Monitoring And Analysis Of The Temporal And Spatial Changes Of Landscape Pattern Of The Watershed Of Daling River

The landscape pattern study is focused on the core issue of landscape ecology, especially in the watershed landscape pattern dynamics research can reveal a wide range of ecological process within the evolution of the law.The rise of remote sensing technology, provides a new opportunity for studying the dynamical change of landscape pattern of large scale. Based on the three stage of remote sensing digital image, land transfer, land classification map of two DEM as the main data source, in remote sensing and geographic information system technology support, Major studies(1) The TM image synthesis of false color image, after the histogram equalization and spectral enhancement treatment,adopt an alternative approach to image for supervised classification. After completion of the classification using the ERD AS image processing broken polygons, and ultimately get three landscape map.(2) Using ecology software FRAGSTATS extraction the patch characteristics index and Landscape pattern indexes for landscape pattern figure.Applying the ENVI software to analyse area of transfer matrix.Quantitative analysis of the study area landscape pattern how to change.The relationship between the landscape pattern change and the terrain in the study area(3) In the study area based on the analysis of landscape pattern changes, further analysis of the ecological problems facing in the study area, and then the landscape pattern optimization measures are put forward.
