We selected the frontier zone of the Longitudinal Range-Gorge Region （LRGR） as study area, based on data collection of LUCC monitored by remote sensing and other related information got by common investigation ways, used spatial information processing technique and analysis method, and explored the LUCC landscape＇s characteristic and its spatial expansion effect in this special area. The purpose of this study is to find out the landscape pattern and its changing trend, and to provide background in- formation for ecology security management in frontier zone of the LRGR. The primary results are as follows： the LUCC pattern in study area exhibits that the forest is the predominant cover type as land- scape matrixes, while other types are patches or mosaic elements. Under this pattern, because of transformation in different types with the time change, they are influenced either by natural environment condition, or by human action. All of the counties or cities along the frontier zone of the LRGR, when considering their different levels of the natural environment conditions, social economic development status and management manner, show that the LUCC spatial expansion pattern is of sub-region convergency characteristics which is different from that of considering the distance length resistance only.
