Ecosystems is survived in the suitable environment which provide appropriately abiotic resources for organism and IUCN have applied abiotic degradation as Criterion C to assess the risk of ecosystems. However, the origin and collapse status of the criterion is vague for assessors, and the results are inconsistent as the response of ecosystems to environment are different. Therefore, the ecological...
Mapping and modeling the complex ecosystems and their changes over time are key issues in spatial ecology, biogeography, ecosystem ecology and biodiversity researches. This paper attempts to propose a simple, practical and automatic method to produce the ecosystem map in mountainous areas by fusing multi-source data and the related knowledge. The multi-source data included the 30m-resolution land...
The world's ecosystems and biodiversity have suffered a great loss as the result of human activities, which considerably attract urgent for the assessment of the biodiversity at ecosystem-level. Thus, the IUCN Council recently adopted a new Red List criteria as a global standard for ecosystem risk assessment, aims to establish a global Red List of ecosystem. Remote sensing is one of the most powerful...
Fractional vegetation cover (FVC) is one of the most critical indicators for herbaceous wetland vegetation status, degradation and desertification process simulations. The dense in time series and high spatial resolution of FVC is required for wetland ecosystem monitoring because of its heterogeneous landscapes and rapid spatio-temporal variations. However, due to the tradeoff in satellite sensor...
The leaf area index is one of key parameters for ecosystem monitoring, global carbon circulation and climate change. At present leaf area index is routinely available from Earth Observation (EO) instruments such as MODIS. However MODIS-derived estimates of LAI require validation before they are utilised by the ecosystem modelling community. The paper presents a validation of the MODIS LAI collection...
