北疆农业热量资源时空变化及其对熟制的影响研究
Spatial-temporal variation of agricultural-heat resources and its impacts on multiple cropping in the North Area of Xinjiang
摘要
Abstract
Based on the annual mean temperature ,frost-free period and accumulated temperature ≥ 10 ℃ from 48 meteorological stations in the north area of Xinjiang from 1961 to 2012 ,the spatial-temporal variation of agricultural-heat resources and its impact on multiple cropping was analyzed using linear regressions ,Mann -Kendall test and Inverse Dis-tance Weighted method .The results showed that the annual mean temperature ,daily meteorological data in frostless peri-od and accumulated temperature ≥ 10 ℃ were increased by 0 .36 ℃ ·10a - 1 ,80 .66 ℃ ·d·10a - 1 and 4 .7d·10a - 1 ( P <0 .01) from 1961 to 2012 ,respectively .They were increased more obviously in Tacheng ,Ili River Valley and Altai than others .Effects of the heat resource became enhanced .The cropping pattern in the North Area of Xinjiang changed from one crop per year to multiple crops per year after 1980s ,which could be demonstrated by the expansion of the area with three crops per year from the central area to the surrounding areas in Tulufan after the year of abrupt changes .The area of two crops per year was expanded to east of Jinghe - Karamay ,most north areas of Karamay - Qitai - hanshan and South Tianshan ,west of Ili River Valley and surrounding areas near Hami City .The integrated heat resources meeting the requirements of three crops per two years were increased slowly ,and counties with one crop per year continued to display-ing a decreasing variation trend toward high latitudes .关键词
