【摘要】 人类历史上外来物种的地理引入对区系经济发展有过积极的作用,由于物种地理引入过程中的“入侵”机制,使得引入种不但不能增加原生地生物区系的物种种类,反而减少了它的生物多样性,加速了原生生物区系的物种灭绝速度,引发水土流失,恶化人类生存环境,增大难以逆转的经济损失隐患,进而制约区域经济的可持续发展,对区域经济可持续发展可能会造成严重的潜在危害。为了维护区域经济的可持续发展,必须谨防物种地理入侵。更多还原

【Abstract】 Geography invasion of species may change and destroy the ecosystem of invaded regions,and affect the sustainable development of regional economy.Started on the notion of biota,species and regional economy and based on the analysis of correlation of biodiversity and regional economy,the paper focuses on the harm for sustainable development of regional economy by invasive species that caused by the present blind introduction of species.The paper considers that the sustainable development of regional economy includes the sustainable development of regional system and the sustainable development of economy system in region.Owing to the special mechanism of geography invasion of species,invasive species cannot increase the variety of species in a native biota,but decrease its species richness,and speed up the extinction of species in a native biota,too.Meanwhile,invasive species can also cause a series of environment problems,such as soil and water loss,worsen human being’s living condition,increase the possibility of economic loss,and then inhibit the sustainable development of regional economy.In order to maintain the sustainable development of regional economy,we should attach great importance to the stability of native ecosystem in a biota and its protection,reduce artificial disturbance and destruction,and be cautious about using invasive species to do ecological restoration,enhance the management of species introduction and international cooperation.更多还原
