树冠如塔，叶片似鳞，根抱岩石，挺立峭壁。 崖柏，我国特有珍稀濒危裸子植物。起源于上亿年前的恐龙时代，白垩纪繁盛一时，藏着无可替代的基因资源，被称为"植物大熊猫"。 1892年，崖柏首次被发现。今天重庆市开州区、城口县、巫溪县和四川省宣汉县一带的莽莽山巅，是这一孑遗植物的仅存栖所。 这里，位于大巴山脉南麓、三峡库区腹心，是长江上游重要水源涵养地。 百余年间，气候变化和人类活动加剧，压缩崖柏生存空间。 1998年，因再无科考记录，世界自然保护联盟一度宣布崖柏灭绝。后来，重庆本土科研工作者跋山涉水，在人迹罕至的崖壁上重新发现崖柏野生种群。 水是山之魂，林是水之根。 2016年1月5日，习近平总书记在重庆召开推动长江经济带发展座谈会时指出："要把修复长江生态环境摆在压倒性位置"。 尊重自然、顺应自然、保护自然，构建人与自然和谐共生的地球家园。 新时代，新思想，新实践。 从濒临灭绝到人工扩繁，崖柏走出巴山渝水，扎根17个省份，百万株之巨、百倍级增长。 崖柏重生，生生不息。 绝处逢生 从宣告灭绝到重新发现，成立专门保护区，全面调查、常态监测野生崖柏 车行开州区，盘山而上。海拔1600米，大进镇新元村。 后山，一株崖柏，1 ...

上海超过300个小区 都发现了貉 总数约3000至5000只 给居民带来不少麻烦 昨天（11月30日） 上海本年度"貉口普查" 调查报告发布 近年来 2022-2025年貉密度与貉遇见率变化 这意味着，在现行管理与科普措施的推进下，貉种群已从早期的快速增长阶段过渡至相对平稳阶段，曾广受关注的社区中"貉出没"情况已有显著改 善。"这一变化是我们希望看到的，即城市中既有貉生存，又不会数量泛滥到遭居民频繁目击，为社区带来困扰。"复旦大学生命科学学院教授王放认为， 这一变化意味着综合性管理策略初见成效。 有猫粮投喂小区貉密度超平均值3倍 ▽ 调查发现，社区"貉出没"情况已有显著改善，市民对貉的认知度和容忍度也都有了提高。 貉密度与貉遇见率均有下降 用两个晚上，通过数百名志愿者的参与，搞清貉在上海的基本分布状况，这就是每年"貉口普查"公民科学调查的基本模式。今年，普查范围从去年的8个 行政区拓展到松江、青浦、闵行、长宁、嘉定、金山、宝山、普陀、浦东9区，根据前期线上问卷结果和12345诉件选择了112个小区。7月的两个周六晚， 519人次志愿者走进这些调查点，进行了超过560公里的样线调查。 调查发现，貉在上海的分布区 ...

科技是生态保护的重要工具，让它好用、管用，仍需人类的智慧与耐性。2024年，我们在双桂湖安装了 3套声纹识别设备，24小时捕捉湿地声音，用算法分离鸟鸣、虫鸣、蛙声，识别物种。面对湿地复杂的 声音环境，设备被搞"糊涂"了，我们还得亲自上阵。棕背伯劳的叫声是"吱嘎吱嘎"的，短促急切，特别 难录。为了校准声纹又不惊扰鸟儿，我只能"钉"在芦苇丛里，不发出一点声音。终于，"吱嘎"声响起， 被雨淋得湿透的我，录下了这段纯净的鸣叫。人类的意志力和创造性是机器无法比拟的，人机协同更能 提升效率。 "像保护眼睛一样保护生态环境"。从曾因养殖污染沦为劣Ⅴ类水体，到经退养还湿、生态修复后水质稳 定在Ⅲ类、候鸟数量5年增长5倍，双桂湖以更美丽的景致悦人身心，也以更健康的生态涵养发展之源。 守护湿地，守护湿地潮汐般的律动，就是在守护人与自然和谐共生的未来。 （作者为重庆市梁平区湿地保护中心高级工程师，本报记者沈靖然采访整理） 科技创新为生态环保提供新路径，生态环保则为新技术提供应用场景 "啾啾"——这是白头鹎清亮的鸣叫，"叽呀叽呀"——白颊噪鹛的叫声会更急促……我的工作是用科技闻 声识鸟，比对鸟鸣声纹的变化，分析鸟类的迁徙规律、栖息偏 ...
