基于BPM-BM算法的地名数据匹配

在对基于过滤方法的中文字符串模糊匹配算法BPM-BM的基本原理、特点和计算流程等进行研究的基础上,与地名数据匹配理论相结合,建立了一种新的地名快速匹配方法。以"全国传染病疫情报告地理信息系统(乡级)建设工程"作为一个具体实例,使用C语言来完成地名数据的匹配。     

吉林省鼠密度的三明治空间抽样模型制图（英文）

Rodents are the main host animals that spread plague, and Spermophilus dauricus(S. dauricus) is the most common rodent in North China. In this study, a rodent density survey was carried out in China's Jilin Province from April to August 2005. Moran's I and semivariogram curves were used to investigate the spatial distribution characteristics of the sampling data. We found that the spatial auto-correlation index was low and failed to generate a meaningful semivariogram curve. In this case, commonly used interpolators, such as kriging, were not suitable for mapping density over the study area. However, the Sandwich model, which is based on spatial stratified heterogeneity, could be applied to our data. Our results showed that the type of soil and land use significantly influenced the distribution of rodent density, and the interactive effect of these variables was much stronger than that of each variable alone. The Sandwich-estimated rodent density map showed that rodent density increased from the southeast to the northwest in Jilin Province. Finally, a framework of a rodent density survey using the Sandwich model was introduced.
