| 摘 要： | 以新疆天山北坡植被2000-2004年的归一化植被指数为依据,应用灰色预测方法对2005、2006年的地表植被变化情况进行了预测,同时将预测结果划分为7个数值段域,分别对这7个数值区间上的预测精度进行了对比分析,结果表明:研究区域未来2a内,中高植被覆盖度区域的植被衰退减缓,同时INDV≤0.25区域内衰减趋势加剧,减退面积扩大;对地表植被7个数值域的预测中,0.20≤INDV≤0.29的数值段内预测精度最低,平均统计数值为85.34%. |

| Abstract: | A study was conducted to forecast the changes of ground vegetations in the Northern slope of Tianshan Mountains,Xinjiang in 2005 and 2006 based on the Normalized Difference Vegetation Index(NDVI)data during 2000 and 2004 by applying grey forecasting method.The forecasting result was shown in accordance with seven ranges of NDVI,and the forecast precisions for different regions with the seven NDVI ranges were compared.Result indicates that,in two years,the vegetation degeneration in the high vegetation cover... |
