摘要：在科学性、系统性、相对独立性和可操作性原则的指导下,从立地条件、土壤状况、生产力、群落结构、抵抗力及恢复力6个方面选取16个指标,构建了九龙山森林功能评价指标体系并确定评价标准,最后运用改进的TOPSIS法对23块样地进行了综合评价。结果表明:23块样地中,功能较好的共6个,功能中等的共10个,功能较差的共7个,说明研究区的森林功能不高,急需通过采取有效的经营措施来提高森林功能等级,改善森林状况,以实现研究区森林可持续发展的目的。从实际效果来看,改进的TOPSIS法具有一定科学性和可操作性,对北京地区森林功能评价具有参考价值。
Based on the principles of scientificity, systematic, relative independence and operability, 16 assessment indices were selected from the six aspects of site conditions, soil conditions, productivity, community structure, resist- ance and resilience, and an assessment index system of forest function in Beijing Jiulong Mountain was conducted. In the meantime, the standard of assessment indices was determined. Finally, the function status of 23 plots was evalua- ted by using the improved TOPSIS method. The results showed that among the 23 plots, those in the better, medium and poor function were 6, 10 and 7, respectively, indicating that the function of most of the plots were low, and were badly in need of taking effective action to raise and improve forest function status in order to achieve forest sustainable development of the study area. From the viewpoint of practical effect, it can be concluded that the improved TOPSIS method is scientific, feasible and it can provide references for forest function assessment in Beijing.
