1Remote Sensing of Ecosystem Services:An Opportunity for Spatially Explicit Assessment显示文摘Ecosystem service is an emerging concept that grows to be a hot research area in ecology.Spatially explicit ecosystem service values are important for ecosystem service management.However,it is difficult to quantify ecosystem services.Remote sensing provides images covering Earth surface,which by nature are spatially explicit.Thus,remote sensing can be useful for quantitative assessment of ecosystem services.This paper reviews spatially explicit ecosystem service studies conducted in ecology and remote sensing in order to find out how remote sensing can be used for ecosystem service assessment.Several important areas considered include land cover,biodiversity,and carbon,water and soil related ecosystem services.We found that remote sensing can be used for ecosystem service assessment in three different ways:direct monitoring,indirect monitoring,and combined use with ecosystem models.Some plant and water related ecosystem services can be directly monitored by remote sensing.Most commonly,remote sensing can provide surrogate information on plant and soil characteristics in an ecosystem.For ecosystem process related ecosystem services,remote sensing can help measure spatially explicit parameters.We conclude that acquiring good in-situ measurements and selecting appropriate remote sensor data in terms of resolution are critical for accurate assessment of ecosystem services.FENG Xiaoming FU Bojie YANG Xiaojun Lü Yihe 2010Chinese Geographical Science2010,20,6:18

7Mobile node aware opportunistic routing in dynamic wireless sensor network显示文摘Opportunistic routing(OR) could adapt to dynamic wireless sensor networks(WSNs) because of its inherent broadcast nature.Most of the existing OR protocols focus on the variations of propagation environment which are caused by channel fading.However, a few works deal with the dynamic scenario with mobile nodes.In this paper, a mobile node(MN) aware OR(MN-OR) is proposed and applied to a WSN in the high-speed railway scenario where the destination node is deployed inside a high speed moving train, and the MN-OR not only considers the mobility of node but also utilizes the candidate waiting time induced by the timer-based coordination scheme.Specifically, to reduce the number of duplicate transmissions and mitigate the delay of information transmission, a new selection strategy of the candidate forwarders is presented.In addition, two priority assignment methods of the candidate forwarders are proposed for the general relay nodes(GRNs) and the rail-side nodes(RSNs) according to their different routing requirements.Extensive simulation results demonstrate that the proposed MN-OR protocol can achieve better network performances compared with some existing routing schemes such as the well-known Ad-hoc on-demand distance vector routing(AODV) and the extremely opportunistic routing(ExOR) protocols.Lü Xiaojun Jia Xinchun Han Zongyuan Yang Bo Hao Jun 2016The Journal of China Universities of Posts and Telecommunications2016,23,5:1
