我国主要草地害虫分布格局研究
Distribution pattern of major grassland pests in China
摘要
Abstract
To gain a deeper insight into the geographical distribution of grassland pests,facilitate precise control,and mitigate ecological impacts,the distribution patterns of ten major grassland pests in China were systematically analyzed based on data from the national grassland pest survey data from 2022 to 2024,using ArcGIS spatial analysis and grid-based methods.The results indicated that the high-occurrence pest areas exhibited a"dual-core"distribution pattern,focusing on the Shaanxi-Inner Mongolia border and the edge of the Junggar Basin in Xinjiang;widespread species Oedaleus decorus asiaticus and Acrida cinerea spread along the Hu Huanyong Line,whereas local species Locusta migratoria tibetensis and Galeruca daurica were limited to alpine valleys and sandy habitats.Altitude gradients and longitude were the dominant drivers of species richness differentiation.Results could provide a theoretical basis for the classification and regional management strategies of grassland pests.关键词
