摘要
森林公园承担着保护环境及生物多样性和供人们游憩的双重功能，为了使森林公园的树木保持现有的自然状态而免于破坏，同时，使森林生态系统水分平衡、改良土壤和美化环境等所需要的水量。文章研究并模拟测算国家级森林公园森林植被生态用水量定额。运用FAO-56推荐的Penman-Monteith公式进行模拟测算。测得老山国家级森林公园森林植被年最大生态用水量为44．367亿m^3，最小生态用水量为26．596亿m^3。认为生态用水是生态学、水文学研究的一个新领域，文章在研究过程中未能细致考虑林分特性，造成测算结果存在一定偏差，但对于国家森林公园生态用水研究领域也是一种新的探索，具有一定的参照意义。
Forest park undertake the water to protect the environment and biological diversity and also for peo- ple＇ s recreational, maintain the existing forest trees from destruction, balance the forest water ecosystems, im- prove soil and landscaping. This paper research and simulate the forest vegetation ecological water demand in Lao-Shan national forest park. The correlation analysis is used to apply the Penman formula which recommend by FAO-56. Estimate the max and min ecological water demand is 4.4367 billion and 2.6596 billion cubic me- ter. Ecological water is a new field of ecology and hydrology, this paper is un-fully consider the characteristics of forest stands, so the result maintain a certain bias. But it is also a new exploration of the ecological water demand for national forest parks.
