摘要:
在广西雅长兰科植物自然保护区内,按兰科植物的垂直分布状况 设置3个气象观测站,对主要的气象要素进行连续8 a的定位对比观测, 以探讨兰科植物分布与气象因子的关系。结果表明:该区年平均日照时 数为1 333.7~1 698.7 h,随海拔的升高呈现高-低-高的分布格局。年平 均气温为16.8~20.4℃,直减率为0.55 ~0.62℃·hm-1。日平均气温稳定 通过10℃活动积温为4 959.5~6 787.0℃·a-1,直减率为264.0~368.6℃ ·hm-1。年地面平均温度为20.1~24.2℃,直减率为0.57~0.86℃·hm-1 。年平均降雨量为940.8~1 216.9 mm,随海拔的升高呈现低-高-低的变 化规律。年平均蒸发量为1 089.8~1 685.5 mm,其直减率为83.8~124.1 mm·hm-1。年平均相对湿度为79%~83%,随海拔的升高而递增。年平均风 速为1.2~1.8 m·s-1,随海拔的升高而递减。自然保护区与相似海拔的 乐业县气象站相比较,日照时数和稳定通过10℃的活动积温偏高,气温 年较差、地面温度、降雨量、蒸发量、相对湿度和风速偏小。并根据该 区兰花植物的垂直分布频度,分别与气象因子进行相关分析。
Abstract:
In Yachang Orchids Nature Reserve of Guangxi, according to the vertical distribution, three meteorological observatories were set, the main elements of weather in those observatories were also recorded for eight consecutive years to explore the relationship between the orchids distribution and the meteorological factors. The results showed that the annual average sunshine hours was 1 333.7~1 698.7 h, showing high  low  high patterns with the increase of elevation. The annual average temperature was 16.8~20.4℃ with the straight cut rate of 0.55~0.62℃·hm-1≥ 10℃ was 4 959.5~6 787.0℃·a-1 wiht the straight cut rate of 264.0~368.6℃·hm-1. The annual average surface temperature was 20.1~24.2℃ with the straight cut rate of 0.57~0.86 ℃·hm-1. The annual average rainfall was 940.8~1 216.9 mm, with the low  high low patterns along the increase of elevation. The annual average evaporation was 1 089.8~1 685.5 mm with the straight cut rate of 83.8~124.1 mm ·hm-1. The annual average relative humidity was 79%~83%, with the increase of elevation. The annual average wind speed was 1.2~1.8 m·s-1, decreasing of elevation. Comparing to the Yachang County meteorological; Station with similar altitude, the sunshine hours and accumulated temperature ≥ 10℃ increased, the ground temperature, precipitation, evaporation, wind speed and relative humidity decreased in Yachang Nature Reserve. According to this orchid frequency, the vertical distribution condition, the correlation analysis separately with the meteorological factors were carried out.
