摘要/Abstract

摘要： 摘要：對新疆博州（博爾塔拉蒙古自治州）地區(qū)1958-2005年作物生長季降水資料的分析結(jié)果表明：博州地區(qū)作物生長季降水量存在顯著增加趨勢，特別是20世紀(jì)90年代以來降水偏多年略多于偏少年；降水存在5～7 a、16 a 和30 a 左右的周期變化；90年代以來，由于博河上游地區(qū)5月份降水偏少，而且博河中游地區(qū)第一場"透雨"日期又快速推后以及透雨次數(shù)減少等原因，造成河谷一帶春夏干旱尤為突出；而在6-8月份，博河上游地區(qū)降水量與大雨日數(shù)的顯著增加卻極易誘發(fā)山區(qū)洪災(zāi)；秋季月降水量的普遍增加對作物的采收晾曬不利，但是山區(qū)秋季降水的增加有利于秋水轉(zhuǎn)為春用。

Abstract: Based on the precipitation data from four meteorological stations in Bole Prefecture during 1958-2005, precipitation changes in the growing season of crops were analyzed. The results show that there was a remarkable rise trend for the precipitation in the growing season of crops, with flood years slightly more than drought years since 1990s; the periods of 5-7 years, 16 years, and 30 years were dominant for the mean regional precipitation; the spring-summer drought was very prominent in the Bole River valley since 1990s, which was mainly caused by the precipitation reduction in the upstream of Bole River in May, the delay of the first soaking rain and the decrease of the soaking rain frequency in the midstream of the Bole River. The flood in mountainous area was easily induced by the significant increase in rainfall amount and the frequency of heavy rain from June to August in the upstream of Bole River. The increase in autumn precipitation was unfavorable for crop picking and airing, but it was advantageous for being stored and used in the next spring.
