摘  要：
为了能更好地适应聊城市农业生产结构调整,有针对性地指导农业生产,发挥聊城农业大市的优势,对聊城近52年日照时数的时空变化特征进行研究。利用气候倾向率、趋势系数等方法,依托GIS技术明晰了鲁西平原地区52年日照时数的时空变化特征。以聊城市辖区内8个县(市、区)地面气象观测站1961—2012年逐日日照时数为基础,构建鲁西地区逐月、季度、年度的平均日照时数系列数据集。采用气候倾向率、农业气象学的方法和GIS技术,对鲁西平原地区日照的月、季和年的变化趋势及其空间分布特征进行系统分析。结果表明:鲁西平原地区年际日照时数和四季日照时数均呈减少趋势,各月的日照时数仅4月略有增加,其余月份均呈显著减少趋势;各县(市、区)中主要以位于中部的聊城城区为中心的日照时数减少趋势最为明显、位于东部的茌平、西部的冠县和东北部高唐县减少次之,而西北部的临清和西南部的莘县减幅最小。全年月平均日照时数变化曲线呈单峰型,峰值出现在5月,最少的是12月;四季中均以东北部的高唐最多,向西南方向逐渐减少,春、夏、秋3季是西南部的莘县最少;冬季则是位于南部偏西的阳谷县最少;年平均日照时数以高唐最多,莘县最少。研究结果为合理利用农业气候资源,建设生态农业提供科学依据。

摘  要：
In order to adapt to agricultural production restructure and guide agricultural production inLiaocheng, and give a full play of its agricultural advantage, the author studied the temporal and spatialsunshine variations in the past 52 years. Climate trend rate, the trend coefficient method and GIS technologywere used to clarify the temporal and spatial characteristics of shine of Luxi plains. Based on data of sunshinehours in 1961-2012 of eight counties in Liaocheng, the author constructed time series data set of the number ofdaily sunshine on monthly, quarterly and yearly basis, and analyzed their variation trend and spatialdistribution characteristics. The results showed that: the annual hours of sunshine and the seasonal hours ofsunshine of Luxi Plains both had a decreasing trend, sunshine hours of each month had a slight increase onlyin April and a significant decreasing trend in the rest of the months. Among the counties(cities, districts),sunshine hours in the center of Liaocheng reduced obviously, followed by Chiping in the east, Guanxian in thewest and Gaotang in the northeast, while Linqing in the northwest and Shenxian in the southwest had theminimum decreasing rate. Annual monthly average sunshine time curve showed a single peak, the peakappeared in May, the least was December. Annual monthly average shine hours were the maximum in Gaotangand gradually reduced to the southwest, and were the minimum in Shenxian in spring, summer and autumn,and in Yanggu in winter. Average annual sunshine hours were the maximum in Gaotang and the minimum in Shenxian. The results could provide a scientific basis for the rational utilization of agricultural climateresources and the construction of ecological agriculture.
