摘要
以湖南省有林地资源为研究对象,以城市供水制造成本的账面价值为基础,核算了近年的森林涵养水源价值。结果表明,2014-2016年,有林地年均涵养水源量为426.28亿t/年,年均涵养水源价值926.65亿元/年,单位面积提供价值7128.41元/hm^2·年,是按城市供水价格法核算结果的48.78%,相当于按影子工程法核算结果的35.59%。为准确核算森林涵养水源价值,应客观分析涵养水源功能的水文学过程、正确计量涵养水源实物量并规范核算城市供水的生产成本。
Taking forest land resources in Hunan Province as the research object,based on the book value of manufacturing cost of urban water supplies,the value of forest water conservation in recent years was calculated.The results showed that the average annual water conservation capacity of forest land was 42.628 billion per year from 2014 to 2016,and the average annual water conservation value was 92.665 billion per year,the Unit area value was 7128.41 yuan/hm^2 per year,which was 48.78% of the calculation result by the urban water-price method and 35.59% of the results calculated by the shadow-engineering method.In order to calculate the value of water conservation in forest accurately,it should objectively analyze the hydrological essence of water conserving function,measure the physical quantity of water source correctly and standardize the production cost of urban water supplies.
