    摘要:

    基于森林资源二类调查数据,应用InVEST模型对北京山区生物多样性和碳储量进行了评估和估算,并讨论了二者之间的相互关系。结果表明,在所有森林生态类型中,单位面积生物多样性得分最高的是天然桦树林,为0.76;得分最小是人工油松林,为0.49。北京山区总碳储量为49 193 742t,总碳储量最大的是人工经济林,为10 402 900t;得分最小的是天然针叶林,为423 132t。各森林类型的单位面积平均碳储量均较高。一般来说,生物多样性较大的森林生态类型碳储量也较大,生物多样性与碳储量有一定的相关性,但并不十分明显。

    Abstract:

    Based on the data of Beijing forest resources inventory,biodiversity and carbon storage of different forest ecosystem types in Beijing mountainous areas were evaluated by using InVEST(the integrated valuation of ecosystem services and tradeoffs tool)model.The relationship between them was also discussed.Results showed that the highest biodiversity was 0.76in natural birch,while the lowest one was 0.49in artificial Chinese pine.The total carbon storage of Beijing mountain area was 49 193 742t,with the highest one being 10 402 900tin artificial economic woodland and the smallest one being 423 132tin natural coniferous.The average carbon storage per unit area was relatively high in all of the forest types.In general,the carbon storage of one forest type is higher when the biodiversity is high.Biodiversity has a certain correlation with carbon storage,but the correlation is not very significant.
