| 摘 要： | 基于江苏盐城湿地珍禽国家级自然保护区核心区2002年LANDSAT影像数据和2010年ALOS影像数据，分别对两期遥感影像进行图像分类比较、图像差值运算、提取影像植被指数，进行图像差值运算等处理，提取保护区核心区地类和植被覆被的相关信息及其动态变化情况，为保护区核心区进一步加强管理与保护提供科学依据。研究结果表明，保护区核心区的人为干扰较小，境内的原生湿地保存完整，生态系统基本实现自我更新，这种情况对于丹顶鹤的保护非常有利。

| Abstract: | This paper was based on the LANDSET image data in 2002 and ALOS image data in 2010 in core area of red-crowned crane reserve in Yancheng wetland of Jiangsu province. Through processing the two remote sensing images with image classification comparison, image difference opera- tion and that after extraction of vegetation index images, the land type and vegetation cover information together with its dynamic changes were extracted, which could provide scientific basis for further strengthening management and protection. Research results show that human disturbance is small in the core area, and the native wetland in the region is intact. Ecosystem can basically realize its self-renewal, which is very favorable for red-crowned crane protection. |
