摘要
本文概述了我国北方地区农业生态系统水分运行及区域分异规律研究的研究内涵及研究战略;提出要通过对我国北方地区农业生态中水分运行和转换规律的综合田间试验及联网研究,确立北方地区农业生态系统水平衡、水循环过程的机制;建立北方地区有限水环境下作物生产力模型;并对北方地区农业生态系统中水分运行与生产可持续发展及其区域分异规律作出评估。
The connotation and strategy of the research on the water movement and its regular regional change in agro-ecosystem of North China are disscussed in this paper. The mechanism of water balance and water cycle process in agro-ecosystem are established. The model of crop productivity in limited water environment condition of North China by means of the combined field experiment and network study of water movement and regular exchange in agro-ecosystem are pro-prosed . The evaluation for water movement and productivity sustainable development and its regular regional change in a-gro-ecosystem of North China are given.
