中文摘要	为研究围栏封育对伊犁绢蒿(Seriphidium transiliense)荒漠草地的改善情况,利用便携式光谱仪对不同封育年限的围栏内外实测的半灌木伊犁绢蒿、一年生草本叉毛蓬(Petrosimonia sibirica)和短命植物涩芥(Malcolmia maritima)的高光谱数据进行分析。结果表明,伊犁绢蒿、叉毛蓬和涩芥三者在可见光波段具有明显的差异性,与植物生态生理特征有关,可利用350 ~ 680 nm 内三者光谱反射率的差异进行区分; 伊犁绢蒿的红边斜率在不同封育年限下均表现为围栏内大于围栏外,而叉毛蓬的红边斜率表现为围栏内小于围栏外,涩芥在平台处光谱和红边特征上与其生理生态特征无明显相关性。
英文摘要	In order to understand the improvements of enclosure on Seriphidium transiliense desert grassland,the spectrum of 3 half-shrubby species including perennial S. transiliense,annual Petrosimonia sibirica and ephemeral Malcolmia maritime from inside and outside fence after different fencing times were measured by portable spectrometer. The results showed that there were significant difference between these 3 plants in visible spectrum which correlated with the plant ecophysiological characteristics. These 3 plants can be distinguished based on the difference of spectral reflectance between 350 and 680 nm. The red edge slope of S. transiliense inside fence was always greater than that of outside fence no matter how long the enclosure whereas the red edge slope of P. sibirica was contrary. There was no significant correlations between the spectrum at platform or red edge of M. maritimes and its eco-physiological characteristics.
