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.

Key words： eco-environment evaluation; EI; RSEI; principal component analysis; Qinling
