【摘要】 全球物种灭绝速度不断加快,生物多样性丧失和生态系统退化对人类生存和发展构成重大风险。作为这种总体性危机的重要组成部分,中国的生物灭绝现象和生物安全问题也非常严峻:哺乳类动物的灭绝风险高于世界平均水平,高等植物的受威胁物种比例达15%～20%,栽培植物的种质资源下降、作物的野生近缘植物的"野外丧失极为严重",农作物的害虫威胁越来越大,本土家畜家禽尤其是地方土种大量消失,长江流域的鱼类物种可能消失了30%,外来物种入侵也构成较大风险。要有效应对全局性的生物多样性危机和生态系统危机,需要的不只是一般意义上的加强保护,而是整个社会经济系统的绿色变革。更多还原

【Abstract】 With the acceleration of global species extinction,biodiversity loss and ecosystem degradation are posing a major risk to human survival and development. As an important part of the overall crisis,China’s biological extinction and biosafety problems are also serious: China’s extinction risk of mammals is higher than the world average level; the proportion of threatened species in higher plants is up to 15% ～ 20%; the germplasm resources of cultivated plants are declining; the " field loss" of wild relatives of crops is extremely serious; pest threats are increasing; a large number of local livestock and poultry,especially local native species,have disappeared; the fish species in the Yangtze River basin may have decreased by 30%. The invasion of alien species also poses a great risk. In order to effectively deal with the global biodiversity crisis and ecosystem crisis,protection in a general sense is not enough. What we need is a green transformation of the whole social and economic system.更多还原
