Abstract:

Settlement of forest pests and diseases for large areas is one of the most pressing challenges for the development of forest insurance.This study,taking the forest areas of east Inner Mongolia,developed a settlement index of forest pests and diseases at the county scale for large areas,based on MODIS-NDVI data,field survey data,and successfully applied it to east Inner Mongolia for the year of 2016.The results show that the proposed settlement index has the advantage of being simple in calculation,wide coverage and time-space continuity,could monitor the serious damage,even the moderate damage for conifer forest effectively.Therefore,the settlement index of forest pests and diseases could provide reference and support for forest insurance.

Key words: MODIS-NDVI, forest pests and diseases, settlement index
