%X Based on Landast-TM remote sensing image of 1999/2000,this article utilized GIS technique to interpret and draw a remote sensing map of Hechi City.Landscape type index(such as number of patches,area of patches,average area of patches,etc.)and landscape index(such as diversity,predominance,evenness,fragmentation,etc.)were used to quantitatively analyse landscape spatial patterns and land use in the study area,and Lorenz curves used to analyze land use collectivity in Hechi City.Results show forest land to be the main land use type in Hechi City in 2000,followed by grass land,farm land,water body,and township and village constructions in that order.Spatial analyses of landscape in the study area reveal that landscape types are both multi-fold and complex.The environment tends to be destroyed by outer disturbances,especially unreasonable human activities.The research results offer a strong basis for sustainable development,utilization,management and design of land resources.It equally lays the foundation for studying the processes of spatial landscape patterns of land use.
