摘要
北京前山区是全市果树呈带状集中分布的地区,也是扩大果树面积、提高果品质量的重点地区。研究该地区生态环境特征是十分必要的。热量资源和水资源是生态环境中的主导性因子。本文主要研究北京前山区水资源的现状组成,予测水资源供需平衡特点,以及开发利用价值等方面的问题,为果树带的发展战略提供科学依据。
Beijing lower mountainous area is the concentrated orchard belt area ofthe municipality. It is also an area where importance is attached to theexpansion of orchard coverage and the quality of fruit. It is necessary tostudy the feature of its ecological enviromment. Heat resource of quantityand water resource are the key factors of ecotope. This paper mainly exam-ines the present composition of water resource in Beijing lower mountainousarea and anticipates the balance of water supplies and demand, as well asits potential development, to provide the scientific basis for the developm-ental strategy of orchard belt.
