Analysis of New Wetland and Vegetation Coverage Dynamics of the Yellow River Delta Based on RS and GIS
摘要
Abstract
Remote sensing satellite image data of the Yellow River delta was analyzed by using RS and GIS technology,the dynamic change of the new wetland area and vegetation coverage was studied.The results showed that the trend and speed of land building of the delta is slowing down,the formed land area in the delta is 126.88 hm2 during 1992-2004 and 63.42 hm2 during 2004-2014.The new wetland is based on low coverage vegetation,the area ratio is 69.14%,70.98% and 87.89% separately in 1992,2004 and 2014.The low coverage vegetation area to net land building area of the delta ratio is 92.97% and 96.36% separately during 1992-2004 and 2004-2014.The vegetation coverage of the new wetland is decline sharply during 2004-2014,indicating the degradation of the Yellow River delta’s new wetland.关键词
