【摘要】 文章综合利用了Landsat系列卫星不同传感器(MSS、TM、ETM+)的遥感资料对1979至2004年20多年间的大亚湾周边的植被陆地、非植被陆地以及水域等土地利用类型的相关变化进行了定量监测与评估。遥感监测结果表明,在过去的二十多年间,大亚湾周边植被覆盖总体保持相对稳定,但非植被陆地由1991年的5.1%左右上升到2004年的10.5%左右,水体面积也相应降低了5%左右,表现出“人进水退”的总体变化格局,该变化特征与该区域过去的环境政策、经济活动发展历程有关。通过将人类对区域环境影响的方式、力度和土地利用类型的变化建立一种对应关系,可以预测以后的开发建设活动对土地利用类型的影响,并应用到区域环境影响评价中去。更多还原

【Abstract】 The paper synthesized the remote sensing data obtained by Landsat series satellite(MSS,TM,ETM+) to survey and assess the land utilization,development of vegetated land,non-vegetated land and water area in Daya Bay district from 1979 to 2004.According to the data derived from Landsat in the past two decades the vegetated area around the Daya Bay remained stable while the non-vegetated land rose from 5.1% in 1991 to 10.5% in 2004 and the water area decreased by about 5% correspondingly.It showed a pattern of “human expansion,water retraction” which was highly related with the environmental and economic development in Daya Bay district.By building the relationship between the mode of human’s impact on regional environment,we can predict the impact of developmental action on land utilization and apply it to regional EIA.The study demonstrates that remote sensing can be applied as an effective tool for monitoring the changes of coastal land utilization.更多还原
