  • Dynamic analysis and evaluation of Xinjiang forest resources : based on RS and GIS
  • China ; Forest ; Geographical information system ; LANDSAT ; Natural resources ; Remote sensing ; Thematic Mapper ; Xinjiang
  • Based on GIS, related data obtained from satellite remote sensing in 1996 and 2001 were studied through contrastive analysis. Moreover, the dynamic variation of Xinjiang forest resources was studied in an all-around way. The analysis results showed
  • that the forest resources in Xinjiang were increasing on the whole, however, there remained some problems, such as the sparse natural forests, low forest cover rate, imbalanced wood age structure, and mono tree species composition.

  • Satellite remote sensing of forest resources : three decades of research development
  • Bibliography ; Biodiversity ; Forest ; LANDSAT ; NOAA ; Natural resources ; Plant canopy ; Remote sensing ; SPOT ; Sustainable development ; Vegetation dynamics ; Vegetation index
  • This paper reviews how the opportunities provided by satellite remote sensing have been exploited for the collection of information pertaining to forest resources and, building on these experiences, prospects for the future are highlighted. The use
  • of remote sensing in forest resource assessment provides 3 levels of information : the spatial extent of forest cover which can be used to assess the spatial dynamics of forest cover; forest type; biophysical and biochemical properties of forests.

  • The preliminary results of long-term CO2 flux measurements at forest sites in East Asia are explained and compared with each other. The features of seasonal variation of CO2 fluxes are different among deciduous-broadleaf, evergreen-coniferous
  • , deciduous-coniferous and tropical forests in East Asia, and the causes of difference are discussed.

  • Erosion rates surveyed using 230 erosion pins on 24 occasions over 8 years (1994-2001) on forested stream banks, tributaries and forest ditches in the Nant Tanllwyth catchment, part of the Hafren Forest on Plynlimon, mid-Wales, showed statistically

  • The AA. examined forest structure and composition in 4 watersheds in the Selway-Bitterroot Wilderness Area, Idaho and Montana, to better understand the complexity of successional processes following stand-replacing fires in subalpine forest
  • ecosystems. Dendrochronological analyses of more than 1,100 trees were used to identify the timing of establishment of major forest species at sites that had experienced different intervals since the last fire. This was coupled with analyses of forest

  • Forest phenological patterns of Northeast China inferred from MODIS data
  • China ; Forest ; North-Eastern China ; Phenology ; Remote sensing ; Spatial distribution ; Typology ; Vegetation index
  • This paper describes the application of Moderate Resolution Imaging Spectroradiometer (MODIS) time series data for forest phenological patterns. The forest phenological phase of Northeast China (NE China) and its spatial characteristics were
  • inferred using 1-km 10-day MODIS normalized difference vegetation index (NDVI) datasets of 2002. The threshold-based method was used to estimate 3 key forest phenological variables, which are the start of growing season (SOS), the end of growing season (EOS
  • ) and growing season length (GSL). Then the spatial patterns of forest phenological variables of NE China were mapped and analyzed. Results indicate that forest phenological phase from MODIS data is comparable with the observed data.

  • Interspecific variation of bark water storage capacity of three deciduous tree species in relation to stemflow yield and solute flux to forest soils
  • Birch ; Deciduous forest ; Ecosystem ; Forest ; Geo-ecology ; Nutrient ; Oak ; Soil water ; Temperate zone
  • The aim of this study is to couple bark water storage capacity with stemflow production and solute inputs to the forest floor, thereby illustrating the importance of stemflow generation and leaching of nutrient-ions to the geoecology of forest
  • ecosystems. Bark water storage capacity is linked with the geoecology of temperate deciduous forests because stemflow volume and soluble inputs are partly determined by bark water storage capacity.

  • analyzed to reconstruct the long-term fire history of an old-growth deciduous forest in southern Québec. AMS radiocarbon dates from 16 charcoal fragments indicated that forest fires were widespread during the early Holocene, whereas no fires were recorded

  • Simulated effect of a forest road on near-surface hydrologic response and slope stability
  • Agroforestry ; Forest ; Oregon ; Road ; Runoff ; Simulation ; Slope dynamics ; Subsurface flow ; United States of America ; Watershed
  • The aim of this study was to quantitatively test the well-known hypothesis that a near surface permeability contrast, caused by the surface compaction associated with forest roads, can result in diverted subsurface flow paths that produce increased
  • up-slope pore pressures and slope failure. The work presented here is a simulation based effort that focuses on a site within the H.J. Andrews Experimental Forest. It combines physics-based variably saturated subsurface flow with slope variability

  • Soil CO2 concentration and microclimatic parameters were measured at a primary forest and grassland in dry season (August to September 2003) and rainy season (March 2004) in central Amazonia in order to investigate the effects of infiltration

  • Africa ; Central Africa ; Ecological catastrophe ; Ecology ; Landscape dynamics ; Tropical rain forest
  • Today the Central African rain forest is going to be destroyed and suffers by many disturbances. Economical and political crises with long lasting civil wars and thousand of refugees have locally led to a significant decrease of forested area
  • . But research in geo- and biological sciences over the last 30 years have proved that the ecosystem rain forest is not as stable as supposed. It had been dramatically changed by natural variations in climate during the Last Glacial Maximum (LGM) and also during
  • the Holocene. The study demonstrates by many examples from Central Africa in which way the recent rain forest environments were changed in the past. - (IFL)
