摘 要:
随着遥感技术的发展，植被指数作为用来表征地表植被覆盖和生长状况的度量参数，已经在环境、生态、农业等领域有了广泛的应用。本文利用中巴资源卫星CBERS-02星CCD1～5波段遥感图像，比较了海岛棉与陆地棉5种植被指数（比值植被指数RVI，归一化差异植被指数NDVI，红色植被指数RI，转换型植被指数TVI，归一化差异绿度指数NDGI）的差异。结果表明：海岛棉与陆地棉的5种植被指数差异均未达到显著性水平（P〉0．05）；海岛棉与陆地棉之间比值植被指数RVI差异最大，而转换型植被指数TVI差异最小；在阿拉尔垦区利用7月份CBERS一02卫星遥感图像植被指数的差异很难区分出海岛棉与陆地棉。[著者文摘]

Abstract:
With the development of remote sensing technology, the vegetation index, as being used for signifying vegetation cover of the earth＇s surface and the parameter of measuring the state of plant growth, is being extensively applied to the fields of environment, ecology and agriculture etc. In this paper, using CBERS- 02 satellite CCD 1 -5 band remote sensing image, five vegetation indexes （RVI, NDVI, RI, TVI, NDGI） were extracted and compared respectively. The result showed that： Differences of 5 kinds of vegetation index between Island Cotton （ Gossypium barbadense L. ） and Upland Cotton （ Gossypium hirsutum L. ） had not reached the significance level. There was the greatest difference of ratio vegetation index （ RVI ） between Island Cotton （ Gossypium barbadense L. ） and Upland Cotton （ Gossypium hirsutum L. ） . On the other hand, the changing type vegetation iiadex （ TVI ） difference was minimum differenct. At Alar reclamation region, it was difficult to distinguish Island Cotton （ Gossypium barbadense L. ） and Upland Cotton （ Gossypium hirsutum L. ） using CBERS- 02 satellite image vegetation index in July.[著者文摘]
