摘要 近56年來，前郭縣農(nóng)業(yè)氣候資源發(fā)生了顯著變化，對前郭縣的玉米產(chǎn)量產(chǎn)生了顯著影響。研究發(fā)現(xiàn)，玉米的產(chǎn)量變化與生長季內(nèi)的降水量、日照時(shí)數(shù)、積溫和平均氣溫的相關(guān)性較好，其中，玉米產(chǎn)量與降水量的正相關(guān)性最高，即玉米產(chǎn)量越高，所需要的水分就越多；玉米產(chǎn)量與日照時(shí)數(shù)的負(fù)相關(guān)性最高。

關(guān)鍵詞 氣象災(zāi)害；暴雨；干旱

Impact of Agricultural Climate Resources on Maize Yield in Qianguo County

Zhang Lei et al（Qianguo Meteorological Bureau， Qianguo， Jilin 138000）

Abstract In the past 56 years， the agricultural climate resources in Qianguo County have changed significantly， which has had a significant impact on the corn yield in Qianguo County. It was found that the change of corn yield was well correlated with precipitation， sunshine hours， accumulated temperature and average temperature in the growing season， among them， the positive correlation between corn yield and precipitation was the highest， that was， the higher the corn yield， the more water was needed; the negative correlation between corn yield and sunshine time.

Key words Meteorological disaster; Rainstorm; Drought

利用前郭縣氣象局綜合觀測業(yè)務(wù)集成平臺提供的月平均資料，對當(dāng)?shù)赜衩桩a(chǎn)量與溫度、降水、日照時(shí)數(shù)等農(nóng)業(yè)氣候資源進(jìn)行線性趨勢、突變、年代際變化特征等相關(guān)分析，有助于加深對前郭縣近56年來氣候變化的了解和認(rèn)識，提高前郭縣農(nóng)業(yè)發(fā)展水平，對前郭縣的氣候預(yù)報(bào)、預(yù)測也具有重要意義。（剩余3763字）
