Analysis of farmland landscape pattern evolvement rule on Zhongjie Friendship Farm

The pattern of the farmland landscape is mainly related to the ecological health of farm field and the yield capacity. This paper studied the characteristics of farmland landscape indexes which include Patch Density, Largest Patch Index, Edge Density, Perimeter-Area Ratio, Landscape Shape Index, Patch Shape Index, Fractal Dimension and the relationship among these characters and the influence of the yield capacity through taking the planning maps of different times and the existing map of Zhongjie Friendship Farm in Hebei province, as the information source and describing the change of the landscape pattern and anglicizing the landscape pattern indexes. And it indicates that the landscape pattern will become intensive instead of being scattered with the change of natural and social conditions .Characters of the harmony between human beings and the nature and the evolvement rule would be formed gradually.
