摘  要：
利用分布式测算方法,从生产力指标、结构指标、干扰指标和服务功能4个方面构建了广丰县森林生态系统健康评价指标体系。结合当地森林资源二类清查数据与实地调查数据,对江西省广丰县森林生态系统健康状况进行了评价,评价结果显示:全县5种主要森林类型中,阔叶林和杉木林健康状态林地比例最大,其面积分别为3 887.2 hm2和2 875.4 hm2,占总面积的41.28%和33.11%;毛竹林以较健康状态为主,面积为4 689.1 hm2,所占比例51.86%,油茶林以不健康状态为主,面积5 428.2 hm2,所占比例为41.72%。全县21个乡镇级测算单元,其中4个乡镇测算单元的森林生态系统是处于健康状态,7个处于较健康状态,5个处于亚健康状态,5个处于不健康状态。从整体上看,广丰县森林生态系统健康指数为9.76,属于健康状态,主要原因有以下3方面:林地数量的增加、森林质量的提高与林业政策的落实。

摘  要：
Distributed calculation method was used to establish the health assessment index system of forest ecosystem in Guangfeng County from the productivity index,structure index,disturbance index and the service functions.The forest ecosystem health in Guangfeng Country was evaluated based on the data obtained from the forest resource inventory and the field investigations.The result showed that: in the five major forest types in the Guangfeng County,the proportions of healthy broad-leaved forest and fir forest were the largest,the areas were 3 887.2 hm2 and 2 875.4 hm2 respectively,occupying 41.28% and 33.11%,respectively,of the total area;the most of Phyllostachys pubescens forest was in a relatively healthy state,the area and the proportion of that were 4 689.1 hm2 and 51.86%;the most of camellia forest was in a non-healthy state,the area and the proportion of that were 5 428.2 hm2 and 41.72%.Among 21 township-level estimate units of Guangfeng County,the forest ecosystems of 4 township-level estimate units were in a healthy state;the forest ecosystems of 7 towns were in a relatively healthy state;the forest ecosystems of 5 towns were in sub-healthy state;the forest ecosystems of 5 towns were in a non-healthy state.Overall,the forest ecosystem health index of Guangfeng County was 9.76,the forest ecosystem of that was in a healthy state,there were three main reasons: increase of the forest land,improvement of the forest quality and implementation of the forest policy.
