| 摘 要： | 国内外有关作物需水研究的进展情况和相关估算方法，包括研究内容、定量估算方法和数学预测方法，通过其分析论述了各方法的主要原理、特点及局限性，并指出了日前作物需水研究领域存在的主要问题是在非均一下垫面条件下，植被与环境以及植被间的相互作用要比均一下垫面复杂得多。目前的计算模式存在着许多假设，普适性不够，难以推广应用，今后需进一步研究的课题与采取的研究思路主要是改进蒸散计算方法。最后简要介绍了一种利用遥感蒸散模型率定通用陆面模式CoLM来估算区域陆面蒸散量以及陆地耗水量的思路。

| Abstract: | The research on crop water requirements makes great sense to water productivity and irrigation water utility, and the enhancement of which is an urgent task for sustainable agriculture development. This paper introduces the current research progress in crop water requirements and their relevant estimation methods, including the study contents, quantitative analysis methods, mathematical prediction methods, research achievements, etc. This paper also discusses the principles, performances and limitations of these methods. Based on the analyzed results above, it is pointed out that the interaction between vegetation growing on heterogeneous underlaying surface and environment is much more complicated than that on homogeneous underlaying surface. Currently, there are many hypotheses in calculation models, their suitability is relatively poor, and the models are difficult to be applied. Therefore, the main task in the future is to improve the calculation method of evapotranspiration. At last, this paper introduces a concept of calibrating land surface model with RS model for estimating the regional land surface evapotranspiration and land water consumption. |
