【摘要】 以富裕县1996年和2007年Landsat5遥感数据为基础,以MSAVI植被指数提取为主要方法,结合人工解译,解译出研究区域的草场荒漠化程度分类面积,针对1996~2007年间的荒漠化动态变化,建立动态变化转移矩阵,选用土地覆盖变化和景观生态学的相关指数进行分析。结果表明:荒漠化程度加重,经济的增长和过度的放牧是加重荒漠化的主要原因。更多还原

【Abstract】 Based on 1996 and 2007 Landsat 5 remote sensing data of Fuyu County,using the main method of MSAVI vegetation index,combining with manual interpretation,interpreting the categories area of grassland desertification in study area,aiming at the ten years’ dynamic changes of desertification from 1996 to 2007,establishing the dynamic transfer matrix,choosing the LUCC and landscape index,the underlying index was analyzed.The results showed that desertification become more serious due to the economic growth and overgrazing.更多还原
