RS-Based Analysis on Hazards of Prosodes dilaticollis and Topographic Factors:A Case Study in Grasslands in Manas and Hutubi Counties
摘要
Abstract
A good understanding of the relationships between grasslands pests and terrain gradient is essential for grasslands management.In this study,a dynamic monitoring of Prosodes dilaticollis hazards was conducted during the period of 2013-2014 so as to explore the trend of P.dilaticollis hazards along terrain gradients,and the different hazard conditions were classified.Change of the hazard areas in the two years was calculated.On which the elevation,slope,and aspect data were extracted with a digital elevation model,and the characteristics and distribution of the hazards along terrain gradients in the study area were explored.The results showed that,along elevation gradient of 900-1 200 m,the P.dilaticollis hazards were the most serious;the areas with P.dilaticollis hazards were mainly distributed in slope gradient of 0°-8.8°;along aspect gradient,there was no an obvious distribution law of areas with serious P.dilaticollis hazards.关键词
