摘要
立足于黄土高原地区社会经济可持续发展,以实现生态环境良性发展为目标,探讨了水土保持生态环境用水量的内涵,提出了黄土高原地区水土保持生态环境用水量计算框架,以黄山高原地区泾河流域为例,估算其1970-1996年水土保持年生态环境用水量为6.536 8亿m3。研究成果丰富了生态环境用水量的理论研究,可为黄土高原地区生态环境建设和水资源合理利用提供科学的决策依据。
From the point of view of realizing the sustainable soeio-economic development in loess plateau, this paper discusses the definition of the eco-environmental water demand and the framework for computing eeo-environmental water demand in loess plateau, aiming at sustainable development of eco-environment. Taking Jinghe river basin in loess plateau as an exam- ple, the average yearly ecological water ewquirement for soil conservation measures is estmated as 6.5368 × 10^5m^3 in 1970 - 1996. The research not only enriches the theory of the eco-environmental water demand, but also provides a scientific hasis for the eco-environmental construction and the exploitation and utilization of water resources.
