问题 某线性工程进行生态影响二级评价,成图范围是50km,成图比例尺要求应该()。
选项 A:≥1:100000 B:≥1:50000 C:≥1:10000 D:≥1:5000
答案 A
解析 生态影响评价制图的工作精度一般不低于工程可行性研究制图精度,成图精度应满足生态影响判别和生态保护措施的实施。二级评价的线性工程长度为10~100km,成图比例尺要求≥1:1000000

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
