Abstract: |
Based on the data of inundated area in 14 regions of Liaoning Province from 1996 to 2005, the characteristics of spatial and temporal distribution and changing tendency of main agricultural disasters (including drought, flood, hail, frost, and plant diseases and insect pests) were analyzed
with statistical method. The results showed that the drought disaster had a greatest influence to agricultural production in Liaoning. The drought disaster was most serious in 2000 with an inundated area of 1.4×105 hm2; the hail disaster was most serious in 1997 with an inundated area of 4.4×104 hm2; the flood disaster was most serious in 1998 with an inundated area of 2.3×104 hm2; the disaster of plant diseases and insect pests was most serious in 1996 and 1997 with an inundated area of 1.3×104 hm2; and the frost disaster was most serious in 1999 with an inundated area of 1.7×103 hm2. The regions suffered severely from agricultural disasters were mainly distributed in west Liaoning. According to the inundated area of agricultural disasters, the regions could be sequenced as west Liaoning > central Liaoning > north Liaoning > south Liaoning > east Liaoning. Drought and hail were the two major disasters affecting agricultural production in iaoning. |
