| Abstract: |
| The paper uses such indexes collected by 22 surface stations in Ningxia between 1961 and 2005 as daily temperature and precipitation,and calculated the accumulative temperature above 0℃ and 10℃ and the precipitation.The results show that,with global climate warming the accumulative temperature above 0℃ and 10℃ last 19 years remarkably increased in Ningxia,the isoline of the accumulative temperature above 10℃ moved remarkably toward south,so the warm-liking crops increased in planting area.The durative days of the accumulative temperature increased remarkably,which is beneficial to the growth of crops.The precipitation increased in some dry regions,which is also beneficial to agriculture and stockbreeding,and vegetation can come back. |
