- Abstract:
- Landscape pattern analysis is the intuitive way to recognize the evolution of the regional ecological environment. We took the Manas River Basin as study area, and obtained the changes of data relating to landscape pattern indices using ArcGIS and the landscape pattern analysis software Fragstats 3.4 with remote sensing images of 1990, 2000, 2005, 2010 and digital elevation model data as information source. Some methods such as landscape transition matrix, spatial data overlay analysis were used to analyze the main landscape evolution and evolution of landscape pattern characteristics as well as the factors. The primary conclusions were as follows. Land use changed significantly, the landscape pattern concentrated mainly in the transformation of grassland and unused land to farmland and urban and rural, industrial and residential lands. Patch shape trended to simpleness and regularity in general. Topographic gradient feature of the landscape unit transformed significantly, showing that each elevation gradient, slope gradient and slope gradient distribution existed obvious geographical diversity, particularly were closely related to the elevation and slope factors. It was described that land use has become increasingly diverse with the rapid economic development, the scale and intensity also increased, but it impacted the landscape stability and robustness.
