摘要
为评估川滇生态屏障区的自然生态状况,本研究提出了一种基于遥感的川滇生态屏障区生态监测技术。其间选取植被覆盖度、水土流失两个指标作为评价因子,依据归一化差异植被指数生成植被覆盖度,同时结合遥感影像及气象、土壤专题资料,采用中国土壤流失方程计算反映区域水土流失现状的土壤侵蚀强度。以川滇生态屏障区为例,本文评估了2015年、2016年该区域的生态环境状况。试验结果表明,遥感技术能够适用于区域自然生态监测领域。
In order to evaluate the natural ecological status of the Sichuan-Yunnan ecological barrier area,an ecological monitoring technology based on remote sensing for the Sichuan-Yunnan ecological barrier area was proposed in the study.Two indicators of vegetation coverage and soil erosion were selected as evaluation factors,vegetation coverage was generated based on the normalized difference vegetation index,and combined with remote sensing images and meteorological and soil thematic data,the soil erosion intensity reflecting the current status of soil erosion was calculated using the Chinese soil loss equation.Taking the Sichuan-Yunnan ecological barrier zone as an example,the ecological environment of the region in 2015 and 2016 was evaluated.The experimental results show that remote sensing technology can be applied in the field of regional natural ecological monitoring.
