【摘要】 本文基于2012年北京房山区洪灾后蚊虫与鼠类密度现场调查数据,应用空间分析与回归分析方法,研究了房山洪水灾后蚊、鼠的空间分布特征、并对其密度与环境因素之间关系进行研究。结果显示:多数行政村内蚊虫与鼠类密度处于低水平状态,蚊虫与鼠类密度的空间聚集趋势并没有空间统计的显著意义;在行政村区域尺度上,蚊虫密度与行政村区域内灯光指数平均值及坡度值成负相关,鼠密度与行政村区域内灯光指数平均值成负相关。更多还原

【Abstract】 Investigation on the spatial distribution of medical vectors after the natural disaster would offer helpful advices on vector controlling as well as staff deployment. In present paper,with field surveillance datasets on mosquito and rodents after blood attack in Fangshan district,Beijing,the spatial analysis and regression were applied to study the spatial allocation and relationship between vector density with environmental factors. As the results,density of mosquito and rodents in larger parts of villages were maintained at low level,and there were no statistical significance could be viewed in spatial aggregations of both the density of mosquito and that of rodents. What’s more,in the scales of administrative village,negative correlation between mosquito density vs. averages lights index and slope degree could be detected,and the rodent density display negative correlation to the average light index.更多还原
