摘要:
为研究农牧交错区植被覆盖度的变化，从盐池县1999年、2004年和2010年3期TM/ETM+影像图入手，利用归一化植被指数（NDVI）反演了盐池县的植被盖度，结果表明：1999年、2004年、2010年平均植被盖度分别为24.08%，26.97%和23.92%，总体呈现出现先增加后减少的趋势。对这3 a的植被覆盖度进一步进行分级，发现1999年、2004年、2010年3个时期，低植被盖度所占的比例分别为59.61%，50.75%，62.6%，呈现先减少后增加的趋势；中等植被盖度所占比例分别为34.54%，34.58%，29.20%，呈现先增加后减小的趋势，增加的趋势不明显；高植被盖度所占比例分别为5.85%，14.68%，8.2%，先增加后减小。影响植被覆盖度变化的因素主要有人为及政策因素、气候因素（主要是降水）。
Abstract:
In order to understand the change of vegetation fraction in agro-pastoral transition area, based on TM/ETM+ images in 1999, 2004 and 2010, this study deduced vegetation coverage by using the Normalized Difference Vegetation Index (NDVI) in Yanchi County. It was revealed that the average vegetation coverage in 1999, 2004, 2010 were 24.08%, 26.96%, and 23.92%, respectively, the general trend was decreasing following an increase. The coverage vegetation coverage of these years was further classified. The results showed that the low proportion of vegetation coverage were 59.61%, 50.75%, 62.6% for 1999, 2004, 2010, respectively, showing decrease and then increase; the moderate proportion of vegetation coverage were 34.54%, 34.58%, 29.20%, showing decrease after an increase, and increasing trend was not obvious; the high proportion of vegetation coverage accounted for 5.85%, 14.68%, 8.2%, respectively, showing decrease after an increase. Major factors influencing local vegetation coverage in this area were human activity, policies and climate (precipitation).
