This article,using the model of land-use conversion matrix and landscape pattern index by the technical means of RS and GIS,quantitatively analyzes the dynamic changing process of landscape pattern in the Xinkai River Basin during the past 33 years(from 1969 to 2001).Results show that(1)the wetlands of Xinkai River Basin had changed to meadow,farmland,sandy land or salina to different degrees with the inerease of population,intensification of land-use practices and changes of hydrological conditions,leading to the converse growth of the vegetation.(2)With severe fragmentized situation in 2001,the average area of the parcels,the maximum area of the parcel and the perimeter of the maximum parcel decreased by 71.02%,71.08% and 64.76% respectively,compared with that of 1969.While the SL increased from 0.78 to 0.93.This research achievement can provide scientific basis for the protection and rational utilization of wetlands in the Basin.
