A Methodology for Estimating Leaf Area Index by Assimilating Remote Sensing Data into Crop Model Based on Temporal and Spatial Knowledge被引量:1
《Chinese Geographical Science》2013年第5期550-561,共12页ZHU Xiaohua ZHAO Yingshi FENG Xiaoming 
Under the auspices of Major State Basic Research Development Program of China(No.2007CB714407);National Natural Science Foundation of China(No.40801070);Action Plan for West Development Program of Chinese Academy of Sciences(No.KZCX2-XB2-09)
In this paper,a methodology for Leaf Area Index(LAI) estimating was proposed by assimilating remote sensed data into crop model based on temporal and spatial knowledge.Firstly,sensitive parameters of crop model were c...
