摘要：

以内蒙古希拉穆仁草原旅游地为研究区,以2000年、2004年、2007年和2009年遥感影像为信息源,辅之以1：5万地形图、1：5万土地利用现状图为参考,在对遥感影像进行解译的基础上,利用RS、GIS 技术及景观格局分析软件,获取相关景观格局指数的变化数据,分析近10 a研究区景观格局的动态变化特点。研究表明：随着时间的推移希拉穆仁草原旅游地的整体景观格局发生了较大的变化,虽然草地总面积没有明显减少,但景观越来越破碎,被旅游干扰强烈分割后的草原斑块岛屿化现象明显加强,生态环境变得更加脆弱。其景观类型间的变化趋势和程度不尽相同,旅游用地面积迅速增长且斑块数量大、分布密集,成为草原旅游地景观趋于破碎的直接诱因。

Abstract:

The article took the tourist area in Xilamuren grassland of Inner Mongolia as study area, with remote sensing images of 2000, 2004, 2007 and 2009 as information source using a 1:50 000 topographic map and 1:50 000 land use map as reference. Through remote sensing image interpretation combination of remote sensing images and ground surveys, the spatial database was established. Acquiring the changes of data related landscape pattern indices using RS, GIS and the landscape pattern analysis software, the dynamic change characteristics of landscape pattern in the last ten years were analyzed. The results show that, with time going, the whole landscape pattern of tourist area in the Xilamuren grassland has taken great changes. The number of patches, patch density, the index of fragmentation and corridor density index were increasing. The mean patch area, aggregation index, the ratio of the largest patch to the landscape area decreased. Although the grass area did not significantly reduce, landscape became more and more broken, the islanding phenomenon of grassland patch intensifies obviously under anthropogenic interference, and ecological environment became more vulnerable. From the changes of landscape constitute, its trend and level of variation among landscape type were different. Under the impact of drought climate, high coverage grassland area decreased in the study area, the middle and low coverage grassland area increased, and the water and wetland area reduced. The rapid growth of tourism land area and its great number of patches as well as intensive distribution directly result in grassland landscape fragmentation. Reasonable regulation of tourist disturbance is the most important task of protecting grassland ecological environment in the future. In this article the dynamic change of landscape pattern was analyzed using remote sensing, GIS and landscape ecology method joining the tourism interference factors, to provide some reference for the ecological environment protection of grassland tourist area.

Key words: Xilamuren grassland, tourist area, landscape pattern, dynamic change
