乾安、通榆东北部片、镇赉—泰来等区,盐碱地集中连片,水土资源配置良好,可作为重点开发区规模化发展水稻;大安—通榆—洮南区、镇赉区、林甸区和肇东区的水土资源条件稍差,可适度发展水稻。两者合计具有发展约33.3万hm2水田的资源潜力。大庆—安达—肇州区和通榆—长岭区,草地退化严重,地势相对较高,水资源匮乏,不宜发展水稻,应重点实施草原生态恢复工程。Using the " 3S " technology and combining the field investigation method, this paper evaluated the sa- line-alkali land resources present situation and development potential in Songnen plain. The results showed that the area of saline-alkali land was 1. 256 million hm2, of which light and medium saline-alkali land accounted for over 70%. Due the higher soil fertility, the plain had the resource advantage of establishing rice base. The regions with concentrated saline - alkali lands and good land and water resources, such as Southern Duerbote, Daqing - Zhaoyuan-ZhaoZhou, Zhaoyuan, Tailai, northeast Dantm, QianAn, northeast Tongyu, Zhenlai-Tailai, can be used as a key development zone to large - scale develop rice, while the regions with poor land and water resources, such as Daan-Tongyu-Zhaonan, Zhenlai, Lindian, and Longjiang district, can moderately develop rice. Totally, these regions had about 0. 33 million hm2 potential resources of paddy field. In addition, the regions with serious degra- dation grassland, high terrain and poor water resources, such as Daqing- Anda-Zhaozhou and Tongyu-Changling ar- ea, should focus on the implementation of grassland ecological restoration project.
