摘要:
 随着灌木林的衰退老化，低质、低效等健康问题逐渐凸显，如何对灌木林健康状况作出评价已成为生态学领域和环境科学研究的热点之一。以库布齐沙漠柠条锦鸡儿灌木林为研究对象，通过生态学调查和等级评分方法，构建由4个一级指标，22个二级指标组成的柠条锦鸡儿健康评价指标体系，具有便捷性和适用性。采用专家打分法和AHP层次分析法确定各指标权重，并利用生态系统健康综合指数模型计算。结果表明，库布齐沙漠柠条锦鸡儿灌木林整体综合健康指数为0.538 7，健康、轻度低质低效、中度低质低效、重度低质低效占比分别为7.69%、38.46%、46.16%与7.69%，整体处于中度低质低效健康状态，有向重度低质低效发展的趋势。林分活力、土壤条件、群落结构和枯落物条件等是影响柠条锦鸡儿灌木林健康主要因素。
Abstract:
 With the decline and aging of shrub forests,health related problems of low quality and low benefit (LQ&LB) gradually become prominent.How to evaluate the health status of shrub forests has become one of the hot spots in the field of ecology and environmental science.Taking Caragana korshinskii forest occurring in Kubuqi Desert of Inner Mongolia as the research object,an index system of health evaluation,consisting of 4 primary indexes and 22 secondary indexes,was established by ecological investigation and grading method to make the evaluation more convenient and applicable.Expert scoring method and AHP method were used to determine the weight of each index.The comprehensive health index of the shrub forests in Kubuqi Desert was calculated as 0.538 7 by using the established model.The proportions of the shrub forests with different health levels of healthy,mild-,moderate-,and severe-LQ&LB were 7.69%,38.46%,46.16% and 7.69%,respectively.The overall health status was in a moderate health state of LQ&LB,and there was a trend of development to severe LQ&LB.The main factors affecting the health of C.korshinskii shrub forest were stand vitality,soil condition,community structure and litter condition.
