Climate Change Characteristics of Baise and Suggestions on Urban Adaptation Strategy

利用气候观测数据分析表明,近60a来,百色出现了与全球气候变化背景一致的增暖变化,主要变化特征有:气温明显升高,年降水日数减少,冬季降水量增多,年日照时数减少;高温和干旱频率高,20世纪90年代以来暴雨日数偏多。与广西平均气候变化状况相比,百色的气候变化程度风险低于广西平均水平。预估到本世纪中期,百色气温仍将缓慢升高,干旱和强降水的强度可能加剧。建议科学规划,统筹协调,科学评估城市气候承载力,开展城市适应气候变化风险管理,提升生态气候环境监测及自然灾害预警应急能力,建设生态气候宜居城市。

Based on observations in Baise station,the research showed that in the past 60 years,there has been a warming in Baise which is consistent with the background of global climate change. The characteristics of the changes can be expressed by the significantly increased temperature,the decreasing of annual rain days,the increasing winter precipitation and the decreasing annual cumulated sunshine hours. There are high rates of high waves and droughts along with aincreasing rainstorm days since 1990s in Baise. Comparing with the average climate change in Guangxi,the risk of climate change degree in Baise is lower. It is estimated that the temperature in Baise will continue to rise slowly,and the intensity of drought and heavy rainfall may intensify by the middle of this century. It is suggested that construction of eco-climate livable city should focuses on making scientific plans,coordinating with overall apartments,assessing urban climate carrying capacity and doing risk management of urban adaptation to climate change,improving the ability of climate environmental monitoring and emergency response for natural disaster.
