摘要
对北京市山区风景林现状进行了分析,发现全市各区县山区风景林面积分布不均,主要集中在昌平区(8022.1 hm2)、海淀区(5881.9 hm2)、门头沟区(4999.8 hm2)等少数几个区县,且有77%面积的山区风景林由中幼龄林构成。从风景林树种组成上来看,由纯林组成的风景林面积比例较大;树种也主要集中在少数几个树种上,不利于风景林林分稳定,也降低了风景林观赏性。针对北京市山区风景林现状,笔者提出采用分类经营措施,按照分类经营原则,将北京市山区风景林划分为游憩型风景林和生态型风景林,同时对风景林经营措施进行了初步探讨。
According to the analysis of the current situation, it was seen that the scenery forest in mountain was unevenly distributed in Beijing. It mainly included Changping district (8 022.1 hm^2) , Haidian district (5 881.9 hm^2) and Mentougou district (4 999.8 hm^2 ). The young and middle-aged forest occupied 77% of mountain scenery forest. From the composition of tree species, a large proportion of mountain scenery forest composed of pure stand and mainly several trees species. The situation was not propitious for maintaining stand stability of scenery forest. It reduced the landscape. To resolve the current issue, management measures of forest classification was recommended. Furthermore the mountain scenery forest could be divided into two types, i. e. , recreational scenery forest and ecological scenery forest.
