  采集XXXXXL196_2222mba智库百科样品311万份 第三次全XXXXXL196_2222mba智库百科国土壤普查完成国家级数据库搭建

  农业农村部最新公布,自2022年第三次全国土壤普查正式启动以来,共采集样点287.2万个,采集样品311万份,目前,已完成国家级数据库搭建。

  第三次全国土壤普查,农业农村部共组织3万余家单位40余万名普查工作者,深入2860个县,足迹北至漠河、南至三沙、东至黑瞎子岛、西至帕米尔高原,对约110亿亩耕地、园地、林地、草地等农用地和部分未利用地土壤取土化验。

  据介绍,此次土壤普查主要包含五大重点任务:

  一是查清土壤现状

  二是查土壤类型

  三是查土壤利用状况

  四是建立土壤档案

  五是制作土壤图集

  第三次全国土壤普查专家技术指导组副组长、中国农业科学院农业资源与农业区划研究所所长 吴文斌:这次普查的全过程、各环节充分利用了地理信息系统、遥感、全球定位系统、云计算等技术,做到全国一盘棋,实现查得准、查得快。

  这次普查还推进专题调查,在盐碱地集中连片、面积超过10万亩的198个县完成了重点区域盐碱地资源调查。目前正在全面推进766个县的盐碱地土壤专题调查。在31个省(自治区、直辖市)布设了2100个国家级土壤生物专题调查典型样点。今年10月底,已完成全部外业调查采样工作。

  第三次全国土壤普查领导小组办公室专职副主任、农业农村部农田建设管理司副司长 杨鹏:目前已完成国家级数据库搭建,累计存储成土环境、土壤利用状况调查信息和影像资料超过2亿条。土壤测试化验信息超过6800万条,启动样本库建设共计划存储约1000万份土壤样品。样品入库进度接近三分之一。
