IKONOS数据在植被景观制图和景观空间格局分析中的应用——以丘陵沟壑区准格尔五分地沟小流域为例

High-Resolution IKONOS Data for Vegetation Landscape Mapping and Spatial Pattern Analysis in Zhunger Hill Region of Inner Mongolia-Wufendi gouge basin as an example

本文利用高分辨率 IKONOS数据 ,绘制了内蒙古准格尔旗五分地沟小流域植被景观图 ,并分析不同尺度的景观格局。结果表明 :IKONOS遥感数据在大比例尺植被景观制图方面具有较大的应用潜力。格局分析还表明 ,研究区植被景观为典型的人工生态、天然草原和耕地植被的高度镶嵌体 ,人工乔木林是各景观类型中面积最大的一类。整个研究区景观破碎度较大。

In the present paper, we use high-resolution IKONOS data to plot the vegetation mapping at fine scale in Wufendi gouge basin located at Zhunger, Inner Mongolia. Furthermore, we conduct the analysis of vegetation pattern at different levels. Results imply that High-resolution IKONOS data have great much implication on vegetation mapping at fine scale. Analysis for vegetation pattern reveals that vegetation landscape through the study site is a highly mosaic structure of artificial ecological, natural steppe and agrarian vegetation. The arboreal plantation is the largest type among all landscape types. Indices calculation illustrates that Wufendi gouge exhibits a high fractal dimension, probably out of its severe crashed landform and man-made ecological control.
