| 摘 要： | 因灾减产粮食量是衡量农业自然灾害强度的重要指标。本文探索了农业自然灾害因灾减产粮食量测算的思路和方法,具体测算了云南金沙江流域45个县(市、区)1979-2000年农业自然灾害因灾减产粮食量,并分析了该流域因灾减产粮食量的特点和时空分异性。可为因地制宜地制定农业自然灾害防治规划和防灾减灾提供科学依据。

| Abstract: | The reduced grain yield from disaster is an important index of judging the intensity of agricultural natural disaster. The authors in this paper explored the train of thought and method of calculating the reduced, grain yield from agricultural natural disaster, and calculated quantitatively the reduced grain yield from agricultural natural disaster of 45 counties in Jinsha River Basin of Yunnan Province in 1979 ~ 2000. In addition, the paper analysed the characteristics of the reduced grain yield from disaster and its difference of time and space distribution. The study may provide scientific bases for mapping out the planning of preventing and controlling agricultural natural disaster and the measures of disaster reduction in the light of local conditions. |
