Ecological Sensitivity Analysis of Beihai City Based on GIS and RS
In this paper,five factors influencing ecological sensitivity were selected by using GIS and RS technologies,including land use/cover change (LUCC),normalized difference vegetation index (NDVI),elevation,aspect,and water buffer in land area of Beihai City,and the ecological sensitivity evaluation of...

| description | In this paper,five factors influencing ecological sensitivity were selected by using GIS and RS technologies,including land use/cover change (LUCC),normalized difference vegetation index (NDVI),elevation,aspect,and water buffer in land area of Beihai City,and the ecological sensitivity evaluation of single factor in the study area was carried out by using the ecological factor scoring method.The weighted superposition method was used to comprehensively evaluate the ecological sensitivity,and the study area was divided into the non-sensitive area,slightly sensitive area,moderately sensitive area,and highly sensitive area.The results show that the ecological sensitivity of the study area decreases from east to west and from north to south.The sum of the non-sensitive area and the slightly sensitive area is 64.30%,and the two areas are mainly distributed in the southwest,with an elevation below 30 m and relatively underdeveloped river networks.The moderately sensitive area accounts for 29.88% and is mainly distributed in Hepu County;the highly sensitive area accounts for 5.82% and is mainly distributed in the northeast mountainous area.The research results can provide a theoretical basis for ecological environment protection,green development,and rational land use planning in Beihai City. |
