【摘要】 采用生态环境状况指数(EI)对旅游景区生态环境状况进行评价。结果表明:1960年、2005年和2009年旅游景区EI值均大于75,生态环境为优;与1960年比2,005年和2009年EI值分别减小0.99和1.50,生态环境逐年变差,并呈加剧之势I;bio、IvegI、ero和Ienv值均分别减小1.43、0.87、1.04和5.05,生物多样性和植被覆盖率在下降、土地退化加快和环境质量在下降I;env值下降幅度最大,环境质量明显变差。更多还原

【Abstract】 Ecological Index(EI) is adopted to evaluate the local eco-environmental status,and the results indicate that,in 1960,2005 and 2009,the EIes of touring scenic area consistently remain above 75,which illustrates the eco-environmental status is excellent.Comparing with 1960,the EIes in 2005 and 2009 decrease by 0.99 and 1.50,respectively,demonstrating that the eco-environmental status of touring scenic area deteriorate gradually and show a worse tendency;Ibio,Iveg,Iero and Ienv reduce by 1.43,0.87,1.04 and 5.05,respectively,which reflects a degeneration of land,biodiversity,vegetation density and environmental quality;especially the decline rate of Ienv is the largest,indicating the environmental quality deteriorates obviously.更多还原
