Based on internal and external research literature in recent years

this paper emphatically deal with the utility problems of remote sensing（RS）technique

the new land monitoring technology

in landscape ecological studies.Five research areas were discussed respectively: Structure and pattern study:The attribute description of landscape structure and the utility of quantitative analysis methods need large amount of basic data

therefore the landscape structure and pattern study is the category that RS technique has been used extensively.Using RS technique has also stimulated the development of quantitative methods for landscape structure and pattern study.Choosing and improvement of most landscape indices often used to describe the characteristics of landscape pattern

are strictly related to the applicaltion of RS technique. Function study:RS data is mainly used in energy flow study of landscape

combined with field survey information

it can also be used for transferring research of nutrient elements in landscape.Although the application of RS technique in landscape function study has not achieved greatly

but a finite number of literature indicates that RS technique is a reliable tool for different ecological flow study on landscape.Along with its further development

RS technique will produce a strong support to achieve new breakthroughs in ecological function study. Dynamic study:Most of landscape dynamic studies have used RS technique

by integrating the RS data with different kinds of natural

social

economic

and historical information

the landscape changing process can be reconstructed

and the analysis precision can be enhanced greatly.These advantages have contributed a lot to the study of internal driving mechanism of landscape changing. Scale effect study:Scale effect is also a category that RS technique has been used widely.In the study of scale effect by using RS data

a fruitful study area is the scale sensitive analysis of landscape study methods. Because of the he terogeneous characteristics of landscape.it is very important to study the predictability of landscape analysis methods based on RS data in different resolution status. Practice study:Biodiversity conservation and landscape planning are the two typical practice areas of landscape ecology.Because the relationship between landscape attributes and biodiversity characteristics is very complicated

RS technique has become the best tool for landscape scale biodiversity monitoring and species survey.Application of RS technique in landscape planning concentrates mainly in the areas of landscape assessment

landscape simulation

and decision

m

aking support

and often be used together with GIS and other quantitative analysis methods. It can be concluded that the application of RS technique

which has become an important driving force for the deve lopment of landscape ecology

has covered almost all landscape study areas .This technique has significant superiority in landscape study

but its advantages and potentials have not been practiced adequately.Tasks needed henceforth include the extending its using scope

standardization computer assistant survey methods

developing intellectualized landscape analysis system

and stimulating landscape practice study.
