基于加权面积比重的乡村人居林总体质量评价方法

选取与乡村人居林关系最为密切的林木覆盖指数、林木结构指数、林网密度指数、林木健康指数和林木稳定指数指标,利用层次分析法确定权重系数,通过间接构建评价指标各要素占评价区域加权面积比重的方法,进行乡村人居林质量评价,结果表明,4个代表型村庄人居林建设质量差异较大,以南书村为最好,上浦村和扁山村其次,茜黄村最差,综合评价得分分别为75.7972分、52.7972分、41.5418分和9.7689分.这种评价方法科学有效、简单快速,实用性强,避免了传统评价方法基础数据获取困难和可操作性不强的缺陷,为乡村人居林质量评价提供依据.

Quality Evaluation Method of Village Human Habitat Forest Based on Weighted Area Proportion

The article selected the indexes,included forest cover,structure,networks density, health and stability which were closed relationship with village human habitat forest,using analytic hierarchy process to determine the weight coefficient,through indirect building the weighted area proportion of various elements of evaluation index of the total size of the area.and getting the quality evaluation results of village human habitat forest.Results showed that the quality of village human habitat forest construction were more different between four types of village, the best village was Nanshu village,the next were Shangpu village and Bianshan village,the worst was Qianhuang village.The evaluation scores were 75.7972,52.7972,41.5418 and 9.7689. The evaluation method was scientific and effective,simple and rapid,practical,avoiding the defects of traditional evaluation method data acquisition difficulties and operational difficulties,the method provided theoretical basis for the quality evaluation of village human habitat forest.
