| 摘 要： | 以调查的鸭类数据为例,基于统计方法得到养殖点周围100 m的土地利用类型:水田、旱地和水体以及养殖点到国道的距离、养殖点到铁路的距离、养殖点到湖泊的距离和养殖点到河流的距离等因素与鸭传染病的发生具有相关性。最后用遗传算法获得这7个环境因素的权重,得到鄱阳湖区养殖点的鸭传染病的发生与养殖点离国道的距离,养殖点离河流的距离等有最大的相关性。

| Abstract: | Taking the ducks data investigated as an example,based on statistical methods,different land use types around the culture points within 100 meters were obtained:paddy fields,dry fields and waters,as well as distance from culture points to the national road,distance from culture points to the railway,distance from culture points to the lakes and distance from culture points to the rivers have the relationship with the occurrence of ducks diseases.At last,Genetic Algorithm was used to obtain that weights of t... |
