新安县气候变化特征及其对农业的影响

利用新安县1979～2008年的气温、降水等资料，分析了新安县近30年来的气候变化趋势，探讨了气候变暖带来的影响。结果表明：新安气候向干暖方向发展，低温日数以每10年5．11d的速度减少；高温日数以每10年2．29d的速度增加；极端最低气温以每10年1．06℃的速度上升：极端最高气温以每10年0．26℃的速度上升；降水量以每10年3．97mm的速度减少；无霜期延长，积温增加；旱涝天气现象发生的概率增大。分析了气候变暖对新安的农业、林业、生态及生活环境产生的不利影响，并提出了相应对策；

Climate Change of Xinan County and Effects on Agriculture

Using Xinan 1979-2008 years temperature, precipitation and other data,nearly 30a trend of climate change of Xinan County was analyzed,and the impact of global warming was discussed. The results showed that: Xinan climate warming, the low-temperature days reduced 5.11 d/10 a; high-temperature days increased at a rate of 2.29 d/10 a; the extreme minimum temperature rised at a rate of 1.06 ℃/10 a;extreme maximum temperature rised at a rate of 0.26 ℃/10 a; precipitation reduced 3.97 mm/10 a;extended frost-free period, accumulated temperature increase; drought weather increased the probability of occurrence. Analysis was made of the new warming of the climate warming and drying to the direction of development of Xinan the agriculture, forestry, ecology and living environment will be adversely affected.
