Potentiality Evaluation for Revegetation of abandoned lands from coal mining activities based on Support Vector Machine
Activities of excavating coal exscind natural vegetation and deposit stone on the natural land that modified the natural land contribute to waste farmlands. Additionally, pollution of environment, losses of human life, human settlements and the infrastructure are also rising, which certainly demands urgent attention. Revegetation had been considered as a kind of cost-effective means. A reasonab...
متن کاملFactors Associated with Succession of Abandoned Agricultural Lands along the Lower Missouri River, U.S.A
The 1993 flood of the Missouri River led to the abandonment of agriculture on considerable land in the floodplain. This abandonment led to a restoration opportunity for the U.S. Federal Government, purchasing those lands being sold by farmers. Restoration of this floodplain is complicated, however, by an imperfect understanding of its past environmental and vegetative conditions. We examined en...
متن کاملCarbon Sequestration on Mined Lands Supporting Abandoned Grasslands: Soil Organic Carbon Accumulation and Distribution
Reclaimed surface coal mines in the eastern United States are commonly revegetated with grasses and legumes. The productivity and carbon sequestration potential of the vegetation varies with the condition and nature of the mined site and soil. This study was conducted to determine the distribution pattern of soil carbon stock on 9 mined grasslands reclaimed after the passage of SMCRA in 1977. M...
متن کاملRon Laskey: still discovering new lands
Ron Laskey — soon to head a new institute in Cambridge, UK, devoted to the molecular biology of cancer — is probably one of the few scientists to derive inspiration from the French existentialist André Gide. Pinned on the notice board above Laskey’s desk, alongside holiday snaps of his family climbing in the French Alps, is a quotation from Gide: “One does not discover new lands without consent...
متن کاملA GIS Methodology for Assessing the Safety Hazards of Abandoned Mine Lands (AMLs): Application to the State of Pennsylvania
Abandoned mine lands (AMLs) associated with past coal-mining scar Pennsylvania’s landscape with environmental and safety hazards. Reclamation projects eliminate and reduce hazards AMLs pose. Due to the large number of AMLs and limited funds, precedence is given to reclaim the most hazardous sites first. These sites are identified through an assessment process that assigns priorities to AMLs. Ho...
