| 摘 要： | 沟壑密度是反映地表破碎程度的重要因子,在土壤侵蚀、地貌演变等研究中有重要作用。对于沟壑密度的提取方法目前较为复杂,这主要由于在提取过程中所涉及到的因子数目众多,为进一步的空间分析研究设置了障碍。利用图解建模分析方法建立一套沟壑密度提取分析空间数据模型,对沟壑密度的快速提取提供了一套全新的解决方案。最后,以四川省数据为例,采用该分析方法提取出了四川省沟壑密度数据,为进一步研究四川省地形地貌特征奠定了基础。 |

| Abstract: | Ravine density is an important factor of reflecting the Earth＇s surface degree of crushing. It is vital in soil corrosion,evolutionary process of landform and so on.The methods of getting ravine density is complex currently,because this factor is multitudinous in the process of gaining ravine density,this is a hindrance to further spatial analysis.It built a spatial data model of getting ravine density with the method of illustrate modeling analysis,which provided the fire-new solution for extracting ravine density fleetly.Finally,taking Sichuan Province as an example,it had extracted the Sichuan Province ravine density by adopting this method,and it should lay the foundation to researching deep levels topography and landform character of Sichuan Province. |
