摘要
随着人口的增长和城市的发展，人类生产、生活活动对武汉市自然地理环境的影响愈来愈大。诸如砍伐森林、围湖垦殖、填湖建房、修建水利工程及城市生产、生活活动等对武汉市自然环境产生了重大影响，并导致了洪涝灾害、湖泊淤积、环境污染等环境问题。但值得指出的是，人类活动对自然环境演变并不起决定作用，它只起一种迭加作用，增强或减弱自然变化的趋势。
Human activities have played more and more important role in the evolution of natural environment.The paper deals with this by demonstrating the influences of five kinds of human activities on natural geographical environment in Wuhan city:1.Cutting down forest causing the soil and water loss.2.Filling the low lands causing the change in geomorphology.3.Reclamation of lakes causing the reduction in their flood storing capacity.4.Building projects distrubing the evolution of river channet.5.Urban activities mainly to result in “the urban hot island”.These factors exert both good and bad effects on natural environment.They oftem cause environmental problems such as flooding,siltation of lakes,etc.But for environment,hurman activity is not always the decisive factor,it merely strenthens or lessens the change of natural environment.
