“2024澳门正版资料免费大全”加大地下水保护 2024澳门正版资料免费大全四川拟建244处地下水监测站点

  中新2024澳门正版资料免费大全网德阳11月23日电 2024澳门正版资料免费大全(记者 何浠)四川省地下水开发与保护学术交流会23日在四川德阳举行。四川省水利厅水文水资源处处长陈鹏现场发布《四川省地下水资源监管要素调查评价暨开发利用保护区划项目》成果。

  陈鹏表示,该项目划定了四川地下水、地热能开发禁限采区范围建议方案,并提出管理方案;针对地下工程开挖深度和排水规模提出管控建议方案,提出557个单元备案级别及限值;划定四川省省级地下水战略储备区建议方案,并提出启用预案;将地下水四级单元套合557个水资源管控单元进行地下水资源量计算,最后逐级进行汇总到行政分区、各级地下水资源分区。

  四川素有“千河之省”的美誉,年均水资源总量2565亿立方米,居全国第二;人均水资源占有量2900立方米,略高于全国平均水平;年均地下水资源量580亿立方米,居全国第三,地下水可开采资源量为173亿立方米。

  据悉,近年来,随着严格落实用水总量和用水效率“双管控”要求,四川地下水用水量逐渐降低,仅占用水总量的5%左右。同时启动对地热水、矿泉水、矿坑涌水和施工降水等方面的监督管理,地下水开发与保护工作取得显著进展。

  四川省水文水资源勘测中心主任庄耘天介绍,目前四川加大地下水监测投入已实现130个地下水国家监测站在线监测,后续还拟在重要生态保护区及部分山丘区区域建设244处地下水监测站点。(完)
