Project Trend on Coastal Wetland Change and Prediction Tupu Models

摘要

Land in Qinhuangdao City for the study area, the visual interpretation of the method was used, 2002ETM+ and 2009 Spot remote sensing images were accurately interpreted, and obtained two coastal wetland map information- Through of the changes of coastal wetland during seven years, the dynamic models of coastal wetland area were researched. Finally, the law of coastal wetland area was found in Qinhuangdao City. Driving force factors of land use were processed. The appropriateness was created using Logistic-Markov - Cellular Tupu model. The entire process is integrated, mapped and grided. First Classification of individual has forecasted, further comprehensive analyzed, so prediction accuracy has been increased. Coastal wetland forecast about quantity, spatial distribution and its development trend analysis of Qinhuangdao City in 2016.
