为庆祝《大自然》杂志创刊20周年,去年10月25日,宋庆龄基金会野生生物保护基金管理委员会与本刊共同召开了“中国野生生物资源及其生态环境研讨会”。与会的专家学者就21世纪中国将面临的生态环境问题发表了足以令世人警醒的讲话。从本期起,我们将陆续刊登这些发言内容。 To celebrate the 20th anniversary of Nature magazine, the Soong Ching Ling Foundation Wildlife Conservation Fund Management Committee held a joint seminar on wildlife resources and its environment in China on October 25 last year. Experts and scholars attending the meeting made a speech on the ecological environment that China will face in the 21st century, which is enough to awaken the world. Starting from this issue, we will publish these speeches one after another.
