分析引入椭圆坐标，以助于处理问题的边界条件，并最终给出直角坐标下各分量的对应结果，以便于实际应用。
Just like that the core patch which is not adjacent to water and hilly woods has the flat edge , near round shape , high trees diversity and abundant native trees , which can reduce the external disturb and protect the native trees . in addition , the matrix in the landscape is the patch that is flat , not adjacent to water and scatter woods has low fragmentation degree , smooth edge and near ellipse shape , which is adapted to matrix
如，非邻水山地密林团聚分布，边界平滑，呈圆形，树种多样性指数高，当地物种丰富，这种格局能显著降低外部干扰，保护主要当地物种，与核心斑块的功能相适应；非邻水平地疏林斑块边界平滑，近椭圆形，这种格局有利于分散干扰危险，与本底斑块的功能相适应。
