- 为明确黑龙江省西部大豆气候生产潜力的时空演变特征，高效利用气候资源指导大豆生产。基于齐齐哈尔市市区及9个县（市）气象站点1981-2023年气温、降水、辐射数据，运用逐步订正法、趋势分析法、统计学建模方法，计算齐齐哈尔地区的大豆气候生产潜力。结果表明，1993-2023年齐齐哈尔地区光合、光温、气候生产潜力分别表现为下降、上升、上升的趋势，与生长季内辐射、气温、降水呈现的规律大致相同，其中降水量对气候生产潜力的影响较大。光合生产潜力均值为7 805.56 kg·hm-2，总体呈现南低北高、西低东高的趋势；光温生产潜力均值为5 511.96 kg·hm-2，总体呈现西高东低的趋势；气候生产潜力均值为8 093.87 kg·hm-2，总体呈现西低东高的趋势。辐射变化对气候生产潜力的影响主要以负效应为主，气温、降水及综合气候资源变化对气候生产潜力均以正效应为主。适量增多曝辐量、增温、增加降水量均有利于提高齐齐哈尔地区的大豆气候生产潜力。
- Abstract:
- In order to clarify the spatio-temporal evolution characteristics of the climatic production potential of soybeans in western Heilongjiang Province and efficiently utilize climatic resources to guide the actual production of soybeans.Based on the temperature, precipitation and radiation data of the urban area of Qiqihar and the meteorological stations of 9 counties (cities) from 1981 to 2023, the climate production potential of soybean in Qiqihar Region was calculated by using stepwise correction method, trend analysis method and geostatistical modeling method. The results showed that photosynthesis, light temperature and climate potential decreased, increased and increased respectively during 1993-2023 in Qiqihar Region, which was roughly the same as that of radiation, temperature and precipitation in the growing season, and precipitation had a greater impact on climate potential. The average photosynthetic potential was 7 805.56 kg·ha-1, showing a trend of low in the south and high in the north, low in the west and high in the east. The average production potential of light and temperature was 5 511.96 kg·ha-1, showing a trend of high in the west and low in the east. The mean climatic production potential was 8 093.87 kg·ha-1, showing a trend of low in the west and high in the east. The influence of radiation change on climatic potential is mainly negative, while the change of temperature, precipitation and comprehensive climate resources has mainly positive effect on climatic potential. Moderate increase of radiation exposure, temperature and precipitation is beneficial to increase the climatic production potential of soybean in Qiqihar Region. There is still a large room for increasing soybean production in this area, and the spatial division of the potential for increasing soybean production is made to provide data support for rational planning of soybean planting spatial layout.
