摘要:

为分析气候变暖背景下陕西猕猴桃温度适宜度的变化特征,为陕西猕猴桃产业适应气候变化提供科学依据和参考,提升陕西猕猴桃产业可持续发展能力。根据陕西猕猴桃全生育期温度适宜度函数,分析评价华县、眉县、城固3个代表县1961—2010年的猕猴桃温度适宜度,并利用RCPs排放情景下的气候变化预估数据对2016—2060年的陕西猕猴桃温度适宜度进行预估。研究表明:1961—2010年陕西猕猴桃温度适宜度呈2—3年缓慢波动变化趋势,1992年后猕猴桃温度适宜度呈升高的趋势;未来在中等和高排放情景下,陕西猕猴桃温度适宜度呈缓慢波动上升趋势,且高排放情景下猕猴桃温度适宜度的趋势强度要强于中等排放情景;中等和高排放情景下陕西猕猴桃温度适宜度分布较1961—2010年均有不同程度北移,除渭北东部地区猕猴桃温度适宜度升高较为明显外,关中和陕南的猕猴桃温度适宜度均有所下降,原有的适宜区范围缩小较为明显,且高排放情景下更为显著。未来陕西猕猴桃产业发展可考虑种植适度北移,同时考虑未来增温对猕猴桃产业造成的威胁,尤其是关中和陕南猕猴桃产区猕猴桃温度适宜度存在下降风险,高温热害对猕猴桃的威胁可能逐步上升。研究结果可为今后陕西猕猴桃产业的布局调整提供一定参考。

Abstract:

The aims are to analyze the changes in temperature suitability of Shaanxi kiwifruit under the background of climate warming, provide scientific basis and reference for Shaanxi kiwifruit industry to adapt to climate change, and enhance the sustainable development ability of Shaanxi kiwifruit industry. Based on the temperature suitability function for the entire growth period of kiwifruit in Shaanxi, this study analyzed and evaluated the temperature suitability of kiwifruit in representative counties of Huaxian, Meixian, and Chenggu from 1961 to 2010, and estimated the temperature suitability of kiwifruit in Shaanxi from 2016 to 2060 using climate change prediction data under RCPs emission scenarios. The research results showed that the temperature suitability of Shaanxi kiwifruit showed a slow fluctuation trend of 2-3 years from 1961 to 2010, and the temperature suitability of kiwifruit showed an increasing trend after 1992; in the future, under medium and high emission scenarios, the temperature suitability of Shaanxi kiwifruit will show a slow fluctuating upward trend, and the trend intensity of kiwifruit temperature suitability under high emission scenarios will be stronger than that under medium emission scenarios; under the medium and high emission scenarios, the degree distribution of temperature suitability of kiwifruit in Shaanxi will move northward to different degrees compared with 1961 to 2010. Except that the temperature suitability of kiwifruit in the eastern part of Weibei has increased significantly, the temperature suitability of kiwifruit in Guanzhong and southern Shaanxi has decreased, and the original scope of suitable areas has shrunk significantly, especially under the high emission scenario. In the future, development of Shaanxi kiwifruit industry can consider the moderate northward movement of planting and the threat of future temperature increase to the kiwifruit industry. In particular, there is a risk that the temperature suitability of kiwifruit in Guanzhong and southern Shaanxi kiwifruit producing areas will decline, and the threat of high temperature heat damage to kiwifruit may gradually increase. The research results can provide a certain reference for the adjustment of the layout of the Shaanxi kiwifruit industry in the future.
