| 为给游客森林康养游览路线选择提供参考及公园景观生态景观规划设计提供数据支持，于2019 年 8 月 14 日 -8 月 17 日及 2020 年 1 月 13 日—1 月 16 日对公园内 5 种杉木群落结构类型进行空气负离子浓度观测及分析。结果表明：（1）夏季负离子日均浓度值从高到低为：杉木 Cunninghamia lanceolata+ 水体旁＞杉木 + 阔叶混交林＞杉木 + 空旷地＞杉木 + 阔叶林 + 竹林＞杉木 + 竹林；（2）冬季负离子浓度日均浓度值从高到低依次为杉木 + 水体旁＞杉木 + 空旷地＞杉木 + 阔叶混交林＞杉木 + 阔叶林 + 竹林＞杉木 + 竹林；（3）不同杉木群落结构类型夏冬季负离子浓度变化趋势多数呈现“V”或“U”型；（4）除杉木 + 竹林类型以外，同种杉木群落结构均表现出夏冬季负离子浓度差异性显著，夏季负离子平均浓度高于冬季；（5）不同杉木群落类型空气负离子浓度的差异性在夏冬季表现为极显著、显著及不显著；（6）夏季、冬季空气负离子浓度达到 4 级以上标准，具有基本森林康养功效。研究结果表明石门森林公园夏季比冬季更适合做森林康养及户外旅游活动。 |

| Abstract: |
| To provide data support for the selection of tourist routes for forest health and wellness tours and the planning and design of park landscape ecological landscapes,observation and analysis of the concentration of negative ions were conducted in five types of Cunninghamia lanceolata community structure from August 14th to August 17th, 2019 and January 13th to January 16th, 2020. The results showed that:(1) The daily average concentration of negative ions in summer from high to low was C. lanceolata + beside the water> C. forest>C. lanceolata + bamboo forest;(2) The daily average concentration of negative ions in winter from high to low was C. lanceolata + beside the water> C. lanceolata + open land> C. lanceolata + broad-leaved mixed forest>C. lanceolata + broad-leaved forest + bamboo forest> C. lanceolata + bamboo forest;(3) In summer and winter season,most of the negative ions concentration trend showed “V” or “U” shape in different types of C. lanceolata community structure;(4) Except for the type of C. lanceolata + bamboo forest,the same type of C.
lanceolata community structure showed that there was a significant difference in the concentration of negative
ions in summer and winter,and the average the concentration of negative ions in summer was higher than that in
winter;(5)The differences in air anion concentrations of different C. lanceolata community types in summer and
winter were extremely significant, significant, and insignificant.(6)In summer and winter, the concentration of
negative ions in the air reaches the level 4 and above, which has the basic forest health function.(7)The research
results showed that Shimen Forest Park was more suitable for forest health and outdoor tourism activities in
summer than in winter. |
