| 摘 要： | 本文以西部测图成果数据为基础,经拓扑检查与纠正、合并、裁剪、拼接、相交及化简等空间数据处理后得到青海省西部两县对比数据,将所得矢量数据转入ArcInfo中,对两期数据进行空间叠置分析,获得土地利用变化的空间数据与属性数据,构建分形指数模型、地类图斑格局指数模型,计算各地类的分形维值、稳定性指数及景观格局指数,根据复杂程度和稳定性指数对两县的地类进行排序,并根据各景观格局指数,分析8年间两县的土地利用格局变化和生态学意义。 |
| 关 键 词： | 杂多县 治多县 分形模型 稳定性 景观格局指数 |

| Abstract: | On the basis of result-data by Western Land Surveying and Mapping,the paper obtained the comparative data of the two counties in western Qinghai Province after spatial data processing such as topology validation and correction,merging,splitting,overlaying,intersecting and simplifying etc.Adding the vector data into Arc Info software,it obtained the spatial data and attribute data of land use change by spatial overlaying analysis.After building fractal indix model and landscape pattern index model,it calculated the fractal dimension,the stability index and the landscape pattern index,each landscape pattern of the two counties was ranked according to the complexity(the fractal dimension D) and the level of stability(Si).Finally it analyzed the change of land use patterns and ecological significance of eight years according to the landscape pattern indices. |
| Keywords: | Zaduo county Zhiduo county fractal model level of stability landscape indices |
