| Abstract: | Under the influence of human beings and climate change,the landscape pattern of the farming-pastoral zone in northern China changed intensively.Although many policies were carried out here,it is still fragile in environment.To analysis the reasons resulting in the change of landscape pattern and provide the strategy optimizing the land use types,we studies the characteristic of change of landscape pattern in middle-scaling.Basing on the RS and GIS technology,maps of land use types was obtained representing ... |
