    摘要:

    蒙陜甘寧能源金三角地區(qū)以寧夏寧東,、內(nèi)蒙古鄂爾多斯,、陜西榆林為核心，輻射陜西延安和甘肅隴東地區(qū)，是正在崛起的中國(guó)能源新基地,。為了解該區(qū)域的植被及其動(dòng)態(tài)變化,，采用2000～2009年SPOT衛(wèi)星VEGTATION遙感數(shù)據(jù)，對(duì)蒙陜甘寧能源金三角地區(qū)的植被覆蓋變化狀況進(jìn)行了遙感監(jiān)測(cè)和動(dòng)態(tài)分析,。結(jié)果顯示：金三角地區(qū)2000～2009年植被覆蓋度總體呈增加趨勢(shì),，這與區(qū)域內(nèi)近年來(lái)所實(shí)施的生態(tài)保護(hù)工程有關(guān)。其中,，2008年最高,，為45.45%，2000年最低,，為33.74%,，2005年和2009年略有下降。部分區(qū)域植被蓋度降低的主要原因?yàn)槌鞘袛U(kuò)張和區(qū)域資源開(kāi)發(fā),。

    Abstract:

    The “Golden Triangle” of MSGN (Inner Mongolia, Shaanxi, Gansu, Ningxia), a region with abundant energy resources, is a new energy base of China. To get the vegetation coverage status and its dynamic change, the 2000～2009 SPOT VEGTATION NDVI (normalized difference vegetation index) of Golden Triangle energy in MSGN region was used to calculate the maximum vegetation coverage in one-year of every pixel, and the variation between ten years was analyzed. Result showed that the FVC (fractional vegetation cover) in Golden Triangle area was increased generally from 2000 to 2009. The highest average value was 45.45% in 2008, and the lowest average value was 33.74% in 2000. The vegetation coverage was declined slightly in 2005 and 2009, and the main reasons were attributed to city expansion and regional resources development.
