城市生物多样性:与野生动物共存的喜忧和挑战

City Biodiversity: The Happiness, Worry and Challenges of Coexistence with Wild Animals

现代城市已经开始出现越来越多野生动物的身影,这是城市生态环境改善的象征,但也给城市管理和居民生活带来了挑战。作为人类活动最集中的区域,城市运行需要消耗大量自然资源,同时排放大量废弃物,对生态环境影响巨大[1]。据统计,占全球土地面积不到3%的城市,消耗了全球60%的淡水资源和76%的木材,排放了全球78%的碳。当前绝大多数生态环境问题,例如环境污染、全球气候变化、生物多样性丧失,都与城市或城镇化相关。

While the occurrence of wildlife in urban environment indicates the improvements of habitat quality and the success in advancing ecological civilization, it also brings challenges to urban biodiversity management.
