东北林业大学帽儿山实验林场景观格局及破碎化分析
Landscape Pattern and Fragmentation in Maoershan Experimental Forest Farm in Heilongjiang Province
【摘要】 利用东北林业大学帽儿山实验林场1:10 000的林相图(根据 1999年航测照片及 1999年调查材料绘制而成)、1:10 000的土地利用现状图(1999)和实地调查资料,在ARC/INFO支持下,应用地理信息系统技术对帽儿山林场各种景观类型的形状指数、破碎化指数进行了分析:自然景观的形状指数、形状破碎化指数均大于人工景观;景观斑块数破碎化指数取决于斑块的数目。
【Abstract】 In this paper, the authors studied the landscape types and shape index in Maoershan experimental forest farm by means of the GIS supported by ARC/INFO and the maps such as forest type map (1 :10 000) , which is drawn with the aerial photographs and investigation of 1999, and soil utilization map of 1999 (1 :10 000). The shape index and shape fragmentation index of nature landscape are higher than those of artificial landscape; landscape patch fragment index is de-pended on the number of the patch.
