摘要： 为建立天然油松健康评价体系，解决天然油松林的经营与养护问题。本研究试验在北京市延庆区松山自然保护区天然油松林内开展，在试验区内随机选取50 株天然油松样本，对油松营养指标（油松一年生松针全N、全P、全K 含量、油松2年生松针全N、全P、全K 含量）进行一一评价，并建立油松健康评价体系。结果如下：以北京松山自然保护区天然油松林内天然油松为研究对象，通过专家评价法对营养指标进行健康程度评价，建立了油松营养指标健康评价体系，将油松健康状况分为3个等级，即健康、亚健康和不健康。其结果是，所调查油松样本中健康油松占80%，亚健康油松占14%，不健康油松占6%.

Abstract: In order to establish the health evaluation system of Pinus tabulaeformis, and to solve the problem of managing and protecting the natural Pinus tabulaeformis forest, a study was conducted in Beijing Songshan Nature Reserve Natural Pinus tabulaeformis forest, Yanqing County, Beijing, by randomly selecting 50 natural Pinus tabulaeformis samples from the experimental area. The authors evaluated the health standards of Pinus tabulaeformis respectively from the nutrition indexes, including the content of total N, total P, and total K of annual pine needle, the content of total N, total P, and total K of biennial pine needle. The results were as follows: regarding natural Pinus tabulaeformis of Beijing Songshan Nature Reserve Natural Pinus tabulaeformis as the research objects, the evaluation of the health of each index was carried out through the expert evaluation method, the Pinus tabulaeformis nutrition index health evaluation system was established, and the health condition of Pinus tabulaeformis was divided into 3 levels: healthy, sub-healthy and unhealthy. The evaluation result showed that healthy Pinus tabulaeformis accounted for 80%, sub-healthy Pinus tabulaefornmis accounted for 14%, and unhealthy Pinus tabulaefornmis accounted for 6%.
