基于浙江省20个气象站点1961-2010年的逐日气象数据,分析了浙江省农业气候资源的时空分布特征和变化规律。结果表明:气候变暖背景下,浙江省气温显著升高,≥10℃积温增加,气温稳定≥20℃终日延迟,作物气候生长期增长。热量资源要素在空间上具有一定的纬向分布特征。1961-2010年浙江省日照时数年际间呈显著下降趋势,其中以金衢盆地与台州玉环地区减少最为明显;年均降水量增加,降水天数减少,雨日平均降水强度年际间呈明显上升趋势,以舟山及嘉兴-宁波-台州沿海增速最大。沿海岛屿及金衢地区的参考作物蒸散量较高,丽水地区最少。1961-2010年全省平均湿润指数为1.64,整体上表现出增加趋势。本研究结果可为浙江省农业种植区划、生产布局调整及制定气候变化对策提供参考。
基于浙江省20箇氣象站點1961-2010年的逐日氣象數據,分析瞭浙江省農業氣候資源的時空分佈特徵和變化規律。結果錶明:氣候變暖揹景下,浙江省氣溫顯著升高,≥10℃積溫增加,氣溫穩定≥20℃終日延遲,作物氣候生長期增長。熱量資源要素在空間上具有一定的緯嚮分佈特徵。1961-2010年浙江省日照時數年際間呈顯著下降趨勢,其中以金衢盆地與檯州玉環地區減少最為明顯;年均降水量增加,降水天數減少,雨日平均降水彊度年際間呈明顯上升趨勢,以舟山及嘉興-寧波-檯州沿海增速最大。沿海島嶼及金衢地區的參攷作物蒸散量較高,麗水地區最少。1961-2010年全省平均濕潤指數為1.64,整體上錶現齣增加趨勢。本研究結果可為浙江省農業種植區劃、生產佈跼調整及製定氣候變化對策提供參攷。

Based on the daily data from 1961 to 2010 collected from 20 meteorological stations in Zhejiang Province , the spatiotemporal characteristics of agricultural climate resources were analyzed .It was shown that annual mean temperature exhibited a significant increasing trend at 0.27℃per decade .The accumulated temperature above 10℃and temperature-defined growing period were also increased , and the terminate date of 20℃was delayed .The spatial distributions of heat resource presented a downward trend from north to south .The average sunshine hour was larger in the north than that in the south .During 1961 -2010 , sunshine hours showed a significant decreasing trend , especially in Jinqu Basin and Taizhou .The annual precipitation increased , while the rainy days decreased , which indicated that the rainfall intensity increased .ET0 analysis presented an obvious annual change characteristic of“decrease-little fluctuation-increase”.According to the spatial distribution , the high-value center was located in the inland area and Jinqu Basin , while low-value area was located in Lishui .The mean humid index during 1961-2010 was 1.64 with an increasing trend .The present research would provide reference for planting pattern adjustment to cope with climate change in Zhejiang Province .
