Besed on the multi temporal landscape remote sensing study in Fenggang Town,Zhujiang River Delta.The analyzed the relations between transforming activities and landscape elements.A spatial variance,Human Impact Index,was raised to express the spatial distribution of artificial transforming strength.Using this index,mesh sampling method,and geostatistics tool,we studied the landscape human impact conditions during the past 10 yeas,and revealed the spatial characteristics of artificial tran...
