黑河流域农业用水健康性及其评价方法研究

定性评价了黑河流域农业用水健康性,并对其定量评价方法进行了初步探讨.在提出农业用水健康性科学内涵的基础上,分析探讨了农业用水健康性的评价标准、理论与技术基础.以协调性与效率性为标准,定性判断了黑河流域目前农业用水仍不健康.为进行定量评价,以资源利用效率、用水结构、用水效率和用水综合效益4个方面为准则,初步选择了20项指标作为农业用水健康评价的指标体系.

Research on health and its method assessment in the Heihe River basin for agricultural water consumption

This paper evaluates qualitatively the health for agriculture water use and discusses preliminarily the quantitative evaluation methods in the Heihe River basin. Rational agriculture water use is the key to solve the growing tension of water resources and continued deterioration of the ecological environment, and the health assessment of agricul-ture water use is the base whether reasonable for agriculture water use . The paper analyses the concept of the health of a-griculture water use, explains the evaluation criteria and theoretical and technological base of health assessment for agri-culture water use. According to coordination and efficiency standard, it can evaluate qualitatively that the water use is not healthy. To the purpose of quantitative evaluation, the study takes resources use eficiency, water use structure, water use efficiency and benefit as regulation, selects initially twenty indexes as index system of health assessment for agricul-ture water use.
