| 摘 要： | 利用1:50000土地利用现状图和1:10000地形图,在Arc GIS和景观结构分析软件Fragstats支持下,运用生态学与景观生态学的基本原理,选取景观斑块数、均匀度、分维数、优势度、破碎度等反映景观空间格局的指数,对大富庵景观格局进行分析。结果表明,林地是景观的基质;裸岩石砾地、居民点与工矿用地、农田的分维数低,破碎度高,受人类活动干扰程度较大;林地分维数高、破碎度低,植被保护较好;研究区多样性较低、均匀度低、优势度高,说明了景观类型并不丰富,异质性不高。

| Abstract: | Based on 1:50000 landscape map and 1:10000 topographic map,using Arc GIS and the landscape analysis program Fragstats,patches numbers,evenness,fractal dimension,dominance and fragmentation were analyzed in the principle of ecology and landscape ecology.It is showed that forest area is matrix with the largest area in the scenic area;barren lands,residential and industrial lands,farmland own low fractal dimension and high fragmentation because of frequent human disturbances;woodland with low fractal dimension and high fragmentation are protected well;low SHDI,low SHEI and high dominance reflect less landscape type and low landscape heterogeneity. |
