摘要
通过在海口林场选取22块典型样地对其生产力、群落结构、抵抗力、土壤状况4个方面进行调查分析,运用森林生态系统健康指数(FEHI)评价模型评价昆明市国营海口林场的森林健康状况。结果表明:不同树种组成的林分健康程度不同,华山松林>柏树林>桉树林;同一树种,不同林龄阶段的林分健康程度也不同,成熟林>近熟林>中龄林。22个典型林分类型中,处于亚健康的样地有11个,占总数的50.0%;处于健康的样地有10个,占总数的45.5%;处于良好健康的样地为1个,占总数的4.5%;不健康和优质健康类型没有;综合评价表明,昆明市海口林场的森林健康状况为健康状态。
22 typical plots in Haikou forest farm of Kunming were selected for the investigation on its productiv-ity,community structure,resistance,soil conditions.The forest ecosystem health index （FEHI）model was used for the evaluation on the forest health status.The results showed that different species composition of forest lead differ-ent health degree,Pinus armandii forest〉Cypress forest〉Eucalyptus forest;The health status is different for the same tree species with different forest age,matures forest〉near-mature forest〉middle aged forest.In the 22 sam-ple plots,1 1 plots are in sub health,accounting for 50. 0% of the total,10 plots are in health,accounting for 45. 5% of the total,only one in good health and accounting for 4. 5%of the total,unhealthy and high-quality forest are none.In general,forest health status of Haikou forest farm is healthy.
