近五十年来赤峰气候变化及其对生态环境的影响

Climate Change of Chifeng in Recent Five Decades and Its Impacts on Ecological Environment

利用赤峰地区近五十年来气温、降水等资料,分析了赤峰地区近五十年来气候的变化趋势,探讨气候变化带来的生态影响。结果表明:赤峰地区20世纪80年代以来进入变暖期,强对流天气频率加大,多暴雨暴雪,出现气候的不稳定性。年平均气温有所上升,主要表现为冬季平均气温上升。从不同层面分析气温、降水、日最高温度、最低气温、平均温度的变化,以及它们对水资源、土壤、植被、农业生产等生态环境的影响。为实施宏观决策、保护环境、利用气候资源等提供科学依据。

Based on meteorological data（temperature and precipitation etc.） of recent five decades,this paper analyses the climate change trend of recent 50 years in Chifeng to discuss the ecological impacts of climate change.The results show that since 1980s Chifeng region entered a warming period which is characterized by increased frequency of strong convective weather,more heavy rain and blizzard and climate instability.The annual average temperature has increased which is mainly characterized by increased average winter temperature.The changes in temperature,precipitation,daily maximum temperature,minimum temperature and average temperature changes are analyzed from different perspectives.Their impacts on ecological environments,such as water resources,soil,vegetation and agricultural production are also studied.This study provides scientific supports to the implementation of macroeconomic policy,environmental protection and use of climate resources.
