Title: Analysis of Land Use Pattern in Typical River Basins of Shandong Peninsula
Abstract: Based on RS and GIS techniques,this study analyzed the land use pattern of 12 typical basins in Yantai City by using the classified principle in the land use map of 1996 to interpret the Land-sat TM image of sep.9.2002.RS and GIS software,such as erdas 8.6,Arcview 3.2 and Arcinfo 7.0 were used as an interpretation tools.Landscape is divided into 10 types according to land use and cover classification method.River basin area and river shape index are the most important indices in describing the character of rivers.The patch density,shape index,landscape diversity,and landscape evenness were calculated by using Fragstats3.3.Association and regression analysis were employed to describe the relations between mentioned indices.In the patch scale,the association analysis between the basin area,shape index and six major land use types indicated that there are significant correlations between the relative area of shrub patches and the relative area of non-irrigated cropland patches(at 0.01 level) and the basin area.The association coefficients are 0.843 and 0.796.There are significant correlations between the relative areas of irrigated and non-irrigated cropland patches(at 0.01 levels) and shape index.There is a logarithmic relationship between the relative area of shrub and non-irrigated cropland patches and the basin area,and there is a positive linear relationship between the relative area of irrigated cropland patches and shape index and a negative relationship between the relative area of non-irrigated cropland patches and the shape index.There is a significant correlation(at 0.01 levels) between patch number and basin area,and the association coefficient is 0.987 in landscape scale.There is a positive relationship between the basin area and the patch number.And there is no significant correlation between shape index and other landscape indices.According to above findings we can confirm that the river basin area and river shape index obviously affect the landscape structure of different rivers.The results of studying landscape class area and patch number showed that,though and are dominant in Shandong Peninsula,the area of orchard and vegetable is not evident in river basin.In contrast,the non-irrigated cropland is dominant in area.The changing trend of irrigated cropland showed that it is the response of the local climate,terrain and physiognomy.Yantai City is the important part of Shandong Peninsula and the landscape structure analysis based on the river basins has significant academic and practical meanings.
