老山国家级森林公园森林植被生态用水定额测算研究

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m3,最小生态用水量为26.596亿m3。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。

Estimation of Forest Vegetation Ecological Water Demand in Lan-Shan National Forest Park

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.
