| Abstract: | Agricultural landscape along the riparian zones is designated as important landscape components for partly controlling water quality, biodiversity, as well as for their aesthetic role in landscapes.Therefore,the change ofagriculturallandscape along the riparian zonesisatthe top ofthe agenda for many policy makers and landscape planners.As a basis for conservation management, sufficient information about landscape structure should be provided. In the present study, we reconstructed the formerlandscape structure and elucidated the changesin landscape patternsduring a period ofabout15 years.Two sets ofmaps were used:a landsat-5 TM image (1987)and landsat-7 ETM image (2002).The frequency index,landscape diversity index and landscape fragmentation index were calculated foranalyses.The results showed that:(1)the areas ofthe irrigated land,river,forest and beach landscape classespresented a decreasing trend while the areasoflandscape classesofpool, paddy fields,dry land and construction land increased.(2) Disturbed by human activity,landscape diversity index increased butlandscape fragmentation index decreased.In short,Human activitieshave had importantinfluences on agriculturallandscape of the riparian zones along the Yellow River in Henan Province. |
