摘要: |
利用新疆环塔里木盆地地区的地理信息数据及气象资料,结合气象要素细网格推算模型和精细化农业气候区划软件的空间分析功能,对影响该区杏树种植分布的主导气候因子和该区杏树种植分布与气候的关系进行研究。结果表明:1)影响该区杏树种植分布的主导气候因子有:3月下旬和4月极端低温、极端温度出现的频率、≥10℃年积温、年极端最低气温、12月—次年3月日均温7℃以下天数;2)将该地区潜在种植分布区划分成4个等级:气候最适宜区、适宜区、次适宜区和不适宜区,并给出了各个气候适宜区的气候因子特征。揭示了新疆环塔里木盆地地区杏树种植的潜在分布及其气候适宜性,从气候适宜度的角度观察,该区杏树生产布局还有待进一步优化。 |

Abstract: |
The major climate factors affecting the distribution of apricot around the Tarim were clarified.The relationship between the distribution of apricot and climate was discussed with the geographic information around the Tarim Basin from national agrometeorological observation stations of China Meteorological Administration (CMA),together with the small grid calculating method of the climate factors and the spatial analysis function of Refinement of the Agricultural Climate Division software.The results indicated that :1) the dominant climate factors which affected apricot growth in the regions around the Tarim were the minimum temperature in late March,April minimum temperature,the frequency of extreme temperatures,the accumulated temperature over 10℃,the annual lowest temperature,the days of daily average temperature ≤7℃ from December to March.The climatic suitable regions to apricot around the Tarim were given based on its appearance frequency.The climate characteristics for apricot were analysed in each region,which revealed the potential distribution of apricot around the Tarim.The results indicated that apricot distribution could be further optimized around the Tarim based on the climatic conditions. |
