<正>针对连清制图的多为手212绘制的弊端，提出基于DEM、DRG、DLG叠加的方法制作样地布设图，通过极坐标原理和数据库编程技术生成样木位置图。应用泰森多边形的插值方法绘制森林分布图，结果表明：基于G1S的连清制图技法。方法科学高效、图件美观实用。

Applying the landscape ecological principle and remote sense technology, the paper analyzed the public park landscape structure and pattern in Xuzhou with patch density, landscape fragmentation index, the fractal dimension index, the nearest neighbor index and the landscape cohesion. The result shows that the distribution and structure of the public park in Xuzhou isn’t much reasonable, the contagion is higher and the fractal dimension index is smaller. At last, the corresponding strategies are put forward.
