中文摘要基于分形理论,借助地理信息系统(GIS)技术对云南省土壤侵蚀强度空间结构分形进行定量研究,结果表明:云南省土壤侵蚀强度空间结构特征客观存在,微度、轻度、中度、强度、极强度、剧烈6个侵蚀强度等级的周长-面积关系客观存在;云南省土壤侵蚀强度中,极强度水力侵蚀分维最大,为1.605;剧烈水力侵蚀分维最小,为1.540;极强度水力侵蚀斑块镶嵌结构最复杂,剧烈水力侵蚀斑块镶嵌结构最简单;以极强度水力侵蚀斑块镶嵌结构的稳定性最高,为0.105,中度水力侵蚀斑块镶嵌结构的稳定性其次,为0.095,而以剧烈水力侵蚀斑块镶嵌结构的稳定性最低,为0.040;剧烈水力侵蚀的平均形状指数最大,为0.156,微度冻融侵蚀的的平均形状指数最小,为0.067;剧烈水力侵蚀的平均紧凑度最大,为0.554,微度冻融侵蚀的的平均紧凑度最小,为0.237。
英文摘要The f ractal of spatial st ruct ure of erosion intensity in Yunnan Province is discussed in t his paper based on GIS. Some significant conclusions are drawn : (1) A certain relationship between perimeter and area of soil erosion intensity patches objectively exist s for soil erosion intensity in Yunnan Province. (2) Fractal dimensions of soil erosion intensity of Yunnan Province are calculated. It is t he biggest wit h t he very st rength water erosion being 1. 605 , and the smallest with the fierce water erosion being 1. 504. (3) The stability of spatial structure is the highest with the very strength water erosion being 0. 105 ,second with the moderate water erosion being 0. 095 , and the smallest with the fierce water erosion being 0. 040. (4) The aver2 age Shape Index is the highest with the fierce water erosion being 0. 156 ,and the smallest with the micro2degree freeze2thaw erosion being 0. 067. (5) The average compactness is the highest with the fierce water erosion being 0. 554 , and the smallest with the micro2degree freeze2thaw erosion being 0. 237.
