摘要
作物生长模型与定量遥感参数的结合,不仅满足前者实现区域应用的需求,也有助于提高后者的反演精度,在生态、农业、资源调查与全球气候变化等研究上意义重大。该文从作物生长模型空间应用拓展的角度,对国内外主流作物生长模型、定量遥感参数以及两者结合的参数与方法进行了概述,分析了典型作物生长模型的主要模拟过程及其驱动、初始化、输出等参数,总结了当前定量遥感正反演结果可为作物生长模型区域应用提供的参数数据;建立了作物生长模型模拟过程与定量遥感参数的对应关系,对比分析了作物生长模型与定量遥感参数的不同结合方式。基于以上内容,对作物生长模型面应用的限制因素及其与定量遥感参数的关系、作物生长模型面应用时参数尺度效应的影响、作物生长模型与定量遥感参数耦合方法的发展3个方面展开了讨论,以期为作物生长模型与定量遥感参数开展更好的结合研究提供参考。
Combining the crop growth models with the remote sensing parameters, is important to realize the applications in the large spatial scale for the former, and also to improve the rationality and accuracy of inversion theory for the latter. Some research fields, such as the ecology, agriculture, resource investigation and global climate change, would use the data derived from the combination form. The overview includes 3 parts, i.e. the international crop growth model, the quantitative remote sensing parameters and the parametric methods. From the view of the spatial expansion for the application of the crop growth model, the development duration of crop growth models was divided into 3 stages： The construction of the mechanism models, the application in the point scale, and the application in the regional and global scale. In order to understand the situation and foundation of the inter-discipline combination from the crop growth simulation and the quantitative remote sensing, the paper describes 3 important contents. The first is overviewing the main simulation processes and the input and output parameters for the typical crop growth models. The second is summarizing the remote sensing inversion parameters which earl be used as the initialization and driving data for the application of crop growth simulation models in the regional and global scale, establishing the corresponding relation between the simulation process of crop growth model and the parameters from the quantitative remote sensing. And the third is comparing 3 kinds of combination methods between the crop growth model and the parameters derived from the quantitative remote sensing, and emphasizing the differences, advantages and disadvantages for the 3 combination methods. Based on the contents mentioned above, 3 topics for discussion are proposed. The first topic is the application limitations of crop growth models in the large spatial scale and its relationship with quantitative remote sensing parameters. The second one is the influence of the sca
