摘要:
利用遥感生态指数（RSEI）进行区域生态变化评估，可以及时、快速地获取水土流失区生态环境变化状况。以赣榆为研究区，采用1994年的Landsat TM 5影像和2014年的Landsat 8 OLI影像，评估指标选择可以反映生态质量条件的绿度、湿度、热度及干度4个生态因子，运用主成分分析方法集成上述指标，分析研究区域20 a间生态状况时空变化。结果表明：研究期间，赣榆区RSEI从1994年的0.577上升到2014年的0.639，增幅为10.75%；生态为优良等级所占的面积比例从1994年的42.7%上升到2014年的50.41%，增幅为18.06%，主要发生在西北部丘陵山区。通过对赣榆区的调查分析，以植树造林为主的小流域综合治理措施对生态质量的改善起到了重要作用。
Abstract:
Using the remote sensing ecological index (RSEI) to evaluate the regional ecological changes, we can obtain the ecological environment changes of soil erosion area in time and quickly. Choosing Ganyu as the study area, we also chose 1994 Landsat TM remote sensing images and 2014 Landsat OLI remote sensing images as the data sources. Green degree, humidity, heat and dry degree were extracted as indicators of evaluation model. Combined with principal component analysis method, we analyzed the ecological changes of study area quantitatively and objectively in the past 20 years. The results showed that during the whole study period, the remote sensing ecological index which was 0.577 in 1994 and rose to 0.639 in 2014, an increased by 10.75%; excellent grade of eco-area which accounted for 42.7% of the area in 1994 and rose to 50.41% in 2014, and increased by 18.06%, mainly in the hills and mountains in the northwest. Through the investigation and analysis of the Ganyu District, the comprehensive management of small watershed based on forest planting has played an important role in the improvement of the ecological quality.
