- Abstract:
-
Based on the Landsat TM images of 1997 and 2007, the spatial grid was used to display the ecological service value from the view of spatial distribution and spatial structure.The result showed that the ecological service value of Handan was stable in general from 1997 to 2007, but according to the extreme value analysis, the ecological service value showed a descent trend, which might be induced by the increase of construction land and the decrease of the cropland and water body. From the view of spatial structure, the ecological service value displayed the obvious spatial heterogeneous, the spatial relative strength, nugget effect and spatial heterogeneous were different in different directions.
