| Abstract: |
| Obtained by using FAO Penman-Monteith model and computing the ratio of potential evapotranspiration to precipitation,the indices to evaluate regional dry-wet status and aridity index play important roles in research of global climatic change.So,the agricultural climatic zones in Hebei Province were divided into semi-humid area in warm temperate zone,semi-humid prone to drought area in middle temperate zone in the mountains of northern Hebei,semi-humid prone to drought area in warm temperate zone in Taihang Mountains and coastal plain,semi-arid area in middle temperate zone in northern Hebei plateau and northern Taihang Mountains,semi-arid area in warm temperate zone in the southern and middle plain,semi-arid prone to drought area in middle temperate zone,on the basis of the primary and secondary indices of climatic band of temperature and aridity index.The agricultural climate division will provide climatic basis not only for agricultural production and water resources utilization but also for daily forecasting and mitigation of agro-meteorological disasters. |
