【摘要】 以广东省中山市为例,基于SNAP软件和2景Sentinel-2卫星数据,反演并分析中山市全域及特定区域内植被叶面积指数。结果表明,反演结果与中山市生态空间格局和植被保护状况相一致,且与其他研究报道中对水库库区林地采用现场实测方法获得的数据高度一致,表明该方法反演城镇植被叶面积指数具有良好的适用性和准确性。更多还原

【Abstract】 Take Zhongshan city,Guangdong province as an example,based on SNAP software and two scenes of Sentinel-2 data,leaf area index(LAI) of the whole city as well as specific areas was retrieved and analyzed. The retrieval result was consistent with the ecological spatial pattern and the vegetation protection status in Zhongshan city,also it was highly consistent with the field LAI measurement data in other research on forest in reservoir area. The result indicated that this method had good applicability and accuracy in urban LAI inversion.更多还原
