摘要:
利用2001-2008年250 m分辨率的MODIS-NDVI数据与景观格局分析软件，对8 a来连江流域的植被覆盖与空间格局变化进行动态分析。结果表明：近8 a来连江流域的较高与高植被覆盖区面积减少而中度与较低植被覆盖区面积增加，即植被覆盖呈总体退化趋势；流域景观破碎程度减少、连通性增强，景观异质性提高，景观趋于多样化和均匀化；流域内各类景观要素在破碎化程度、复杂性和稳定性、空间分布关系、聚集性变化差异明显，其中较高与中度植被覆盖区的空间特征变化对整个流域空间格局动态起主导性作用。
Abstract:
Based on the 250 m resolution of MODIS-NDVI data from 2001 to 2008, as well as combining with landscape pattern software (FRAGASTAT), the characteristics of dynamic changes and spatial pattern of vegetation cover were analyzed in the past 8 years in this paper. Results show that vegetation cover is degrade trend of whole watershed nearly 8 years, while upper and high vegetation cover decreased, middle and lower vegetation cover increased. The analysis of the landscape pattern indicated that the number of patches decreased continuously, fragmentation decreased slightly, and the degree of diversity, equality and connectivity of landscape increased. The landscape pattern developed towards diversity and equality. It is obvious difference of fragmentation, complexity, stability, aggregation and distribution about spatial among landscape elements. The results above suggested that upper and middle vegetation cover have significant effect on spatial dynamic change of whole watershed.
