为提高浙江省早稻生育期（生长季）气候资源利用率，并实现早稻持续稳产与增产。研究利用浙江省66个国家气象站1971—2022年逐日平均气温、降水量、日照等数据，采取线性倾向率、M-K检验等方法，分析了浙江省近52 a早稻生育期（生长季）热量、降水、光照资源的时空变化特征。结果表明，浙江省早稻生育期、生长季平均气温呈西南高、东北低的分布特征，并以0.34℃/10、0.38℃/10 a气候倾向率波动上升，2002年有激增点；浙江省早稻生长季≥10℃积温年平均在2719.1~3286.4℃·d之间，呈西南高东北低，以75.8℃·d/10 a的气候倾向率增加，东北部增速高于西南部地区，热量资源的空间差异呈缩小态势。降水资源年际变化很大，空间分布上均自西南向东北逐步递减，差异显著，早稻生育期和生长季降水量气候倾向率分别以12.2 mm/10 a和14.1 mm/10 a的速率缓慢增加，空间分布呈东北高西南低阶梯状分布，且多为递增趋势。光照资源年际变幅较大，早稻生育期、生长季平均日照时数分别为698.9 h、771.9 h，并以-11.2 h/10 a、-8.9 h/10 a气候倾向率减少。研究结果为提高气候资源利用率、规避气象灾害和分品种科学布局等方面提供气象依据和支撑，实现浙江地区早稻持续增产。

To enhance the utilization rate of climatic resources during the growth season of early rice in Zhejiang Province and to achieve sustained and increased yields, daily average temperature, precipitation, and sunlight data from 66 national meteorological stations in Zhejiang Province spanning from 1971 to 2022 were analyzed in this study. Utilizing methods such as linear trend analysis and Mann-Kendall (M-K) test, the spatial-temporal variation characteristics of heat, precipitation, and light resources during the early rice growing period and growing season over the past 52 years were examined. The results indicate that the average temperature during the early rice growing period and growing season exhibits a distribution pattern characterized by higher values in the southwest and lower values in the northeast. The climate tendency rate fluctuates with increase of 0.34℃/10a and 0.38℃/10a for average temperature for heat accumulation, with a significant increase point observed in 2002. The annual accumulated temperature above10℃ for early rice ranges between 2719.1 to 3286.4℃·d, also displaying a southwest-high/northeast-low gradient with an increasing climate trend of 75.8°C·d/10a; notably, northeastern regions exhibit a faster increase compared to southwestern areas, leading to a reduction in spatial disparities regarding thermal resources. Interannual variability is significant for precipitation resources; their spatial distribution decreases progressively from southwest to northeast with marked differences observed across regions. The climate trends for precipitation during both the early rice growing period and overall growth season show slow increases at rates of approximately 12.2mm/10a and 14.1mm/10a respectively; these trends follow a staircase-like distribution where northeastern areas are wetter than southwestern ones. Light resource availability demonstrates considerable interannual fluctuations as well, and sunshine resources also exhibit large interannual variations with average sunshine hours being 698.9h and 771.9h, respectively, both showing declines at rates of -11.2h/10a and -8.9h/10a.The research findings provide meteorological evidence and support for enhancing the utilization of climate resources, mitigating meteorological disasters, and implementing scientifically informed varietal distribution, and help to achieve a sustained increase in early rice production in the Zhejiang region.
