摘要:
该文基于DEM数据提取贵州省地形起伏度，利用TM遥感影像数据的解译结果，运用GIS技术和景观格局分析软件包Fragstats，对贵州省的景观空间格局随地形起伏度的分异特征进行了分析。结果表明：贵州省景观格局随地形起伏度的空间分异特征显著。地形起伏度较低的区域由于人类活动频繁，改变自然景观的力度较大，景观形状差异性大而且比较破碎，景观类型复杂多样，尤其是丘陵地区，各种景观类型相互交错，景观具有较强易变性，但是其多样性丰富，各景观类型之间的连通显著；而在地形起伏度较高的地区，景观类型较为单一，优势景观明显，景观结构相对简单，各类景观之间的连通性较差。除此之外，在不同的地形起伏度带，各类景观内部的差异性较强，在地形起伏度较小的区域，林地、草地等景观类型斑块形状差异较大，连通性不好，聚集度也较小，而聚落、旱地等景观的斑块形状较为规整，连通性也较好，聚集度较高；地形起伏度较大的地区，林地、草地、石漠化等景观类型的斑块形状较为规整，破碎程度较低，连通性较好，景观布局也较为均匀，但是水田、旱地等景观斑块分布零散，景观内部连通性较差。
Abstract:
In this paper, based on the extracted relief from DEM data of Guizhou Province and use of the interpreted results of TM data, the heterogeneity of landscape pattern with relief in Guizhou province was studied by using GIS and Fragstats. The results showed that in Guizhou Province, heterogeneity of landscape pattern with the relief is significant. In the low relief area, because the human activities is frequent and strength of changing the natural landscape is great, there were large differences in the shape of the landscape, landscape was more fragmented and diverse, especially in hilly area, distribution of each type is complex and fugitive. However, it’s diversity is rich, the connectivity between each kind of landscape is significant. In high relief area, landscape types are more single, predominance of the landscape is more obvious, structure is relatively simple, and connectivity between landscapes is poor. In addition, there are strong differences in the interior of each kind of landscape in every relief zone. In low relief zones, the shape difference between patches of several kinds of landscape is obvious, such as woodland and grassland, the connectivity and aggregation of them is lower; but patches shape of settlement and dry land is more structured, the connectivity is high and aggregation is better. In high relief zones, patches shape of woodland, grassland and rocky desertification is well structured, the fragmentation is less, connectivity is better and landscape layout is more uniform, while the patches distribution of paddy land and dry land is scattered, and the internal connectivity of landscape is poor.
