北京市门头沟区侧柏人工林多功能评价研究

Research and evaluation on multi-function of Platycladus orientalis plantation in Mentougou district of Beijing

以北京市门头沟区侧柏人工林为研究对象,采用定性与定量相结合的方式建立林分指标因子与林分功能的耦合关系模型,评价侧柏人工林各小班的森林多功能等级。结果表明:该区域侧柏森林多功能等级为优、良、中、差、极差的小班数量分别为9、11、23、5、7,占侧柏小班总数的16.36%、20.00%、41.82%、9.09%、12.73%,面积分别为91.3、66.3、145.6、34.1、80.1 hm2,分别占侧柏林总面积的21.87%、15.88%、34.88%、8.17%和19.19%,研究区侧柏人工林多功能水平较好,评价结果符合研究区实际情况。

Platycladus orientalis plantation in Mentougou District of Beijing was taken as the research object this paper. The model of coupling relationship between the index factor and function of the stand was built by the integrating qualitative evaluation with quantitative analysis. Then multi-function level of the sublots was evaluated based on the model. The results showed that the sublots withmulti-functional level of best quality, better quality, medium, poor quality and extremely poor quality are 9, 11, 23, 5 and 7 respectively,their percentages were 16.36%, 20.00%, 41.82%, 9.09% and 12.73% respectively. The areas of them were 91.3 hm^2, 66.3 hm^2, 145.6 hm^2, 34.1 hm^2 and 80.1 hm^2 respectively equal to21.87%, 15.88%, 34.88%, 8.17% and 19.19% respectively. The multifunction level of arborvitae plantation in the region was better according with actual conditions.The evaluation results would provide scientific basis for multi-function managing with arborvitae plantation in Beijing.
