近50年山东省农业气候资源变化特征
Change characteristics of agricultural climate resources in recent 50 years in Shandong Province, China
摘要
Abstract
Based on the 1961-2010 ground surface data from 90 meteorological stations,this paper analyzed the spatiotemporal change characteristics of agricultural climate resources (e.g.sunshine hours,thermal resources and water) for the growth season of winter wheat and summer maize in Shandong Province.Results indicated that temperature indicators showed a significant rising tendency especially in the winter wheat growth season.Both evapotranspiration and sunshine hours declined obviously,especially for the evapotranspiration in the summer maize growth season,while there was no clear change evidence in rainfall and aridity.Regarding the spatial distribution characteristics,agro-climatic resources presented meridional or zonal increment or decrement in the winter wheat and summer maize growth seasons.In different areas,variation features of agro-climatic resources appeared with distinct differences.In the western Shandong area,temperature indicators showed a slight rising tendency while evapotranspiration and aridity declined significantly.Sunshine hours decreased most significantly in the middle and west southern areas.Precipitation increment was relatively obvious in the winter wheat growth season in the middle and east southern areas and in the summer maize growth season in the middle and southern areas.Thermal resource increases benefited the growth of winter wheat in every phase during the growth period.However,it brought high risks of plant diseases and hot disaster as well.The decrease of sunshine hours was adverse to crop photosynthesis in the growth period while evapotranspiration decrement profited the water retention of soil.关键词
