摘要:

为评价秦岭国家植物园的生态环境质量及其分布特征,基于生态环境状况指数法(EI)和遥感生态指数法(RSEI)对秦岭国家植物园生态环境质量进行了分析。结果表明,秦岭国家植物园EI为72.80,生态环境状况良好,生态功能相对稳定;北部S107省道、光头山、田峪河生态环境质量差,首阳山、晏家山生态环境质量好。EI方法分析的结果可用于生态环境质量的整体评价,而RSEI方法可对分布状况进行评价,这2种方法的结合可为定量评价生态环境质量状况提供良好的方法参考。

Abstract:

In order to evaluate the status of eco-environment quality and the distribution characteristics of Qinling National Arboretum,methods of Ecological Index(EI) and Remote Sensing based Ecological Index(RSEI) were adopted.The results showed that the EI of Qinling National Arboretum is 72.80,which means that the overall ecological environment status is good and the ecological function is relatively stable.In the northern part of arboretum,the nearby of S107 road,the hillsite of Guangtou Mountain and the gulch of Tianyu River,the eco-environment quality is relatively poor;while which of the Shouyang Mountain and the Yanjia Mountain was good.The output of the EI method can be used for an overall evaluation about the eco-environment quality,while the RSEI method can be used to evaluate the spatial distribution of eco-environmental quality.The combination of these two methods provide a good reference for the quantitative evaluation of the eco-environment quality.
