三明市森林资源景观格局分析研究

Research on Landscape Patterns of Forest Resources in Sanming City

运用景观格局指数,依靠GIS技术支撑,对三明市森林资源景观格局进行研究。结果表明,本地区森林资源景观多样性指数、均匀度指数、破碎化指数较低,优势度指数较高,某些单个森林资源景观的破碎化指数增长快,这说明区域内存在有占优势的景观类型,整体森林资源景观较完整,但随着人类干扰强度的增大,系统的开放性越强,斑块越变越小,并呈直线化和直角化趋势。

Researches on landscape patterns of forest resources in Sanming were carried out by using the index of landscape patterns with the support of GIS technology.The result showed that in Sanming region,the diversity index, evenness index and shatter index were all low, the dominance index was a little higher. The shatter index of some single forest landscape （other forests） is rising quickly. All these indicated that dominant landscape types （forests of Pinus massoniana and Cunninghamia lanceolata） exiting in the area, and the forest landscapes were comparatively integrated. But with the increase of intensity of human interference, the system of the opening is strong. Patches tend to getting small and small that present a straight line and right angle appearance.
