The research of land use and land cover change is a core and focus point for studying on the global changes.Also the research of spatial-temporal features of land use/land cover change is significantly important for better understanding land use/land cover change and environmental management for sustainable development.In order to study the spatial-temporal changes of land use/land cover

the technologies of Remote Sensing and Geographical Information System were used to analyze the spatial dynamical features and temporal dynamical features of land use.Take land use in Hubei province for example

the mathematical methodology for study on land use change was explored and developed.This research focused on the dynamical analysis of spatial-temporal features of land use/land cover change of Hubei province in five years.Firstly

the author made land use dynamic degree map and land use degree change map through defining the land use dynamic degree index and land use degree index.The equation form of land use dynamic degree index is:S=∑nij（dS i-j /S i）×100×（1/t）×100%where S is the dynamic degree of land use（×100）; S i is the total area of the i th land use type before monitoring; dS i-j is the total area of land use type i turn to other one of land use type from the beginning of monitoring to end; t is the monitoring period; The equation form of land use degree change index is: Δ I b-a =I b-I a=∑ni=1A i×C ib )-（∑ni=1A i×C ia ）×100where I a

I b is the synthetical index of land use degree in time a and time b ;A i is the grade index of land use degree; C ia

C ib is the percentage of area for grade i land use degree in time a and b.If Δ I b-a >0

the land use is continuely developing in this region

or the land use is regressing.Secondly

the cultivated land change

forestland change

grassland change and NDVI change were studied in this paper.Thirdly

the mechanism of land use change and its driving forces were discussed and the quantitative approach and track of study on land use/land cover change in China were given in this paper.
