基于模糊综合评判法的油茶林健康评价

Health assessment of Camellia oleifera lam based on fuzzy comprehensive judgement

针对油茶林健康无法准确定量评价的现状,尝试将模糊综合评判法应用于油茶林的健康评价中,通过查阅文献和专家咨询,建立一套由目标层、准则层、指标层和要素层组成的油茶林健康评价指标体系,应用Delphi-AHP法确定指标权重,引入模糊综合评判法评价湖南省浏阳市土桥林场油茶林健康状况.结果表明:土桥林场油茶林健康模糊综合评价值为3.3248,最大隶属度为0.5151,提示土桥林场油茶林总体处于亚健康状态,并有从亚健康状态向不健康状态方向发展的趋势,需要立即采取健康管理措施,保证油茶林的健康可持续经营.

At present, the health condition of Camellia oleifera lam can not be evaluated accurately and quantitatively, therefore the author attempts to apply the fuzzy comprehensive judgement to the health assessment of the Camellia oleifera lain. A set of health assessment indicator system of Camellia oleifera lam was established, which is made up of target-layer, criterion-layer, index-layer and element-layer by looking up some literature and expert advice, appling the Delphi-AHP method to determine the index weight, introducing the fuzzy comprehensive judgement to assess the health condition of Camellia oleifera lam in Tuqiao Forest, Liuyang city, Hunan province. The results show that its fuzzy comprehensive assessing value is 3.324 8 in the Camellia oleifera lam of Tuqiao Forest, the largest membership degree is 0.515 1.These indicate that Camellia oleifera lam in Tuqiao Forest is under sub-health condition. So it is essential to take some healthy measures immediately to ensure the healthy condition of Camellia oleifera lam and prevent the trend from the sub-health condition to unhealthy one.
