| 摘 要： | 按广东省森林资源与生态状况综合监测体系的技术要求,于2005年对全省森林优势树种、公顷蓄积、公顷株数、植物生物量、生态功能等级、森林健康状况、森林景观等生态质量指标进行监测。监测结果分析表明:2005年,全省森林生态功能一般,森林林分质量不高,优势树种结构不合理,森林健康状况良好,森林景观度不高,森林生态系统受人为活动的严重制约和影响,省级生态公益林生态质量明显好于商品林,西北部岩溶地区石漠化对区域生态环境存在潜在威胁。

| Abstract: | A monitoring on Ecological Quality Index(EQI) was conducted based on techniques of comprehensive monitoring system of forest resources and ecological status in 2005 in Guangdong province.The EQI includs dominant tree species,the volume per hectare,numbers of per hectare,plant biomass,grade of ecological function,status of forest health,forest landscape etc..The analysis of monitoring results indicated that the forest ecological function has less significant effects with its inferior stand quality and improper dominant tree species,the quality of forest landscape is also poor despite of its good health condition,the system is an artificial ecosystem which is seriously affected by human activities,and the eco-quality of provincial non-commercial forest is evidently better than that of commercial forest,the rock desertification in the northwest karst area is a potential threat to regional eco-environment. |
