摘  要：
该文利用河北省山区连续清查样地调查数据,从森林生态环境背景、森林生长状态和森林自然性3个方面来构建森林生态环境质量评价的指标体系,同时采用层次分析方法、生态因子质量等级评分法、加权综合质量指数法系统地评价了河北省山区森林生态环境功能质量状况.结果表明:①在1988—2001年,河北山区森林生态环境功能质量尽管有些波动,但总体上呈现逐渐变好的趋势.②河北山区森林生态环境功能质量等级好、中、差所占的比重大小悬殊,其中质量等级为中等的所占比重最大,说明了河北山区提高森林生态环境质量还有很大的潜力.③1988年以来,森林自然性指数值随时间呈现出总体上的变小趋势,说明了该地区森林受到人为干扰程度在日益加重.

摘  要：
Based on the successive inventory data in mountainous regions of Hebei Province, the composite indicator system of regional forestry eco-environmental quality evaluation was proposed. The authors suggested that the system should be composed of three aspects including the background of eco-environmental quality, status of forestry growth and naturality of forests. The value of forestry eco-environmental quality evaluation for mountainous regions of Hebei Province was analyzed from 1988 to 2001 by using the method of AHP, ecological elements quality scale marking and the weighed averages composite quality index. The results were as follows: 1)the forestry eco-environmental quality evaluation of mountainous regions of Hebei Province had some fluctuation from 1988 to 2000, but had a tendency toward good changes;2)the proportions of three forestry eco-environmental quality grades were very lopsided, and the middle grade was the biggest one. It shows that there are great potentials to increase forestry eco-environmental quality in mountainous regions of Hebei Province; 3)the indexes of mean value of naturality of forest show a tendency to decline over time since 1988. It indicates that the forests in this region are increasingly affected by disturbance from human activities.
