摘要
探讨了水资源,包括地表水及地下水农田可持续利用的价值核算方法。通过对节水农业冬小麦实验及稻田不同生产方式的案例应用与分析,对不同生产方式及节水农业技术进行定量化比较研究,表明节水农业技术及生态农业型种植模式的水资源利用不但效率最高,经济上合算;也有益于它的可持续利用。证明该方法在农业可持续发展研究中的作用及可行性。
The methods of value accounting for water resources including surface water and groundwater are discussed. Many practical models for wheat and rice production are used to assess the effect of different measures on water use efficiency and economic benefits. It is indi-cated that production system with water-saving technology and eco-agricultural methods had got both high water use efficiency and good economical benefits. Therefore, this system is good for the sustainable use of water resources. The method is feasible to assessing sustain-able development of agriculture.
