四川省什邡市2005～2010年生态环境质量动态评价
|
摘要
为了研究四川省什邡市"十一五"期间生态环境质量状况,分析生态环境质量动态变化原因,使用生态环境质量指数法构建评价指标体系,以土地利用、水资源量、降水量、土壤侵蚀、污染源排放等作为基础数据,运用遥感解译技术和统计学方法,对什邡市生态环境质量进行2005~2010年动态评价。研究结果表明,2005~2010年,什邡市生态环境质量年际变化呈"V"字型,受汶川地震影响2007~2008年生态环境质量明显下降,其余年际间无明显变化;在评价期内,汶川地震是导致什邡市植被覆盖指数和生物丰度指数明显下降的主要因素,占全部变化因素的97%以上;除2008年外,影响什邡市生态环境质量变化的主要因素是环境质量指数和水网密度指数。
In order to study the eco-environmental quality of the Shifang city of Sichuan province during the period of "eleven five" and analyze the change cause of eco-environmental quality.The ecological environment quality index is used to construct the evaluation index system;The land use,water resources,precipitation,soil erosion and pollution discharge are used as basic data;dynamic evaluation is taken on eco-environmental of Shifang city of Sichuan province from 2005 to 2010 by using the remote sensing technology and statistical method.The result shows: from 2005 to 2010,the EI of Shifang city is fluctuant as V type.The EI dropped obviously from 2007 to 2008 due to the impact of Wenchuan earthquake and kept stable in the other years.During the evaluated period,the Wenchuan earthquake is the main factor to cause IBio & IVeg to be dropped obviously in Shifang city,and it occupies more than 97% in all the factors making change,except 2008,the main factors that impact the EI variation is IEnv and IWat.
