摘要
利用南水北调中线水源地(淅川、邓州、西峡和内乡)1971～2007年的气象资料,对水源地的日照、气温、降水等要素的年际、月际变化进行了分析。结果表明:水源地四季分明,雨热同期,冬夏长,春秋短;冬季干旱,夏季降水集中,一年内干湿、冷暖变化激烈。这样的农业气候资源适合各种植物生长,特别有利于中药材、食用菌、小辣椒和猕猴桃等特色农业发展,为水源地的水土保持和水质净化提供了良好的生态环境。
Based on meteorological data of the water sources （Xichuan,Dengzhou,Xixia,Nei xiang） of South-to-north Water Diversion Central Line during 1971-2007,the annual and monthly variety of sunshine,temperature,precipitation,etc.in water source areas were analyzed.The results indicated that the water sources had four distinctive seasons,rainy and hot seasons overlapped each other,summers and winters were long,springs and autumns were short.The winter was dry,precipitation concentrated in summer,changed in wet and dry and changed in temperature were violent.Such an agroclimate suited all kinds of plants,especially distinctive agricultures like traditional Chinese medicinal materials,edible fungi,hot peppers,kiwifruit,etc.This agroclimate provided a good environment for conservation of water and soil and water purification in water resources.
