摘要
选取5个指标,运用模糊聚类方法进行了云南金沙江流域作物病虫灾害区划,将该流域划分为3个病虫灾害 区、8个病虫灾害亚区,揭示了该流域病虫灾害的地域差异性,为因地制宜地制定病虫灾害防治规划及减灾防灾措施 提供了科学依据。
In the paper, the author selects 5 index, and uses the method of fuzzy cluster analysis for regionalizing the disaster of crop diseases and insect pests in Jinsha River Basin of Yunnan province. As a result of the regionalization, the paper divides the Basin into 3 disaster regions and 10 disaster sub - regions of crop diseases and insect pests. The study on the regionalization has revealed the regional differences of crops diseases and insect pests in the Basin, and may provide scientific bases for mapping...
