Title: Remote Sensing Information Model for Ecological Quality Assessment in Anhui Province Based on Land Use
Abstract:[Objective]We aimed to establish a more scientific and reasonable ecology evaluation model of remote sensing information in order to provide scientific basis for sustainable development of study area....[Objective]We aimed to establish a more scientific and reasonable ecology evaluation model of remote sensing information in order to provide scientific basis for sustainable development of study area.[Methods]The NDVI(normalized difference vegetation index)and dimidiate pixel model were used to monitor vegetation coverage as the evaluation index of vegetation coverage information;Thermal inertia method was used to inverse soil moisture content in the study area,and it was taken as the index of vegetation coverage information and soil fertility;Soil texture coding image was obtained by visual interpreting,and the soil physical clay content was taken as the index to evaluate compaction situation;The bare land ratio was extracted by linear spectral mixture decomposition model.[Results]The ecological evaluation index system was built from the perspective of land use,and the ecological evaluation remote sensing information model which unit is pixel was established.[Conclusion]The vegetation coverage largely affects the vegetation coverage of study area;the overall evaluation accuracy of this study is improved by 15% more than the traditional methods.Read More
