河南南山林场栎类林健康评价研究

Health Assessment of Quercus Forest in Nanshan Forest Farm of Henan

以河南南山林场栎类林为研究对象,依据专家咨询法对健康评价指标进行筛选,用层次分析法和熵权法确定指标阈值,构建了栎类林评价指标体系,对栎类林不同生长阶段进行了健康评价和分析。结果表明,栎类林小班中处于优质、健康、亚健康和不健康状态的小班比例分别为2.85%、6.85%、61.40%和28.91%。幼龄林处于优质、健康、亚健康和不健康状态的小班比例分别为0.00%、5.88%、44.12%和50%;中龄林处于优质、健康、亚健康和不健康状态的小班比例为2.99%、10.45%、62.69%和23.88%。南山林场栎类林整体处于亚健康状态。因此,应加强对中幼林的经营管理,以提高栎类林的健康等级。

The health status of Quercus forest located in Nanshan Forest Farm,Henan province was evaluated.We screened indicators by the method of expert consultant.Analytic hierarchy process and entropy method was adopted to determine weights and thresholds.The different growth stages of was Quercus forest assessed.The results showed that,the quantity proportions of superior,healthy,sub-healthy and unhealthy states were 2.85%,6.85%,61.40%and 28.91%,respectively;in young forests,the corresponding figures were 0.00%,5.88%,44.12%and 50.00%,respectively;in middle-aged forest they were 2.99%,10.45%,62.69% and 23.88%,respectively.Both the young and middle-aged Quercus forests were sub-healthy status.Therefore,management should be strengthen to improve the health level of Quercus forest.
