| 摘 要： | 四平市农业生产地位突出,但却受干旱灾害的困扰,特别是近几年旱灾已成为四平市农业发展的瓶颈,因此,研究农业干旱的发生规律尤为重要.从东北地区近500 a旱涝分布图中提取等级数据,结合四平市1951-1998年的年降水量和作物生长季(6-8月)降水量的变化特征,揭示了四平地区农业干旱的发生规律,得出四平地区在近一段时期将继续面临农业干旱威胁的结论.

| Abstract: | The status of agricultural production is prominent in Siping City, but the city usually comes in for drought. Especially recent years, the drought is becoming the bottle - neck for agricultural development in Siping. So the studies on the rule of agricultural drought is very important. This paper distills grading data from drought - waterlogging distributing map of the northeast area in the latest 500 years. Using wavelet analysis and combining with the precipitation variation characters of annual and crop- growing season precipitation from 1951 to 1998 in Siping, the paper comes up with the agricultural drought cycle in Siping and draws a conclusion that the threatening of the agricultural drought will last for a period in future. |
