生态农业建设中的水资源生命周期及系统功能响应

Life cycle analysis of water resources and function response in the process of eco agriculture construction

论文从生命周期角度， 对原先自然环境恶劣、 通过生态农业建设取得了良好效果的3个生态农业县的水资源利用进行了全过程研究。结果表明， 水资源生命周期过程的进展情况受多种因素影响。目前， 各生态农业县水资源生命周期过程仍处在发育的初级阶段。这一过程的完整性与系统生态、 经济和社会功能的提高成正比。

 A whole life cycle research on water resources utilization is presented in three eco agricultural counties in which good performances have been gained through the implementation of eco agricultural strategy based on a previously severe natural environmentResults show that the progress of the life cycle of water resources usage is influenced by several factors．The development of the process currently features the initiative status in these counties．The integrity of the cycle will improve the ecologicaleconomic and social functions of ecosystems at direct ratio．
