【摘要】 利用遥感定量提取技术及植被盖度信息提取模型,通过输水前与输水后喀尔达依地区的两期TM遥感数据植被盖度的对比分析,监测塔河应急输水工程对下游绿色走廊生态环境恢复的效果。结果表明,输水后受水地区植被盖度有较好的恢复;该监测方法技术路线易于实现,且具有宏观、快速、准确的特点,有一定的推广应用价值。更多还原

【Abstract】 <Abstrcat> This paper focuses on how remote sensing technology was employed in investigating the variation of vegetation coverage after an emergent water transportation project was implemented. A comparison of two Thematic Mapper(TM) images of 2000 and 2001 in the lower reaches of Tarim River was used to determine the changes in vegetation coverage before and after implementation of the project. The results show that the vegetation coverage in an affected green belt had clearly recovered. The method has potential for broad application due to its flexibility, accuracy and convenience.更多还原
