机场鸟撞防制中的鸟类风险评价

机场的鸟类由于其所处位置的特殊性，会对飞行安全造成一定威胁。各种鸟类因其自身特征，风险大小也各有不同。在实际调查的基础上，建立了风险评价指标体系，构建了机场鸟类风险评价的实用数学模型，给出了一种度量鸟类风险的简单、合理的科学方法，并就具体实例进行了分析研究。计算结果表明，在所有观察到的70种鸟类中，风险很大者占总数的24．29％，风险较大者占30．00％，风险一般者占30．00％，风险较小者占15．71％。其中风险很大和较大的鸟类应是机场重点防治的对象。就各鸟类的单个风险评价指标也给出了定量结果。以上风险分析结果，为鸟类风险评价和机场鸟害防治提供了定量依据。

Bird risk assessment for bird strike prevention and control at airports

The birds at airports are threatening the flight safety for their special living place. Different birds have different risk values because of their features. the objective for this paper is to identify a simple and useful method to evaluate the risk of birds based on some useful mathematic methods. A case study shows how to calculate the risk. The results showed: among the 70 species of the birds we observed in the research region,species of highest risk is 24.29%,of high risk ,30.00%,of average risk,30.00% and of lowest risk,15.71%. The first two kinds are those species needing meliorating at first. The risks of every bird risk index are also calculated. The results can be used as a quantitative basis in evaluation birds and resolving the bird strikes at airports.
