内蒙古草地旱灾研究

A study on grassland drought in Inner Mongolia

在充分考虑草地土壤水分亏缺和生产力水平的基础上,构造了草地缺水指数和旱灾评判系数。通过对旱灾评判系数与灾情历史序列的对比分析,确定了旱灾等级指标,并提出了大面积监测草地旱灾的方法,为客观准确地监测草地旱灾提供了科学依据。

Based on the consideration of grassland water shortage and productivity, water shortage index and drought judgment index were presented. Drought ranks were established according to the comparative analysis of drought judgment index and historical series of disaster, and an appropriate method for measuring the large scale grassland drought was brought forwards. It will provide scientific base for correct, objective measurement of grassland drought.
