基于GIS的空间统计分析在奶牛地氟病监测中的应用

    Application of spatial statistical analysis in monitoring cow endemic fluorosis based on GIS

    • 摘要: 目前在动物流行病监测中监测点数量较少,监测数据有限。而利用有限的动物疾病监测数据,分析动物疾病的整体空间分布情况,则需要建立符合动物疾病发展规律的监测预测方法。该文运用空间分析软件ArcGIS9和GEODA软件对A区奶牛地氟病空间分布特征进行了分析,然后建立A区地氟病分布预测图,再与实际分布图进行了叠加分析比较,发现其预测效果较好。这种利用空间统计学研究方法建立的GIS预测模型,可为监测和预测其它与空间相关的疾病提供借鉴。

       

      Abstract: In the monitoring of animal epidemics, the amount of monitoring spots is few and the monitored data limited. Therefore, how to use the limited data to show the general spatial distribution of animal epidemics is the key to build efficient spatial monitoring method. In this paper the GEODA and ArcGIS were used to analyze the endemic fluorosis spatial distribution of district No.A based on the spatial characteristic of the density of cow endemic fluorosis in district No.A, and a prediction model to estimate the cow endemic fluorosis distribution was established. Compared with the true actual distribution, the prediction model had better results in prediction effect. Moreover, the space statistics-related prediction model provides a reference for space-related animal epidemics.
