摘要：

为了定量化评估青龙板栗生长的气象条件,获得科学、可靠的果品认证结果,本研究利用1971—2018年青龙气象站实测数据,对影响板栗生长的温、光、水等气象要素的时间变化进行分析,同时采用DTOPSIS方法,建立气象条件综合评价指标C(0C≤1),并以2008—2018年为例,对板栗气候品质进行认证,将C值与同期的板栗品质进行对比。结果显示：1971—2018年,青龙县年平均气温显著升高、日照减小明显、降水微弱下降;年内1月最冷、降水最少,7月最热、降水最多;45.8%的年份C值≥0.5,C值越大,基本气象条件越适宜板栗生成。板栗品质等级与C值大致存在正相关关系,即果品优质的年份,C值相对较高,这对今后板栗果品的评价和预估具有很好的指示作用。

Abstract:

To quantitatively assess the meteorological conditions for Qinglong chestnut growth, and obtain scientific and reliable fruit certification results, based on the measured data of meteorological station in Qinglong from 1971 to 2018, the temporal variations of climate factors including temperature, sunlight and water were analyzed, and a comprehensive meteorological evaluation index C (0C≤1) was established by DTOPSIS method. Taking 2008 to 2018 as examples, the chestnut climate quality was certified and compared with the C value. The results showed that from 1971 to 2018, the variation of temperature had a significantly increasing trend, precipitation and sunshine hours were decreased, January was the coldest with the least precipitation, July was the hottest with the most precipitation; 45.8% of the years had C≥0.5, the larger the C value, the more suitable the meteorological conditions for chestnut. There was a positive correlation between the quality grade of chestnut and the C value, which had a good indication for the evaluation and prediction of chestnut fruit in the future.
