全球气候变化下中国亚热带地区柑桔气候适宜性

选取亚热带地区273个气象站1961—2008年逐日气象资料,结合IPCC SRES A2情景下未来亚热带地区温度、降水模拟数据,应用作物气候适宜度模型,对中国亚热带地区柑桔的气候适宜性变化进行了研究。结果表明:柑桔气候适宜度变化受到温度的主导,其空间分布趋势同温度适宜度变化基本一致;未来气候情景下柑桔气候适宜度变化大致呈纬度地带性分布,随着纬度的升高其气候适宜度变化由下降变为上升,可以分为强下降型(Ⅰ)、弱下降型(Ⅱ)、弱上升型(Ⅲ)和强上升型(Ⅳ)4种类型;基本上以温州-金华-浦城-乐平-英山-武汉-石门-吉首-武冈-通道-独山-望谟-广南-屏边-澜沧一线为界,其南气候适宜度有所下降,其北有所上升;亚热带西部柑桔气候适宜度上升较大。

Adaptability of citrus in subtropics of China under future climatic scenario

Based on the 1961-2008 daily meteorological data from 273 stations, and in combination with the simulated temperature and precipitation data under future climate scenario (SRES A2), the climate adaptability of citrus in subtropics of China was studied by using crops climate adaptability model. The variation of citrus climate adaptability was dominated by temperature, and its spatial pattern was basically consistent with the variation of temperature adaptability. Under the future climate scenario, the variat...
