摘要
在研究济南市南部山区森林涵养水源功能的基础上,利用替代工程法对森林的涵养水源总量进行了价值评价。研究结果表明,该地区林地枯落物层的蓄水价值为57.83万元,林地土壤层的蓄水价值为5938.74万元,林地土壤增加枯水期水量的价值为4463.02万元,森林净化水质的价值为8950.10万元,森林涵养水源的总价值为19409.69万元。研究为该区森林涵养水源功能的经济价值评估提供了科学的理论依据,对济南市的生态环境建设有着积极的指导作用。
The paper evaluated the water conservation function of forest in the south mountainous area of Jinan City, using the reflection engineering method, on the basic of the study of the substance quantity of water conservation of the forest. The result was that the whole value of water conservation of the litter-fall floor was 0.578 3 million yuan, the whole value of water conservation of the soil floor was 59.387 4 million yuan, the value of increasing valid water in th eperiod of low water was 44.630 2 million yuan, the value of purifying water was 89.501 0 million yuan and all the value of water conservation was 194.096 9 million yuan. The study provided scientific basis for the evaluation of water conservation function of forest in the area and it was useful for the construction of environment in Jinan City.
