百里杜鹃国家森林公园盛花期游览路线选择

为探索贵州百里杜鹃国家森林公园盛花期游客游览路线选择及森林公园管理建设改善方案，选择杜鹃盛花期晴朗天，以普底景区8个游憩地为监测点，通过研究不同监测点大气颗粒物浓度、人体舒适度指标及美景度值等因子的变化，为游客、管理者提供参考。结果表明，8个监测点大气颗粒物日均浓度皆低于Ⅰ级标准，日变化规律均为上午高、中午低、傍晚略有回升；园内人体舒适指标总体较高，仅在7：00时，监测点S2、 S3和S8感觉不舒适，其余时段各监测点皆处于舒适或很舒适状态；美景度平均值从高到低的区域依次为杜鹃林林缘、空旷地、杜鹃林林内和无花针阔叶混交林，且因太阳高度角及光线强度变化，各监测点在不同时间段美景度有所不同。

The observations showed that the daily average concentration of atmospheric particulate matter was lower than grading standards I from 8 monitoring points in the park.The daily variation rules of atmospheric particulate matter concentration in the park went up in the morning and down at noon, and picked up slightly at dusk.The comfortable degree of human body was high in the Park. Generally speaking, the comfortable degree of human body was in a state of comfortable or very comfortable at other periods, but S2, S3 and S8 were not in a state of comfortable at 7:00 am.The azalea forest edge, the clearing, place inside the azalea forest and non-floricome broad-leaved mixed forest were successively ranked from high place to low place in terms of the beauty degree average standard.The best viewing angle varied from different time due to the changing of solar altitude and light intensity.
