新疆地区作物耗水时空多样性特征分析

新疆地处西部极为干旱内陆区，鉴于干旱区地理环境特征，基于各灌区1952--2008年57年积累长系列相关气象数据，采用最新修正彭曼-蒙特斯（Penman-Monteith）方法，应用非线性和多元线性模型以及时间序列指数平滑法，研究作物耗水量E丁。时空分布特征和变异规律及发展趋势。结果显示，各灌区ET0峰期均发生在春、夏...

Spatial-temporal Diversity of Crop Water Consumption Characteristics in Xinjiang

Xinjiang locate in the extremely arid inland areas in the West China,In view of the geographical and environmental characteristics in arid regions,based on irrigation area of the 57 years(1952-2008) accumulating long series of meteorological data,using the latest Penman-Montes(Penman-Monteith) method,applied multivariate linear model with linear and exponential smoothing and time series,research for material consumption ET0 temporal and spatial distribution and variation of water and development.Results show that ET0 irrigation peak occurs in the spring and summer of June;rendering stage 3 fluctuation of historical change,ET0 for the next several years on the rise;ET0 renders increase or decrease with altitude and latitude interactive diversity,wind speed significantly affect ET0 positive effects and produce an overlay effect.
